Oregon Public Broadcast recently ran a story, “Solutions to Oregon’s drought could be found in the Deschutes Basin”, that had some good information but also errors and misleading statements that need to be addressed. Like most articles on water in the Deschutes Basin, it provided a false equivalence between the Upper Deschutes and the entire Deschutes River. “And yet, as a megadrought grips the West, the Deschutes Basin has rebounded from dire straits in the early 2000s. Today, conservation measures are leaving 10 times more water in the river than was protected for Mother Nature in 2002.” (Really?*) While it is true that the Upper Deschutes (headwaters to Bend) has seen an increase in flows, the Middle and Lower Deschutes are not seeing any benefit from piping.

Rebuttal to “The Truth About PGE’s Stakeholder Process”
Yesterday the Deschutes River Alliance made a post titled “The Truth About PGE’s Stakeholder Process“. I really hesitated to write about this, from my perspective it’s a tired topic, but they made some claims that I simply cannot ignore. I was a member of the stakeholder process and have a very different perspective of what occurred. To state that the DRA is “the only NGO fighting for the lower Deschutes River” is simply ridiculous.
Read More »Deschutes Fisheries Workshop presentations
I’ve already written about some of these, and will dive into one more soon, but PGE has posted all the presentations from the recent Fisheries Workshop. Of the ones I have not already covered, or plan to, I would draw your attention to “Lessons Learned from a Decade of Reintroduction”, “Adult Returns Update”, and “Pelton Round Butte Water Quality Update”. Good stuff, in my opinion.
Less than 3 days, more than 40 trout
Yesterday my friend Tim and I finished up 3 days on the Deschutes, floating from Trout Creek to Harpham Flat. Like I said in this post from about a month ago, I don’t care what anyone with an agenda to promote says, the Lower Deschutes is in excellent shape. I had not been on this section of the river in some time, so I was curious about what I would find. The water was clear with no excess algae, aquatic plants were abundant and healthy, the banks were coated with caddis that birds and bats gorged on in the evening, black stonefly nymphs were everywhere in the river, and the fishing was excellent. The only bummer was that I landed 5 big Northern Pike Minnow, one of which was 15″ and 2 were 17″.
Read More »Lower Deschutes River fish population estimates
One of the presentations I look forward to every year at the Deschutes Fisheries Workshop is the ODFW report on their annual fish population estimates. There are many who continue to argue that the operation of the selective water withdrawal tower has been detrimental to redband trout. Once again, the science says otherwise. Redband trout continue to do well. You can see the presentation below, but here’s a summary. Steelhead returns continue to be low. Clearly, this is not due to the SWW, steelhead returns are low throughout the entire Columbia River Basin. Coho salmon returns are increasing. Spring chinook returns are critically low. Fall chinook returns are robust. Smallmouth bass are exploding in the Columbia River and seasonally move up into the Deschutes but they are not spawning in the Deschutes.
Read More »Lower Deschutes: fishing report, heresy, and some cool photos
Yesterday my friend Scott and I finished up 3 days on the Lower Deschutes. This has been an annual spring trip for me for many years. I went on a couple of day trips before stonefly season but decided to wait until the crowds had dissipated before heading back. The fish are still there and, once again, the fishing was excellent. I don’t care what anyone with an axe to grind or agenda to promote says, the Lower Deschutes is in great shape. Fish, aquatic insects, birds, and bats were abundant. Caddis covered everything, including my face at times, which was irritating. Lots of snakes this year as well. Some extreme weather events have clearly occurred since I was last on the river about a month ago. Scott, a professional hydrogeologist, was impressed. Keep reading for more and some cool photos.
Read More »2022-2033 steelhead reintroduction final count
Attempts to reintroduce summer steelhead into the Upper Deschutes Basin above the Pelton Round Butte hydroelectric project on the Deschutes River have been ongoing for over a decade. This past season saw 131 returning adults moved up into Lake Billy Chinook, the largest number so far, where they will hopefully naturally spawn. 131 adult fish remains a disappointing number, but it is two to almost three times the count over the past few years, and it points to the success fisheries managers at Portland General Electric are having adapting their management strategies in the face of the deteriorating outlook for steelhead over much of the west coast of North America.
