I have read many of the substantial comments on the Draft Deschutes Basin Habitat Conservation Plan and associated Draft Environmental Impact Statement. The comments from the Confederated Tribes of Warm Springs illustrate just how tangled an issue this is. Like many others, the Tribes are extremely critical of the draft HCP and EIS, but in a unique way. While most critical comments ask for more water more quickly in the upper Deschutes in the winter, the Tribes want LESS water than proposed. Keep reading to understand why.Read More »
While the winter has started out somewhat dry in Central Oregon, things look good for the Crooked River this winter. Prineville Reservoir was not drawn down to very low levels over the summer and is currently 57% full. The majority of that is “fish water”, meaning it is not earmarked for irrigation use, and can be released for fish and wildlife. 93 cfs is currently being let out into the Crooked, which provides reasonable habitat for fish, and this amount should be maintained throughout the winter. Some fish water may even be left over. Of course, higher flows will likely occur if the reservoir completely fills over the winter. So, right now it looks like next spring and summer could be good for fishing on the Crooked.
The new Opal Springs fish ladder became operational on Nov. 15 and an automated fish detection system was installed 4 days later. In the first 13 days (11/19 to 12/1) 23 trout, 28 whitefish, and 3 steelhead have been counted. That’s an excellent start.
For over 20 years a wide range of companies, organizations, agencies, and individuals have been working on the reintroduction of steelhead and salmon into the upper Deschutes Basin above Lake Billy Chinook. This includes the middle Deschutes, the Crooked River, the Metolius Rivers, and their tributaries.
To the surprise of fish biologists who had anticipated that Whychus Creek and the Metolius Rivers would be the primary destinations, the great majority of the returning steelhead and Chinook salmon have attempted to head up the Crooked River to spawn. The overwhelming preference for the Crooked has been the case every year there have been anadromous fish returns. Unfortunately, until last week a dam at the bottom of the Crooked River had largely blocked upstream passage for these returning anadromous fish. Read More »
Last June, Portland General Electric released a comprehensive, multiyear water quality study of Lake Billy Chinook, the rivers that supply it, and the lower Deschutes River into which water is released. Among other things, the report showed that the Crooked River contains significant amounts of pollution. This pollution combined with sunlight generates suspended algae on the surface of Lake Billy Chinook which is subsequently released into Lake Simtutus and then the lower Deschutes River. Algae blooms are increasing in occurrence, leading the Oregon Health Authority to warn last June that “harmful algae blooms” could “routinely develop in the lake”.
One of the shortcomings in the Habitat Conservation Plan is lack of adequate consideration for water quality. Clearly, high temperatures and pollution can have adverse impacts on fish and the aquatic environment, including mortality (“take”). Irrigation return flows are “covered activities” but the HCP does not adequately examine impacts on water quality from agricultural runoff or provide for minimum standards in covered waterways.Read More »
