Patent ID: 6884001

Claim:
An apparatus for controlling rain water flow in an open main channel to a farm pond, comprising: a gate assembly having a reservoir gate moveable between an open position to permit water flow from the open main channel into the farm pond and a closed position to prevent water flow from the open main channel into the farm pond and a diverter gate moveable between an open position to permit water flow from the open main channel into a diverter channel not connected to the farm pond and a closed position to prevent water flow from the open main channel into the diverter channel, the reservoir gate and the diverter gate being in opposite positions; and a turbidity detector positioned in the open main channel upstream of the gate assembly to detect the quantity of debris in the water flow, the gate assembly moving the reservoir gate to the closed position and the diverter gate to the open position when the turbidity detector detects debris exceeding a predetermined limit.
