The Antelope Creek watershed is located in the Lassen National Forest in Tehama County. The creek originates at an elevation of around 6,800 feet and flows southwest from the Cascade Mountains into the Sacramento River just southeast of the town of Red Bluff. The Antelope Creek drainage encompasses approximately 123 square miles. Antelope Creek provides approximately 30 miles of anadromous fish habitat from its confluence with the Sacramento River. Approximately half of the land in the watershed is privately operated for agricultural and timber production, which supports the local economies. Antelope Creek is also commonly used for recreational activities. These include camping, hiking, hunting, fishing, and wildlife viewing. The Antelope Creek has historically been home to significant populations of spring-run Chinook salmon and steelhead trout, both of which have had declining populations in the past decade. Due to high water temperatures and low water levels, these habitats that are ideal for salmon spawning have become inadequate.
Spring run Chinook salmon in the Antelope Creek watershed are state and federally listed as threatened. Fall run Chinook salmon are federally listed as a species of concern. Steelhead are federally listed as threatened. Preventing the extinction of salmon and steelhead requires restoration of priority habitat conditions (listed in the Snapshot Restoration webpage) and consistent, funded monitoring of these fish populations.