Read More »2022-2023 Deschutes River steelhead return puzzle
We all know that 2021-2022 returns were disastrously low for wild steelhead in the Deschutes and most of the Pacific Northwest. ODFW estimates that only 523 wild steelhead made it above Sherars Falls, compared to 1,935 the year before. The current 2022-2023 Deschutes steelhead return year still has a few months to go but surprising data is emerging. Wild steelhead counts have improved but are still low, barely above the threshold for survivability as established by ODFW. Upper basin origin reintroduced steelhead, however, are likely to have their best return year ever. With a few months to go, returns this year are already almost 3 times last year.
Read More »Bull trout in the Lower Deschutes
In 2022 I caught more bull trout fishing the Warm Springs to Trout Creek stretch of the Lower D than I have in past years and heard similar accounts from other anglers. The fish have been bigger as well, 20″ was not unusual.
Read More »2021-2022 steelhead reintroduction final count
The 2021-2022 Deschutes summer steelhead season officially ended April 30. While steelhead can start appearing in the lower most sections of the Deschutes in June, most don’t arrive at the upper stretches until winter with stragglers arriving in March and April. According to Portland General Electric, the final reintroduction count for this past season is 46 steelhead. (Look at the spreadsheets from May 2021 through April 2022.) The 2020-2021 season saw 52 adult returns and the total for the season prior to that was 57. Clearly, the return of only 46 adult steelhead from the Upper Deschutes Basin is disappointing. On the other hand, the return of wild and hatchery adults in the entire river has been plummeting.
Read More »New Whitefish Record and a Healthy Deschutes
You’ve probably already read about the announcement yesterday from ODFW that a new state record whitefish was caught last month on the Lower Deschutes near Warm Springs. Congrats to Alex Dietz, it must have been fun. This is another example of the fact that the Lower Deschutes is in great shape and that fish are bigger since PGE’s Selective Water Withdrawal tour became operational. To be clear, there are ongoing issues but its past time for the misinformation campaigns to stop.
Pumping Water from Lake Billy Chinook: Too Many Unknowns
North Unit Irrigation District (NUID) is working on plans to pump up to 400 CFS of water from Lake Billy Chinook (LBC) for use by their patrons. The Bend Bulletin recently had a positive story about it as well as an editorial endorsing the idea. This could be an attractive idea but there are simply too many unknowns to have an informed opinion, and there are reasons for concern. The devil is in the details, and we don’t know the details.
My first reaction is that a pumping station at LBC will be another expensive taxpayer funded project for private benefit, may shift water availability and quality issues from one part of the Deschutes River to another, and would not be necessary if the core issues of the water scarcity crisis were addressed. Water waste and misappropriation is our disease. Do we need to spend another $400M of taxpayer dollars for pumping on top of the $1B dollars already needed for canal piping to cure it?
Read More »Steelhead Fishing Closure: Too Little Too Late?
By now you should be aware that two days ago ODFW partially closed steelhead fishing on a few rivers, including parts of the Deschutes during September. For the past three years I have been writing that this should occur, and not just for part of the Deschutes for a single month. Here’s a post I made just 3 weeks ago illustrating how “bleak” the returns have been. In their press release on August 27th, ODFW stated that steelhead returns so far this year are the lowest since counts began in 1938. As of August 20, steelhead counts at Sherars Falls on the Deschutes near Maupin were only 1/3 the already low 2020 counts. Above is a graph showing unclipped steelhead returns over Bonneville Dam, fish destined for all the tributaries of the Columbia. Note that unclipped mostly means wild, but not always. Some unclipped fish are actually hatchery fish that are part of steelhead reintroduction efforts, like in the Upper Deschutes Basin. Also note that the 10 year average in the graph is getting pretty low as the last 10 years have seen poor returns.
