Can MMWD enlarge the reservoirs to hold more water by raising the dams?
MMWD's water rights are granted by the State of California. The rights specify how much water we can legally divert from our local creeks and store in our reservoirs. As part of these reservoir storage rights, water is also released into the creeks to provide in-stream flows for the fish.


When the district last filed for rights to expand storage in 1980, the result was 15 years of studies and hearings prior to reaching a court-ordered agreement. Since that time, stronger protections have been put in place for endangered coho salmon. Given the water needs for fish and the high volume of water we already divert, it is highly unlikely that MMWD would be granted the necessary approvals to further increase reservoir storage.
