More great news about the progress on the other side of the mountains in the broader Klamath-Trinity watershed. Those salmon were impatient to get back to where they belong!

Due to elevated disease prevalence in salmon in the lower river, tomorrow, Aug. 28, the Bureau of Reclamation plans to increase baseflow releases to the Trinity River from 450 cubic feet per second to 1,200 CFS. The increase is in coordination with the Yurok and Hoopa Valley Tribes, the State of California, the U.S. Fish and Wildlife Service, and other partners to encourage migrating adult salmon to find more favorable habitat conditions upriver.

The flow augmentation is anticipated to utilize approximately 35,000 acre-feet of water from Trinity Reservoir, which is currently at 109% of historical average for this date.

During these elevated releases, river levels will rise, and currents will be fast and cold. Visibility in the water may also be impacted as flow inundates banks that have been dry all summer. Members of the public are strongly urged to exercise caution and follow all appropriate safety measures when near or on the river.

Come fly along the newly reconnected cemetery side channel on river right of our channel rehabilitation project currently in Lewiston. Work this summer has reconnected .44 miles of riverine habitat at baseflow and is nearing completion in this area. River recreationists should be aware that the side channel is not a through passageway however it will be accessible by foot once the project is complete.

On Thursday, Aug. 20 the Trinity Management Council will convene in a special meeting from 10 a.m. to 12:30 p.m. to hear the findings from an analysis of factors limiting returns of adult Chinook salmon to the Trinity River watershed. The findings, prepared and presented by Kramer Fish Sciences, will help scientists and managers understand how to improve management actions that are under the purview of the Trinity Management Council and beyond. The meeting will be open to the public.

It's pretty incredible to compare these two shots of this Trinity River valley location. Can you name that mountain ridge in the background?

On-the-ground POV of one of the sites featured in yesterday's drone photos. This is R-1, the upstream-most of the four restored floodplains at the Upper Connor Creek restoration site. It was designed to start getting wet between 600-700 cfs so that it would be wet most of the winter through early summer. The river decided "not good enough" and built its own perennial side channel through the middle of it. The wildlife are really loving this site, including juvenile fish. If you watch carefully, you will see little fish popping clear out of the water like reverse raindrops.

At the end of July we went out to fly the completed Upper Conner Creek channel rehabilitation site located at the Junction City campground river access. Just one year after completion, the former mining sediment terraces are looking much more like a dynamic river and floodplains. Check it out!