Read More »2021 Pelton Round Butte Fisheries Workshop Executive Summary
Portland General Electric and the Confederated Tribes of Warm Springs, co-owners of the Pelton Round Butte Hydroelectric Project on the Deschutes River, held their annual fisheries workshop today. I have been attending these events for many years and can wrap this one up pretty easily. While some of the numbers have changed, the bottom line is that the goal of reintroducing summer steelhead, spring chinook, and sockeye into the Upper Deschutes Basin remains elusive. The number of returning adults of all three species continues to be a small fraction of what is required for self-sustaining populations. That being said, there are good, dedicated people working on the effort and they continue to adapt based on the results of on-going scientific work. Also, the Oregon Department of Fish and Wildlife reported that their annual fish sampling once again shows that the operation of the Selective Water Withdrawal tower has had no negative impact on trout populations in the Lower Deschutes River. As detailed in their presentation, trout density and size continues to be the same or better than before the SWW become operational. In a follow up conversation, ODFW confirmed that trout condition factors (health) also continue to be good. I believe that reintroduction remains a worthwhile effort. The biggest issues remain outside the control of PGE/CTWS: low flows in the Crooked River (where most fish want to go), high temperatures, and poor ocean conditions.
More Cold Water Being Released into the Lower Deschutes River
The recent heatwave caused Portland General Electric to release 25% cold bottom water a few days ago into the Lower Deschutes River. The lower river once again has the temperature it would have if the Pelton Round Butte hydroelectric complex was not there. PGE says they will be able to release more cold water in July. Good news for Deschutes anglers.
2020-2021 Steelhead Reintroduction Final
Portland General Electric provided the final reintroduction counts for the 2020-2021 steelhead season last Friday* and once again they were extremely disappointing: a total of 52 steelhead. These are fish from the Upper Deschutes Basin that were captured as out migrating smolts 2 years ago at the Selective Water Withdrawal tower in Lake Billy Chinook, potentially marked and released into the Lower Deschutes River, and which subsequently returned as adults. Last year 57 adults returned. It is almost important to know that the number of all steelhead (wild, hatchery, and reintroduced) captured at the Pelton Trap was very low (1,309).
Once again, I make the case that this is not an issue specifically with the Deschutes River, it is a result of many factors that have led to massive declines in anadromous fish populations throughout the Pacific Northwest. These include global warming which is destroying the food chain in the ocean as well as lowering and warming rivers, dams which remove habitat and impede migration, over fishing, pollution, cross-breeding and competition with hatchery fish, etc. Without large scale reform, wild steelhead in much of the Columbia Basin and beyond are on the path to extinction and hatchery fish could follow.
For those of you who track the reintroduction closely, keep reading.
Read More »Why are salmon and steelhead on the path to extinction?
The Bend Bulletin recently published an article from the Associated Press titled “Study: Ocean conditions, not dams, reduce salmon runs”. This is misleading reporting of the original study, “A synthesis of the coast‐wide decline in survival of West Coast Chinook Salmon”, published in the Fish and Fisheries journal.
The research study argues that the most prized salmon and steelhead populations along the west coast of North America are in decline, often dramatically so, and that the reasons are complex. Dams are not the sole culprit. This can be a controversial statement in many environmental circles, but it is true. It is well known that anadromous fish are declining in river systems that are not impacted by dams as well as where dams are present. This is not an either-or proposition, however.

“Day Trip” Steelhead Update
For Central Oregonians, the “day trip” on the Deschutes is the stretch from Warm Springs to Trout Creek. While steelhead counts on the Columbia are somewhat elevated from last year’s dismal numbers, it has not translated into good returns on the day trip section so far this season. According to fish counts on the PGE website, a total of 186 steelhead have been captured at the trap near the base of the Pelton Reregulating Dam from May through October. Of those, 8 were true wild fish and were returned to the river. 15 of the fish were planted as fry or smolts above Lake Billy Chinook. Most of these will be released into LBC with the hope they will naturally reproduce in the Crooked River or Whychus Creek. The 163 hatchery fish will mostly be used as brood stock for future hatchery production. These are small numbers, but the next three months typically see the most fish arrive. Keep your fingers crossed.
