THE FOLLOWING IS A PRESS RELEASE FROM THE OREGON DEPARTMENT OF FISH AND WILDLIFE
The Columbia River around the mouth of the Deschutes River will close to all fishing, including catch-and-release, beginning at 12:01 a.m. on Thursday, Aug. 9 in order to protect summer steelhead that may be utilizing the cooler water provided by this tributary.
At their Aug. 3 meeting, the Oregon Fish and Wildlife Commission directed ODFW staff to amend fishing regulations for the Columbia River near the Deschutes and in the lower Deschutes from the mouth upstream to Moody Rapids. The direction included closing this area to all fishing until river temperatures have stabilized below 68 F. ODFW staff will continue to monitor river temperatures and run sizes throughout the fall to determine when the area can be reopened. This is unlikely to occur prior to late-September.
The closed areas will be:
All waters south of a straight line projecting from the flashing red USCG light #2 upstream to the lower South Channel Range B marker located approximately 3/4-mile upstream of the mouth of the Deschutes;
The lower Deschutes River from the mouth upstream to markers placed on the downstream end of Moody Rapids.
Concerns about the vulnerability of fish to fishing pressure in the mouths of some tributaries of the Columbia River were sparked by the historically low returns of Snake River-bound summer steelhead in 2017. At that time the states of Oregon and Washington adopted unprecedented restrictions to several fisheries to reduce mortality on these fish.
In June 2018, ODFW staff outlined for the Commission a plan to take a comprehensive look at potential thermal sanctuaries throughout the Columbia River. That review process will include a series of public meetings in the fall of 2018 followed by rulemaking in early 2019.
