Nicasio Reservoir project prompts flooding concerns
Nicasio residents are urging the Marin Municipal Water District to reconsider a proposal to add storage to the nearby reservoir. Over the past two weeks, residents have told district officials that they fear the project could exacerbate flooding along Nicasio and Halleck creeks, and that the community would see no benefit from the added storage at Nicasio Reservoir. The community uses well water and is not served by the reservoir or the district’s supply. Residents said increased flooding would threaten their properties, the roads, the school and their well water and septic systems. … The proposal calls for modifying the spillway gates at Seeger Dam, which was constructed on Nicasio Creek in 1960 to create the reservoir. … The project would install a 280-foot-long, 4.4-foot-high inflatable rubber gate spanning the spillway crest to increase capacity by about 3,700 acre-feet. The project was selected from several proposals as a short-term and efficient way to increase supply.
