East Bay Municipal Utility District (EBMUD)
The Mokelumne River watershed in the Sierra Nevada is the source of 90% of water to the MBMUD and because of the heavy rains in the fall of 2012 those reservoirs are still two-thirds full. If drought conditions persevere, by March this district may decide on mandatory rationing.
There are still rebates available for lawn conversions and other water saving projects.
MMWD services central and southern Marin. 75% of their water comes from the 21,635 acres of protected watershed on Mt Tamalpais and in the grassy hills of west Marin.
Rainfall from these watersheds flows into seven reservoirs. Their water is treated and filtered before delivery. Current capacity in these reservoirs is .4-40% approximately. 25% water is imported from Sonoma County see report below in their status.
Possible mandatory rationing to be announced end of February.Novato water comes from three sources: 80% Russian River, the rest from Stafford Lake and Recycled water.
Stafford Lake is at 30% of capacity
Sonoma County gets its water from the Russian River. The river is fed from these two sources:
Lake Medocino: at 38% capacity
Lake Sonoma: 67% capacity
At this moment, Solano County is in good shape says Solano County Water Agency General Manager David Okita.
95% of its water is from Lake Berryessa which is 69% full.
The remaining 5% of their water is supplied by the state.
A recent news report has stated that the city's water supply - from Hetch Hetchy is at 70%. Regardless of today's supply, the SFPUC will likely be advising of water restrictions soon.
Ten local reservoirs in the Santa Clara Valley Water District are at 33%. This is 66% of the 20 year average, their spokesman Marty Grimes said.
They have an advantage or abundant ground water, though.
