The purpose of the project is to decommission two infiltration ponds adjacent to the Russian River to prevent the entrapment of salmonids and reduce aquatic species entrapment in the ponds after flood events. The project consists of decommissioning the ponds by removing two manual valves and re-grading the channels and ponds at a slope of 1% toward the Russian River. Re-grading the channels include the removal of portions of the roads between the channel and ponds. A 1% slope will allow the ponds to fill with water during flood events, but will allow them to drain at the same rate as the receding Russian River.
The project involves maintenance to protect fish and wildlife resources. The project involves filling a previously excavated site with material compatible with the site. The project is being completed as part of the National Marine Fisheries Service's Reasonable and Prudent Measures in the Biological Opinion for Water Supply.
