    your part 2 Why does MMWD let the reservoirs spill during a drought Isn t that wasting water The capacity of each reservoir is set by the elevation of the dam which in turn is set by the water rights accorded to MMWD by the State of California see next question Once a reservoir is full any additional water will flow naturally over the dam s spillway We don t have the legal or physical ability to hold on to that water When Lagunitas Bon Tempe and Alpine are full the overflow spills into other district reservoirs downstream Water from Phoenix Kent Nicasio and Soulajule flows into local creeks where it provides many environmental benefits including habitat for endangered coho salmon and other fish and wildlife Thus even water that goes over the spillways is put to good use 3 Can MMWD enlarge the reservoirs to hold more water by raising the dams or dredging the reservoirs 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 4 Have MMWD s reservoirs lost capacity due to sedimentation We recently completed a bathymetric survey of Bon Tempe Reservoir using sonar and laser technologies to map the bottom of the reservoir and determine its current capacity The last study of the reservoir s capacity was conducted when it was built in the late 1940s The 2014 survey found that sedimentation is not a problem in Bon Tempe In fact using modern methods we found the capacity of Bon Tempe is greater than the measured capacity calculated in the 1940s study MMWD plans to perform similar studies on our other primary storage reservoirs Alpine Kent and Nicasio 5 If sedimentation is found to be a problem could the reservoirs be restored to their original capacity through dredging It s possible that MMWD could obtain permission from the state to restore reservoir capacity lost due to sedimentation However removing accumulated sediment would be a challenging and expensive project It would likely require extensive review permitting and mitigation To increase storage capacity by 1 000 acre feet a mere 1 increase over existing storage would require removing 1 6 million cubic yards of sediment To dispose of that much material we would need to find 100 acres of land to pile dirt 10 feet deep Excavation and disposal alone
