The increase in discharge is necessary to volitionally push the smolts out into the river to reduce the risk of predation. Consultation: Ramping rate schedule below was agreed upon in Feb 3rd meeting of Sonoma Water staff with CDFW and National Marine Fisheries Service staff.

Russian River Fisheries Monitoring Report on 2/18/21: Report on 2/18/21: Sonoma Water operates a fish counting station at a seasonal dam on the Russian River near the town of Forestville, CA. The Mirabel Dam video monitoring station closed for the season on January 23, 2021, but Sonoma Water continues to review video that was collected earlier in the season. Video is recorded at the east and west fish ladders. The counts below reflect totals completed for the full period of operation for the east fish ladder and up to January 11th for the west fish ladder. Surveys were conducted at five sites in the Upper Russian River to collect information on spawning salmonids and their redds. However, water visibility was too poor to observe salmonids or redds. Visibility ranged from 1.0 ft to 1.6 feet. During this time spawning was observed in Dry Creek.
