Obermeyer Hydro - Water Storage

Obermeyer Spillway Gates allow increased water storage capacity at new or existing reservoirs with little or no decrease in spillway capacity. In the case of legacy spillways recently determined to have inadequate flood flow capacity, the spillway invert may be lowered to provide the required flood flow capacity while Obermeyer gates are installed to provide increased storage capacity and increased reservoir yield. This avoids the usual compromise between adequate spillway capacity to accommodate floods, and desired water storage capacity. Adding capacity to existing reservoirs by installing Obermeyer Spillway Gates also eliminates the political and financial hurdles and delays which the construction of new reservoirs may entail. Installation of Obermeyer gates for spillway control allows cost effective increases in useful storage capacity on a short timetable.

Obermeyer Hydro - Fish Passage and Environmental Mitigation

The Obermeyer Spillway Gate System may be configured for independent operation of various gate sections. This allows fish-way attraction flows from the spillway, to be directed to fish ladders with a minimum amount of water. Adjustable fish ladders can be constructed from a series of Obermeyer gates. Controlled pond level can prevent the sudden drowning of water fowl nests which often occur when flashboards are replaced. A stable water level and shoreline enhances recreational use and improves aesthetics. Boards, nails, wire, plastic sheet, and roofing paper that are typically used for flashboard construction are kept out of the rivers. Hydraulic oil required to operate other types of gates is not used.