Lower Deschutes Fish Update
From my perspective, one of the highlights of the Deschutes Fisheries Workshop is the annual report on lower Deschutes fish from ODFW. That presentation did not occur this year, so I talked to Rod French, ODFW Mid-Columbia District Fish Biologist which includes the lower Deschutes. There was a surprise, read on for more.

I have looked forward to attending the annual Deschutes Fisheries Workshop for many years. It has been the place to hear the latest, best available science on what is happening in the Deschutes River, some of its tributaries, and anadromous fish reintroduction efforts. I found the online event yesterday to be disappointing, however. Part of that is due to the lack interaction with others in the hallway, during a meal, or at the bar. The organizers are not to blame for that, they have no control over the pandemic, but they could have provided a lot more content. Here’s my summary and criticism of the 26th annual meeting

This year’s workshop is being held online on July 23rd. Before COVID these workshops were 1.5 days and filled with great information. I have been going for years and always learn from them.

2019-2020 Steelhead Season Reintroduction Final Count
“We have met the enemy, and he is us”. – Pogo
Adult steelhead start arriving in the Upper Deschutes during the summer and continue through the following April. (Steelhead are amazing.) Today, Portland General Electric released their April adult fish count for the Pelton Trap near the bottom of the re-regulating dam. A total of 57 adult steelhead returned during the 2019-2020 season. 22 of them were released as fry into the upper basin and 35 were released as smolts. There’s no denying that 10 years in, this is a disappointment.Read More »
Upper Basin Steelhead Return Update
Believe it or not, if you look at the individual fish count numbers on the PGE website for past years, summer steelhead season in the upper most stretches of the Deschutes extends to the end of April. Some of these fish really take their time to get to their final destination. So, while the return season is not over, we are getting close. As of March 6th, 53 steelhead have been passed above the dams into Lake Billy Chinook. 47 of those were recently counted via radio tags, 22 in the Crooked River, and 3 in the Crooked arm of Lake Billy Chinook, presumably getting ready to head up the river. This once again shows the importance of the fish ladder at Opal Springs.
DRA Opinion Piece Response
The July 24th Source Weekly contained a guest column by Greg McMillan, president of the Deschutes River Alliance, that needs a response. It is absolutely true that attempts to reintroduce salmon and steelhead into the upper Deschutes basin above Lake Billy Chinook have been extremely disappointing. It is important to understand, however, that adult returns for salmon and steelhead have been plunging in the entire Columbia River basin and much of the Pacific Northwest. The truth is that many anadromous fish runs are on the path to extinction due to habitat loss, dams, over harvest, hatcheries, and the heating of the Pacific which has led to the collapse of the food web in many areas. This has nothing to do with local reintroduction efforts.Read More »
Lower Deschutes Fish Update
Rod French, ODFW’s Mid-Columbia District Fish Biologist, presented at last week’s Fisheries Workshop. This annual presentation by ODFW has been largely unchanged for years, which is excellent news. Trout have been surveyed in the lower Deschutes since the 1970s and there have been no observed negative impacts on them from the operation of the Selective Water Withdrawal tower in Lake Billy Chinook. If anything, trout are larger and more abundant now, which is to be expected given the more natural temperature profile of the river. Below are a lot more details, or take a look at Rod’s presentation.Read More »
Fisheries Workshop Highlights
The 25th annual Pelton Round Butte Fisheries Workshop was the past two days. I have been going for years and, as usual, it was an overwhelming amount of information. I plan to follow up with some of the presenters to get a better understanding of their data and hope to have more detailed posts soon. In the meantime, here’s a quick list of the highlights from my perspective.Read More »
Artifishal: Not a Complete Picture
