One of the primary disagreements between the irrigators and conservation groups is the relative importance between canal piping and improving efficiency in the use of water. For a variety of reasons, the irrigators are focused on piping their main canals. The Basin Study Work Group, however, showed that water could be more cheaply and quickly saved via other techniques including the use of modern irrigation methods and simple water conservation. I saw a great example of this while on a hike along the Deschutes yesterday.Read More »
Tod Heisler has a great column in today’s Bend Bulletin titled, “The fallacy of in-conduit hydropower”. It’s worth reading, but the gist is that hydro power plants installed into piped canals encourages the continued overuse of water, even when it is not needed, in order to keep the power plant running. Of course, this maintains the irrigator’s legacy of keeping water levels in local rivers and streams below what is needed for a healthy ecosystem.
“The Deschutes River’s beauty hides problems”, was an editorial in yesterday’s Bend Bulletin. I continue to be pleased with the paper’s new commitment to environmental coverage. The problems facing the Deschutes River are numerous, complex, and often rooted in decisions made a century ago. Few people, or even some organizations claiming to be advocates for the river, really have a grasp of the broad range of interwoven issues: water law and rights, hydrology, global heating, tax policy, groundwater recharge, mitigation, economics, biology, etc. It really is a fascinating area that I have been studying for over a decade. In that context, I think the Bulletin’s editorial did a fine job of skimming the surface of a few current high-profile issues. In the future, I hope they can provide broader and more nuanced coverage.Read More »
Swalley Irrigation District and the Deschutes River Conservancy recently announced the completion of piping a 3 mile stretch of canal which will restore about 1.8 cubic feet a second (CFS) of flow to the Middle Deschutes during peak irrigation season. 1.8 CFS is about 13.5 gallons. Picture 5-gallon buckets, two full and one 2/3rds-full. Put them on their side and that’s the size of the stream they would create. Restoring water to the river is always good news, but this announcement is a great example of the complexity of the issue.Read More »
Today the Bulletin ran a guest column, “$1 billion is too much to give irrigation districts in these times“, by Tod Heisler of Central Oregon Land Watch. Clearly, I agree with Tod that the current plan is the wrong one. My first letter to The Bulletin criticizing water and canal management by local irrigation districts was over 10 years ago. Hopefully we can get past identifying the problem and finding real solutions to our local water issues before lack of adequate funding, a growing population, and a heating planet create a full-blown crisis. Of course, it already is a crisis for local fish and wildlife.
Today the Middle Deschutes below North Canal Dam was lowered to 74 CFS. The average for this time of year is 470 CFS. Historically it would be at least 1,000 CFS. I took the first photo this afternoon just below the dam, the river has been turned into frog water and much of the bank and what was habitat has been exposed. The second photo is at Sawyer Park. Look at this entry to see the see a similar view 10 days ago when it was at 310 CFS.Read More »
On March 30th the Bulletin had a front page article about some of the ecological problems facing the Upper Deschutes. In response, I quickly submitted a guest column pointing out that the Middle Deschutes is suffering from the same issues. They have not published my column, so here it is for your consideration.Read More »
As I recently posted, last Monday through early Wednesday the irrigators raised the level of the Middle Deschutes almost 50% from 410 CFS to 600 CFS before dropping it to 250 CFS in about 6.5 hours during the day Wednesday. Today I had to go into Bend so I stopped by Sawyer Park to take a look.
Unfortunately, I am given frequent reason to post about the environmental destruction to the Middle Deschutes from abrupt, drastic irrigation withdrawals. Today is a particularly egregious example. In 2 days flows in the river were increased from 410 to 600 CFS and then dropped to 250 CFS in just a few hours! Where’s the news coverage showing all the stranded fish in the side channels in the middle? Why don’t the irrigators slowly ramp down flows in the Middle Deschutes like they do in the Upper Deschutes? Business as usual for the irrigators is the business of environmental destruction.
Today I saw that one of the COID main canals near my house was full of water so I checked the graph. As you can see below, there have been some pretty dramatic fluctuations in the Deschutes below Bend over the past week. There was an abrupt diversion into the canals on February 10 and it looks like another is starting today. (Note that it can take a few days for the water to make it down the canals.) As I have written before, these sudden fluctuations wreak havoc on the aquatic environment and cause increased sedimentation which fills spawning beds.Read More »
On January 31 the Deschutes River Conservancy announced that they had secured funding from Intel Corporation to help with their middle Deschutes summer water leasing program. Without the DRC’s various efforts, including the leasing program, the middle Deschutes below Bend would be virtually dry in the summer. Additional funding for the leasing program is welcome news but requires some context.
Flows in the Deschutes above Bend are controlled by irrigation districts who withhold water to fill reservoirs in the winter and release water in the summer which is then diverted into a series of irrigation canals. The last major diversion is located at the North Canal Dam in Bend just upriver from the Riverhouse. During irrigation season the Deschutes below this dam is reduced to a relative trickle, dramatically damaging the ecosystem for fish and wildlife. Read More »
Today the US Fish & Wildlife Service held a public update meeting on the Habitat Conservation Plan status. I’ve written extensively on the HCP in this blog but, briefly, it is an application by Central Oregon irrigation districts and the City of Prineville to continue to withdraw water from local rivers while incidentally “taking” (killing) endangered species like bull trout, steelhead, and the Oregon Spotted Frog. The meeting had a wealth of information but the shocker for me was an admission by the irrigation districts that they have been badly mismanaging flows in the middle Deschutes.Read More »
Here’s the latest graph of flows in the middle Deschutes below North Dam in Bend near the Riverhouse. On November 26 the river got down to 63.8 cfs. On a relative basis, that’s worse than 20 cfs in the upper Deschutes below Wickiup. Years of discussion and “cooperation” at the Basin Study Work Group between the irrigators, government agencies, and various other groups has made no improvement in how the river is managed. For the second time this year the irrigators have killed the middle Deschutes (visit the prior post for a more detailed discussion of this topic).
Irrigation season has started and once again the middle Deschutes is suffering. As you can see on the Bureau of Reclamation website, the Deschutes River below North Dam (just upstream from the Mt. Washington bridge) is now reduced to 62 cfs. As I argued in this post, recent levels are least as damaging as what happens in the upper Deschutes below Wickiup Reservoir in the winter. The flows should come back up a little later in the spring as the irrigators allow some additional flows but by that time the damage will have been done. The exposed river bottom will kill fish eggs, the aquatic insects that fish eat, and the plants that the insects need. In spite of all the time, effort, and money put into restoration the Deschutes continues to be no more than an irrigation ditch for the benefit of a few irrigators to the detriment of the rest of us.
UPDATE: a reader pointed out to me that my graph only covers the past 2 weeks. If you go to the BoR site (link above) and run the graph for a longer period you will see that the middle Deschutes was running around 800 cfs for most of the winter. 800 cfs to 62 cfs is a better illustration of just how environmentally damaging the beginning of irrigation season is.
While the upper Deschutes has been the focus of late, the middle Deschutes also needs additional flows. Unfortunately, there are no real plans for this. The middle Deschutes is generally defined as the segment from Benham Falls to Lake Billy Chinook and flows in this section are complex. Read More »
