The Little Shasta River is located in Siskiyou County, California. It is one of the primary tributaries of the Shasta River, a major producer of anadromous salmonids in the Klamath system. The Little Shasta River flows westward from the Cascade Range through a steep canyon section onto a relatively low gradient plain prior to its confluence with the Shasta River.

The Klamath Act established the Klamath Restoration Program, a 20_year fishery restoration program, to restore anadromous fish populations and habitat in the Klamath River Basin. An advisory committee, the Klamath River Basin Fisheries Task Force, developed a Long Range Plan to provide guidance in planning and implementing the Restoration Program. Another advisory committee, the Klamath Fishery Management Council, developed a long_term plan for making recommendations on managing harvest of the Klamath River anadromous fisheries. This project is consistent with these plans.

This project will remove of a rock dam in the Little Shasta River and replace it with a concrete structure to allow fish passage. The concrete structure will be a sill, fitted with steel "A" frames to support flash boards approximately 2 ft. high. The structure will accommodate a dedicated fishway designed to ensure passage for all life stages of salmonids. The second component of the project is to install a fish screen that excludes juvenile fish attempting to emigrate to the sea from the diversion ditch.
