OBERMEYER HYDRO, Inc. Ideas that Hold Water

 
Extra head, provided by OBERMEYER gates, results in increased power production by maintaining maximum allowable pond elevations at all times. Although head can be increased temporarily by use of flashboards, our gates offer many advantages:
 
The 1 to 3 foot margins typically required to cause failure of flashboards cause unnecessary upstream flooding under high flow conditions. OBERMEYER Spillway Gates accurately maintain the optimum pond level for increased power generation while eliminating unnecessary upstream flooding.
 
Unlike flashboards, OBERMEYER Spilllway Gates can be raised immediately as flows recede. This results in greatly increased power production when high flows are available and high tailwater elevations would otherwise reduce power production.
 
OBERMEYER Spillway Gates allow spillway flows to be directed in the most beneficial manner. At many facilities, power plant tailwater elevations may be minimized, and power output increased, by directing spillway flows away from the power plant. By using independently controlled sections of OBERMEYER Spillway Gate this can be easily accomplished. Flows may be directed to provide attraction water for fish ladders, and debris and ice may be passed over the spillway in such a way that power generation facilities are not adversely affected.
 
The controlled pond level provided by the OBERMEYER Spillway Gate System allows formation of stable ice cover, thus reducing the formation of fragile ice that otherwise obstructs intake trash screen.