Last night I attended the Bend premier of Artifishal, “a film about people, rivers, and the fight for the future of wild fish and the environment that supports them. It explores wild salmon’s slide toward extinction, threats posed by fish hatcheries and fish farms, and our continued loss of faith in nature”. Produced by Patagonia and heavily promoted in the Pacific NW by the Native Fish Society, I found the film to be visually and emotionally powerful but lacking in nuance. Clearly, hatcheries are a problem for wild fish, but they are only part of a complex web of issues.Read More »
PGE Water Quality Study
Portland General Electric’s long awaited lower Deschutes River water quality study was recently released. At over 600 pages it took me some time to get through, here are my initial impressions. This study is critically important to the ongoing effort to reintroduce anadromous fish into the upper Deschutes Basin and the operation of the Selective Water Withdrawal tower. Also note that the Deschutes River Alliance’s lawsuit against PGE/CTWS (dismissed but under appeal) is based on allegations of water quality violations. The author of the water quality study will present and answer questions at the upcoming Fisheries Workshop. Read More »
Upper Basin Kokanee & Sockeye
I don’t write much about kokanee and sockeye, but they are part of the effort to reintroduce anadromous fish into the upper Deschutes Basin. The tribes frequently talk about the cultural significance of sockeye but they seem to be of secondary importance in reintroduction efforts. As a fly angler who likes to target large fish, I am also very aware that kokanee are the primary food source for bull trout in Lake Billy Chinook.Read More »
Prepping for the Fisheries Workshop
The annual Pelton Round Butte Fisheries Workshop is rapidly approaching so I have been reviewing notes from last year along with updates since then. I’ll make a few posts from that review over the next week. Like I have said before, if you are interested in learning about what is really happening in the lower Deschutes River, Lake Billy Chinook, and anadromous fish reintroduction efforts, you should attend.
Spring Chinook Returns: Commentary
Portland General Electric has recently been talking about above average returns of reintroduced spring chinook this year. I first saw mention of this in their June newsletter, then there was this story on KTVZ, and then today’s story in the Bend Bulletin. I hesitated to write about these returns but given the coverage, here’s my two cents. Without a doubt this is good news but with a total of 46 adult fish so far this year returns remain dismal. PGE is crediting the improvement to operational changes, specifically releasing hatchery reared smolts rather than fry along with nighttime operation of the Selective Water Withdrawal tower during out migration periods. I certainly hope these are the reasons. Time will tell, however, if this is an aberration, like the recent one year spike in Sockeye returns that has not repeated itself, or the beginning of a true recovery. I’m hopeful, but cautious.
Reminder: Pelton Round Butte Fisheries Workshop & Water Quality Study
As I have written about repeatedly in the past, if you want to hear the latest science and updates on what is happening in the Lower Deschutes, you should attend the Pelton Round Butte Fisheries Workshop. The 25th annual workshop is next month, July 17 & 18, at The Riverhouse Convention Center in Bend. You can sign up and get the agenda here. This meeting should be especially interesting. Along with the normal updates on salmon and steelhead reintroduction efforts, the results of the long overdue water quality study will be released. You can read the latest PGE/CTWS newsletter via the link above. The complete water quality study will be posted on their site on June 20, so come to the workshop prepared to ask questions. I hope to see you there and, as usual, will post my summary of the meeting.
CORRECTED: Final Steelhead Numbers
The official Deschutes steelhead season is from April 1 to March 31, so the 2018/2019 season is now over. Today, PGE released their March monthly newsletter which stated that a total of 35 upper basin origin adult steelhead returned and were passed above the Pelton Round Butte project and released into Lake Billy Chinook. Clearly, this is a dismal number. You can see the number of smolts that were released downstream here. Assuming that adult returns were from 2016 smolts that’s a return rate of only 0.87% (not 8.7%, I missed a decimal point in the original post). There is hope for some improvement in the adult return count, however, if not the percentage. In 2017 and 2018 steelhead smolt counts were much higher. 2017 was a better water year and in both years more smolts were planted. Starting next year only smolts will be planted. Read more about this here.
