The first real fall-run salmon season on the Trinity in years hit a wall on its lower reach, with adult Chinook fishing closing at 11:59 p.m. on Friday, Oct. 16. The California Department of Fish and Wildlife reported that anglers are projected to reach the 536-fish adult quota for the stretch from the Denny Road Bridge at Hawkins Bar downstream to the Klamath confluence by the end of the day, triggering an automatic closure there. … The Klamath and Trinity are managed as quota fisheries this year, with a combined allowance of roughly 3,200 adult fall-run Chinook spread across different sections of the two rivers. Filling a sub-quota this quickly on the Lower Trinity points to real numbers of fish in the system, which tracks with reports of salmon spawning in the upper Klamath for the first time in a century following the 2024 removal of four dams.
