Kopta Slough Flood Damage Reduction and Habitat Restoration Project

The Kopta Slough Flood Damage Reduction and Habitat Restoration Project (the Project) is located on the Sacramento River in Tehama County between River Mile 218 and 223. The Tehama County Highway A9 Bridge (Woodson Bridge) bisects the lower portion of the Project area (see map below). The goals of the Project are:

1. Provide flood damage reduction benefits through reduced bank erosion to protect public resources

2. Provide mitigation credits for projects on State-maintained Central Valley Flood Control facilities

3. Provide ecosystem benefits through the restoration of natural fluvial and floodplain processes

4. Establish long term public ownership of the Kopta Slough property to protect public trust resources and expand recreational opportunities. (see project description for more detail.)
