Welcome to the Tri-Dam Project
Tri-Dam Project is a partnership between the Oakdale Irrigation

operate and maintain the Beardsley, Donnells and Tulloch projects including
the dams, tunnels, penstocks, power houses, communications systems, and general
offices. These facilities are located on the Middle Fork of the Stanislaus
River in Tuolumne County, California.
The "Upper Works" include Donnells and Beardsley dams, reservoirs,
power houses and appurtenant facilities. The "Lower Works" refer
to the Tulloch development below Jamestown reaching into both Calaveras and

Press Release from the Bureau of Reclamation
April 7, 2015 Update
OID/SSJID Press release regarding New Melones
David Murillo, Bureau of Reclamation
Weekly Update, for week ending April 3, 2015
The water situation continues to be very challenging. As has been publicized throughout the State, the April snow survey results demonstrate the dire situation throughout the region. Governor Brown has now directed mandatory restrictions to be applied throughout the entire state, to target additional water use reductions.
Last week, OID and SSJID announced that a preliminary agreement had been reached with the Bureau of Reclamation and National Marine Fisheries Service on a Temporary Urgency Change Petition (TUCP). The TUCP must be approved by the California State Water Resources Board, and as of today, that approval has not yet been received. The Districts remain hopeful that an agreement can be reached, allowing the prudent use of reservoir waters for people and agricultural uses, while balancing the fisheries releases The posted reservoir schedule remains in effect, at present, and updates will be posted should the schedule be revised. Please continue to watch for updates.
