ABSTRACT:
A fish-excluding, self cleaning screen forming at least part of the boundary between a body of water such as a stream, and a bay from which water is to be withdrawn. On the bay side of the screen is a hub with a plurality of rotating wands that discharge water against the bay side of the screen to flush screen apertures and provide a periodic variation in flow through the screen to discourage passage of fish. Optional brushes may periodically brush the bay side of the screen to assist in cleaning the apertures.
