Bingham has a weir that stops all fish. When the pond gate is open they swim up a ladder into the holding ponds and when sorting fish wild are put in a hole in the side wall of the pond which is really a tube slide that puts them back into the East Fork Satsop above the weir. Bingham Cr itself has a weir operated by the science division that also stops the fish. Bingham uses both Bingham Cr and East Fork Satsop water so wild would be inclined to return somewhat with out a weir.
