Tulelake Irrigation District Infrastructure Modernization Project

The Tulelake Irrigation District Infrastructure Modernization Project is a presolicitation initiative led by the USDA Natural Resources Conservation Service under the Watershed Protection and Flood Prevention Act. Located in Tulelake, California, the project aims to enhance agricultural water management, energy efficiency, and delivery reliability for 924 patron accounts as well as the Tule Lake and Lower Klamath National Wildlife Refuges. The preferred modernization alternative involves upgrading pumps and motors at 28 locations, implementing variable frequency drives, and installing SCADA and automation equipment across 74 sites. These improvements are designed to reduce operational spills and maintenance costs while ensuring minimal ground disturbance by remaining within existing rights-of-way. The total estimated cost for the project is 16,302,000 dollars, with 12,533,000 dollars requested through PL 83-566 funding. A Draft Watershed Plan-Environmental Assessment was prepared in September 2026 to fulfill NEPA requirements, concluding that an environmental impact statement is not necessary. A public review period for the assessment was scheduled from October 1 to October 31, 2026. Coordination for the project involves multiple agencies, including the USDA, the U.S. Fish and Wildlife Service, and the Bureau of Reclamation.
