Phoenix Lake Integrated Regional Water Management Retrofit Project

active

The study that evaluated what improvements are needed to the dam concluded that the cost and schedule of the improvements would not meet the requirements of the Proposition 1E grant. We completed the feasibility assessment phase for the project and in 2018 determined it to be infeasible within the project constraints, timeline and budget. Studies prepared include: Phoenix Lake is owned and operated as a water supply reservoir by the Marin Municipal Water District. It is open to the public for hiking, mountain biking, fishing, and other recreational uses. The Phoenix Lake Integrated Regional Watershed Management (IRWM) Retrofit project would modify the reservoir to allow it to serve as a detention basin. This would reduce downstream flood risk in lower Ross Valley resulting from creek overflow during storms. Other related benefits include:
