|Region||Lower Feather Watershed|
The Sutter Basin is a 264 sq mi (680 km2) 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) and uses irrigation from the Thermalito Afterbay's Sutter-Butte Canal. The Feather River and the Sutter By-Pass are the basin's east and southwest borders.
The Sutter By-Pass is a leveed channel of the Lower Sacramento Valley Flood-Control System along the southwest portion of the Sutter Basin. The by-pass allows channeling of escapement flow from the Tisdale Weir near the Sutter Buttes to the Feather River at . During Sacramento River flows of >23,000 cu ft/s (650 m3/s), Sacramento overflow tops the 53 ft (16 m) Tisdale Weir and flows via the Sutter By-Pass to Feather River mile 7:3–55 (the west levee of the bypass continues along the Feather River to the Sacramento River).
The bypass also receives similar Sacramento escapement flow from the Colusa Weir, 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 By-Pass, The bypass includes 3.24 sq mi (8.4 km2) of the Sutter National Wildlife Refuge, which is part of California's ~5.00 sq mi (12.9 km2) Sutter Bypass Wildlife Area.

NOTE: Pumpback returns Feather River water back to Lake Oroville during off-peak periods when external California Edison Company (SCE) power is inexpensive, allowing subsequent hydroelectric generation (6-7% of Hyatt total) during peak (higher price) periods.

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
