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.
