The Bureau of Reclamation plans to stop all water flowing out of Crane Prairie Reservoir for up to 8 hours later this month, tentatively on October 30th, de-watering the Deschutes River for about 1.5 miles down to Wickiup Reservoir. This is to perform an inspection of the dam. It will also kill a section of the river that is important for spawning and holds some nice fish. See the photo above of my friend Jake with a nice brown trout from this stretch.Read More »
I have written about the “Blob” in the past (most recently, here and here). It is the much higher ocean temperatures in the North Pacific which have disrupted food chains and imperiled many historic fish runs. An argument can be made that ocean heating is currently the most worrisome of all the conditions leading to the drastic declines in salmon and steelhead populations in the Pacific Northwest. Here is the first part of a three-part article from NOAA discussing the Blob. Below is a graphic showing the re-emergence of the Blob this year. It could be worse than the original one, it already has more area of the most extreme warming, and is still forming.
Today the Bend Bulletin printed a response to my recent letter from Kurt Miller, the Executive Director of Northwest RiverPartners, a group that lobbies for hydroelectric facilities on the Columbia River. Predictably, Mr. Miller takes issue with my inclusion of hydro power dams in the list of reasons that anadromous fish populations are collapsing in the Columbia River Basin.Read More »
Yesterday, the Bend Bulletin printed a guest column I wrote on the grim outlook for steelhead and salmon in the Columbia Basin (including the Deschutes River). Above is a graphic that illustrates the problem. Here’s a NY Times article on the same topic. Whether some of these fish have 10 years left as I have read in some places, or 20 as reported in the NY Times, it is not a hopeful picture.
George Wuerthner is one of the most interesting ecologists and activists I have met, and certainly the most prolific writer. He has written dozens of books and many more articles on wildfire, predators, and the environmental impact of ranching, along with water and fishery issues. His views are often controversial, especially regarding fire, but compelling when carefully considered. In short, George believes that forest thinning does not help catastrophic wildfire control. He argues we should focus on creating fire resistant buildings, establishing defensible borders, and leaving forests alone. The explanation for this is beyond the scope of this post, but here’s a video he sent me on the beneficial nature of fire in stream and river systems. It’s worth a quick view.
Oregon Public Broadcasting reported yesterday that another warm water “blob” is forming off the Pacific Coast. This blob is likely to be as large as the last one which collapsed much of the food web that many cold water marine species rely on. “Scientists expect the heat wave to hurt salmon populations and the fisheries that depend on them.” Of course, chinook salmon and steelhead have not recovered from the last blob and returns this year in the Columbia basin (including the Deschutes) are at perilously low levels.
While the operation of the hydro power dams on the Columbia and Snake Rivers is not directly a Central Oregon issue, it certainly impacts us as anglers. Below is a good overview of something I’m sure you have heard about before, upper Columbia basin salmon (and steelhead) are on the path to extinction. Lesser known is that the Bonneville Power Administration is going broke.Read More »
