The Sutter Basin is a 264 sq mi (680 km2) [1] area of the Sacramento Valley in the U.S. state of California, and is part of the Feather River drainage basin. The basin includes the Sutter Basin Fire Protection District of ~127 sq mi (330 km2) [2] and uses irrigation from the Thermalito Afterbay's Sutter-Butte Canal. [3] The Feather River and the Sutter By-Pass are the basin's east and southwest borders.
The Sutter Bypass is a leveed channel of the Lower Sacramento Valley Flood-Control System along the southwest portion of the Sutter Basin. [4] The bypass allows channeling of escapement flow from the Tisdale Weir near the Sutter Buttes to the Feather River at 38°53′08″N 121°36′52″W / 38.885421°N 121.614532°W. During Sacramento River flows of >23,000 cu ft/s (650 m3/s), Sacramento overflow tops the 53 ft (16 m) Tisdale Weir [5] and flows via the Sutter Bypass [6] [7] to Feather River mile 7 [8]: 3–55 (the west levee of the bypass continues along the Feather River to the Sacramento River). [9]
The bypass also receives similar Sacramento escapement flow from the Colusa Weir, [9] and the Snake River, Gilsizer Slough, Wadsworth Canal, and other west side watercourses of the Lower Feather Watershed also drain to the Feather River via the Sutter Bypass, [10] The bypass includes 3.24 sq mi (8.4 km2) of the Sutter National Wildlife Refuge, [11] which is part of California's ~5.00 sq mi (12.9 km2) Sutter Bypass Wildlife Area. [12]
A large volume of the sediments from the Feather River have been permanently deposited in the lower 13 km of Sutter Bypass with which that river is coincident and a large secondary delta has been built up at the northerly end
The Bypass starts north of Pass Road, westerly of the Sutter Buttes and generally goes in a south-southeast direction for about 27 miles
Habitat: 2,591 acres comprised of seasonal marsh, permanent ponds, and uplands.
About 80 percent of the refuge is located in the Sutter Bypass