Upper Basin Anadromous Fry Stocking
This spring marks the last stocking of fry as part of the upper Deschutes Basin salmon and steelhead reintroduction effort. Yesterday I was part of the crew helping with the final chinook salmon fry stocking and backpacked fry into the lower Crooked River canyon as well as where Alder Springs meets Whychus Creek not far from the middle Deschutes. As I wrote about here, the reintroduction effort has been a disappointment for many reasons one of which is the unsuccessful fry stocking effort and a new approach is needed.Read More »
Oregon Chapter American Fisheries Society Meeting and Another SWW
Last week the Oregon Chapter of the American Fisheries Society held their annual meeting in Bend. I attended the 21 presentations on Water & Climate. I’ll make a few posts with highlights and, hopefully, some copies of presentations I have requested. One of the presentations was on the unintended consequences of selective water withdrawal at Cougar Dam on the South Fork of the McKenzie River. There are some interesting analogues to what is happening on the Deschutes.Read More »
The Osprey and a Critique
The latest issue of The Osprey is now available. If you like to read scientific articles about steelhead and salmon conservation, mostly in the Pacific Northwest, then this is the journal for you. I encourage you to subscribe and help keep them going. This issue has a couple of articles that once again illustrate the peril facing anadromous fish in many PacNW river systems. It also contains an article on the lower Deschutes River which I found problematic. Read More »
Deschutes Wild Steelhead Update
Unfortunately, as of the end of September things still look pretty bleak for wild fish this season. The trap at Sherars Falls has captured a total of 44 wild steelhead. Only 3 of these have made it to the the trap at the bottom of the Pelton Round Butte complex (Lake Billy Chinook, etc.). Two of those are actually hatchery steelhead that were released above Lake Billy Chinook but did not have their adipose fins clipped. As I detailed in a series of posts starting here, these fish could be on a path to extinction in the not too distant future.
Steelhead in Crisis, Time for a Management Change?
The following is a guest column I submitted to the Bend Bulletin a while back but which has not been published. It is a summary of some recent blog posts that I believe are worth further exposure in a timely manner.
Last year was one of the poorest on record for steelhead in the Deschutes. After some initial optimism for a modest rebound, the forecast for returns this season has been lowered to be even worse. The Oregon Department of Fish and Wildlife has now closed the entire Columbia River and lower John Day River to steelhead retention. ODFW went further and asked anglers to avoid steelhead fishing altogether for the remainder of the year. Wild steelhead are currently on a path to extinction in the Deschutes and entire Columbia Basin.Read More »
Reintroduction: Time for a Change in Strategy
After 10 years of effort it is clear that the current approach to reintroducing anadromous fish into the upper Deschutes Basin above the Pelton Round Butte project is not producing acceptable results. Fisheries managers acknowledge this but often state that it will take more time. They reply that it has been over 50 years since these fish were cut off from their traditional spawning grounds and reintroduction is a complex problem. This is true, but I believe the current dire state of steelhead returns to the Deschutes River should provide impetus to take bolder action. This is a long post, but worth reading if you care about the future of steelhead in the Deschutes River.Read More »
Cooler, cleaner water?
I got back from my latest fishing excursion (that’s a measured 27” wild, native rainbow trout) and saw The Bulletin published an editorial last Friday about the Deschutes River Alliance’s lawsuit being dismissed. What bothered me in their editorial was the use of the DRA’s tagline of cooler, cleaner water for the Deschutes. The facts on this topic are well established. The quantity of water in Lake Billy Chinook is not sufficient to keep the lower Deschutes “cooler” for the entire summer and “cleaner” is largely a function of agricultural and urban water runoff. Read More »
DRA Lawsuit Dismissed
The Deschutes River Alliance has argued for years that PGE/CTWS’s attempt to reintroduce anadromous fish into the upper Deschutes Basin has harmed the Deschutes River below the Pelton Round Butte complex of dams. As part of their advocacy the DRA brought a lawsuit against PGE/CTWS claiming that the project violated the Clean Water Act. On Monday the suit was dismissed for lacking “material fact”. Read More »
SWW juvenile outmigration
Most anadromous smolts outmigrate in the spring. While a few stragglers may still move through the system over the remainder of the year, at this point we have a pretty complete count of this year’s totals for fish moving from the Crooked, Metolius, and upper Deschutes rivers to the Selective Water Withdrawal tower in Lake Billy Chinook where they are captured and then released into the lower Deschutes.

