OBERMEYER HYDRO, Inc. Ideas that Hold Water

Spillway capacity is preserved as the low profile of the OBERMEYER Gate System allows efficient passage of flood flows without any significant increase in flood pond elevation. This prevents dangerous overtopping of dam embankments or flood damage to upstream properties.

In many instances, the most practical method to conform to present spillway capacity standards at an existing dam is to lower the spillway. At sites with inadequate spillway capacity, OBERMEYER Spillway Gates can be used to lower the spillway sill while maintaining or even increasing normal pond elevation. This is a very economical approach for increasing dam safety without sacrificing water storage or power generation.
