The second phase would rehabilitate the three 84-inch roto valves inside the irrigation tunnel and three 84-inch jet valves at the outlet end of the irrigation tunnel. A roto valve is designed to open and close relatively easily, despite high fluid pressure. Jet valves are installed as part of the outlet structure, and decrease the pressure of the water exiting the bottom of the dam, which prevents erosion and scouring. Another part of the project was to evaluate the current condition of inoperable piezometers at the dam and seek bids to repair or replace them.
