The Path of Released Water Don Pedro Dam

Spillway Release Path

Normal Release Path

Once the water rejoins the river channel, it continues downstream through the communities of Waterford, Hickman, Ceres and Modesto before eventually joining the San Joaquin River just south of Vernalis. The San Joaquin eventually empties into the delta and out to sea. aa CC l laa vvee rraa ss CC oo uu

The controlled and emergency spillways at Don Pedro send water through an area known as Six Bit Gulch where it rejoins the Tuolumne about 1/2 mile downstream of the Don Pedro Powerhouse. This path takes the water out and away from the main dam structure and safely redeposits it into the river channel.
