Water Right Permit Application A033408 and Petition for Change and Instream Flow Dedication for License 10324 (A023120)

This project involves Water Right Permit Application A033408 and a petition for change and instream flow dedication for License 10324, managed by the State Water Resources Control Board, Division of Water Rights. Located on the property of Husch Vineyards, Inc. in Mendocino County, California, the project focuses on the diversion and beneficial use of water from the Navarro River. The scope includes a wet season diversion to offstream storage of up to 12 acre-feet per year at a rate not exceeding 0.218 cubic foot per second from December 15 to March 14. Additionally, the project authorizes direct diversion and diversion to offstream storage of up to 84 acre-feet per year at a rate not exceeding 0.218 cubic foot per second from March 15 to September 1. The petition specifically seeks to change the purpose and place of use for the diverted water while dedicating a portion of it to instream uses to benefit fish populations within the Navarro River. The State Water Resources Control Board has issued a Notice of Exemption, dated November 19, 2025, determining that the project is exempt from the California Environmental Quality Act. This exemption is based on categorical exemptions for existing facilities and small habitat restoration projects, specifically meeting the Class 33 categorical exemption under California Code of Regulations, title 14, section 15333. The Board concluded that the project is expected to have no significant environmental impact. The project is overseen by the Division of Water Rights, with Matthew McCarthy serving as the primary point of contact for environmental inquiries.
