An apparatus is disclosed for controlling water flow into a reservoir such as a farm pond ( 100 ) to prevent silting of the pond due to sediment deposits during heavy rains. A gate assembly ( 10 ) has a reservoir gate ( 12 ) to let water into the pond when the water is clear and block water flow into the reservoir when the water is sediment laden. The assembly ( 10 ) also has a diverter gate ( 14 ) which opens to allow the turbid flow to flow around the pond in a diverter channel ( 104 ) The gates work in opposite directions so that the water flow is either permitted into the reservoir or diverted around the pond in the diverter channel. A turbidity detector ( 50 ) upstream of the gate assembly senses the turbidity of the water to control the gate assembly. The apparatus is preferably powered by a battery recharged by a solar cell. The battery can be buried underground to resist overheating of the battery.
