Welcome to the Tri-Dam Project
Tri-Dam Project is a partnership between the Oakdale Irrigation
District and the South San Joaquin Irrigation District. Together they developed,
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
Tri-Dam Project is governed by a joint board of directors composed of the
five member boards of the two Districts. The day to day activities of Tri-Dam
Project and Tri-Dam Power Authority are managed by a General Manager who
reports to the board. The administrative offices of Tri-Dam Project are located
in Strawberry, California.
Weekly Update, for week ending March 20, 2015
No new conditions beyond those presented on March 7, 2015. The 2015 Fill Schedule from the Bureau of Reclamation has been received and is posted below. Conditions along the Stanislaus River Basin remain very dire, with the effects of the fourth dry year and prolonged drought presenting extreme challenges in light of continuing release flows. No additional rain has fallen, and no significant rain is predicted in the near future, thus Tri-Dam continues to be very concerned about reservoir levels during the coming months.
For immediate release - March 11, 2015
