3. 60" Jet -Flow Gate
One 60" Jet -Flow Gate is installed in the outlet works control house. The gate is intended to
be used only for emergency evacuation. The hydraulic power unit, located in the control
house, is used to control the gate from the ACP or at the gate. The jet -flow gate consists of
fabricated steel bodies, a gate leaf, bonnet cover, and oil- operated hydraulic hoist. The
hydraulic hoist is used to move the leaf that slides and seals on bronze seats and a bronze
seal ring. The hydraulic hoist has a 20" diameter bore and a 5' -3" stroke. The gate was
operated and tested as part of the 2012 CR.

4. Hydraulic Controls for Guard Gate and Jet Flow Gate
One hydraulic power unit (HPU), located in the control house, is used to control the 4' x 6'
guard gate and 60" diameter jet -flow gate. The unit has two separate oil pumps and
motors, each of which are designed to independently operate the gates.
The guard gate is designed to operate under maximum reservoir head of 250 feet and a
maximum cylinder pressure of 2,000 psi, and the jet -flow gate is designed to operate under
maximum reservoir head of 250 feet and a maximum cylinder pressure of 1,000 psi. All HPU
functions have been tested in the presence of the Association and Reclamation.
