Endangered and Threatened Wildlife and Plants; 12-Month Finding and Proposed Rule To Revise Critical Habitat Designation for Southern California Steelhead

What it does

We, NMFS, announce a 12-month finding on a petition to revise the critical habitat designation under the Endangered Species Act (ESA) for the Southern California steelhead (Oncorhynchus mykiss) distinct population segment (DPS). The petition from the United Water Conservation District (UWCD) requests the removal of an approximately 9-mile (14.5-kilometer (km)) stream reach from the confluence of Hopper Creek and the Santa Clara River to the face of Santa Felicia Dam. Based on our review of the best scientific and commercial data available, we find that the petitioned action to remove this reach from the critical habitat designation is warranted. Consequently, we are proposing to remove this reach from the critical habitat designation for Southern California steelhead.
