The Arroyo Canal and Sack Dam Improvements Project, like the Mendota Pool Bypass and Reach 2B Project, is integral to restoring spring-run Chinook salmon to the San Joaquin River. This project implements two of the highest priority projects identified in the 2006 Settlement: fish passage around Sack Dam and a fish screen on the Arroyo Canal to prevent entrainment of juvenile Chinook salmon in the canal. This project is necessary in order to allow salmon to freely move up and down the river to complete their lifecycle (downriver to the ocean and upriver to spawn). The project furthers the Department of the Interior’s efforts to restore Chinook salmon and other fish to the San Joaquin River and is authorized in the San Joaquin River Restoration Settlement Act (P.L. 111-11). Arroyo Canal and Sack Dam are owned and operated by Henry Miller Reclamation District #2131.
The dam and canal are the sole diversion and conveyance facilities for the reclamation district and provide agricultural water supply to approximately 47,000 acres of farmland in the San Joaquin Valley along with conveyance of water supply to Federal and State wildlife refuges and private duck clubs.
