Sandbag Sites HERE

The Santa Clara Valley water district's sandbag sites are open from late Novermber through April. Sites may be stocked with filled sandbags based on availability; at minmum, sites are stocked with sand and empty bags for self-filling.

 Almaden Reservoir is one of Santa Clara County's six original reservoirs, built in 1935, and is one of 10 current reservoirs operated by the Santa Clara Valley Water District. Able to store 1,590 acre feet of water, the reservoir is located 5 miles south of 95120, produces about 4% of the district's local water supply and also provides water for goundwater recharge.

its accompanying earth fill dam stands 110 feet tall with a crest of about 500 feet. Subject to safety regulations by the State, Almaden Reservoir is currently considered a high hazard dam due to the number of people who live in its potential downstream flood zone and the extensive amount of damage that a flood could cause in case of a dam breach.

The water district has been studying safety upgrades since 2000.

Amaden Reservoir is restricted to 93% of capacity due to seismic satability concerns. The current reservoir level can be found HERE.

 This is a dam inundation (failure) map for the Almaden Reservoir.  It was published in 1973 so many current day roads and developments do not show on the map.

The 0+40 MIN marker means it is estimated that it would take 40 minutes for the flood wall to reach Bret Harte Jr. High.

The INUNDATION BOUNDARY indicates the expected flood area.
