ABSTRACT:
A water control flash gate board uses a torsion spring to bias it in a upright water holding position. When the pressure on the upstream side of the gate board is sufficient to overcome the force of the torsion spring, the gate board will pivot towards a lower water releasing position. A resilient gasket is used along the lower end of the water gate board in order to prevent jamming of the board by debris. A plurality of identically constructed gate board assemblies may be arranged adjacent each other with lap gaskets positioned in between for preventing leakage.