Deschutes River Alliance water quality study
The Deschutes River Alliance recently released their 2017 lower Deschutes water quality study. I admire their continued efforts to be stewards of the lower Deschutes. I also remain critical of their work and have a simple question: if the water quality of the lower Deschutes is so bad then why are the fish so healthy and abundant? As an angler, that’s what I really care about. Perhaps the DRA should spend more time studying the fish and less time speculating about what may or may not happen to them based on their views of water quality.Read More »
Bull trout redd survey
I had a request to post the bull trout redd survey data. As you can see, there has not been a significant drop recently. There is also hydroacoustic data that shows a continued steady population of bull trout in Lake Billy Chinook. The big drop in 2006 is correlated with a drop in the kokanee population, the bull’s primary food source, after the bulls became too numerous to be supported by the ecosystem. Note that the redd count has stayed fairly constant since then and at a level above pre-SWW levels.
Lower Deschutes fish populations & health
At last week’s fisheries workshop, ODFW gave their annual report of fisheries population and health for the lower Deschutes. Since the 1970s they have been electrofishing the same stretches from Warm Springs to Jones Creek. As reported in past years, trout continue to be in excellent health. Condition factors were good before operation of the SWW and they are at least as good now. If anything, the fish appear to be growing faster and are larger.Read More »
Climate changes in Montana (and locally)
I was recently sent a link to an interesting article about climate change’s impact on fly fishing in Montana and the continued denial of the science by so many, even the local Trout Unlimited chapter. The article is part of a series by Inside Climate News. It was worthwhile reading and also reminded me of anglers venting about PGE causing changes on the lower Deschutes and not considering the undeniable changes we have seen in our local climate over the past few years. Clearly, the SWW has made an impact on the river, but so has a series of droughts, low water years, and year after year of record hot summers. Next week is the annual 2-day Deschutes fisheries workshop and I look forward to hearing the latest science on the lower D. Read More »
Three days on the lower Deschutes
Monday through Wednesday this week and friend Dan Pebbles and I floated the Deschutes from Trout Creek to Maupin. It was a great trip. It was hot, the river looked great, and the bugs were everywhere. We caught so many fish on the surface it was almost boring. They were uniformly healthy looking. Fat 14” to 16” fish were common, a few were measured at 18” plus/minus, a size that used to be unusual. The only problem with the float was the guide hatch. What a crowd! Seriously, there should be a much smaller limit. The cougar in camp early Wednesday morning was a new one for me, fortunately no damage was done. Of course, the lower D is a controversial and emotional issue for many. There’s still time to sign up for the annual Fisheries Workshop and get the latest science to form your own informed opinion.
End of the 2017/2018 Deschutes Steelhead Season
The Deschutes steelhead season officially ranges from April 1 until March 31. Below is a table with the final returns of adult fish to the trap at the base of PGE/CTWS’s Pelton Round Butte complex of dams. There’s no way to sugar coat the news, it’s simply bleak. There were record low returns of steelhead across all categories (see the table below). Read More »
A River (or Lifestyle?) Worth Fighting For
The Deschutes River Alliance has recently released a new video titled “A River Worth Fighting For” touching on their suit against Portland General Electric and the Confederated Tribes of Warm Springs alleging violations of the Clean Water Act. They spend more time illustrating economic hardship in Maupin which they attribute to those violations. While I am completely in favor of the Clean Water Act being enforced, and sympathetic to businesses who rely on tourism, I believe this video is misleading in many respects.Read More »
PRB Fisheries Workshop
For over 20 years Portland General Electric and now the Confederated Tribes of Warm Springs have been hosting the Pelton Round Butte Fisheries Workshop.
