Don Pedro Dam gates open for first time since 1997
For the first time in 20 years, the controlled spillway gates at the Don Pedro Reservoir opened Monday afternoon.
The outflows from Don Pedro Reservoir were between 18,000 and 20,000 cubic feet per second (cfs), as of 3 p.m. Monday, according to the Stanislaus Consolidated Fire Protection District.
The Turlock Irrigation District said the spillway will be open for at least four days.
It takes approximately 23 hours for the releases from Don Pedro to reach the Ninth Street Bridge at Modesto. The Tuloumne River is expected to peak at 62.9 feet late Tuesday.
When the releases began, the reservoir was at 825 feet in elevation, 5 feet below maximum capacity, according to the California Department of Water Resources.
After flowing from the reservoir, the water will go down the spillway, take a hard left and follow a channel that was cut out in 1997. It will then rejoin the Tuolumne River about a mile downstream.
The controlled spillway hasn’t been used since 1997.
The structural integrity of Don Pedro Dam and its controlled spillways aren’t in question and aren’t a factor in the early release, according to TID.
Residents living downstream of the Don Pedro Reservoir are preparing for flooding as water levels on the Tuolumne River are expected to rise. Mandatory evacuations haven’t been issued, but authorities are starting to advise some people to seek shelter and move to higher ground.
