Calaveras Map


The Lower Calaveras River runs through under-served neighborhoods in Stockton; it is vital to farmers, residential and recreational water users.

•It provides critical habitat to threatened fish and wildlife, including threatened Fall Run Chinook Salmon and steelhead.

• Carcass surveys in 2005 and 2006 indicated that 87- 95% of the salmon did not make it to good spawning habitat above Bellota Weir:

2005 total run estimate: 1,150

2006 total run estimate 102

2007 total run estimate: 0

• The Calaveras River is entirely rain fed (no snow melt).

• New Hogan Reservoir, encompassing about 115,000 acres, receives up to 90,000 acre feet of surface water supply from the upper Calaveras and controls water flow on the Lower Calaveras River.

• The four main tributaries below New Hogan Dam are: South Gulch, Indian Creek, Duck Creek and Cosgrove Creek; Cosgrove contributes the most run-off, as much as 8,500 ace feet in some years.

The Friends of the Lower Calaveras River (FLCR) …

• Was formed in 2007 by 30 concerned citizens, and now boasts over 400 members.

• Has 11 partners from local conservation organizations, county and federal agencies.

• Focuses on one of the most dramatically altered, rain fed rivers in California.

• Sponsors 3 annual river clean-up events with over 600 community members taking part.

• Sponsors monthly Riverwalk events, free of charge to the public, for community members to learn about various aspects of the Calaveras River watershed.

• Represents an important part of the overall effort to restore the Lower Calaveras River for the benefit of all -people, fish, and wildlife – who use the river, and to connect the communities in Stockton to this natural area.
