Photo shows first prototype tube fish screen during initial field testing at Meamber Ranch. River water is drawn into the pump sump being viewed in the previous picture when tailwater is insufficient to meet Don Meamber's irrigation needs. This screen design works well in the Shasta River during low flow conditions in summer and can be removed from the river after the irrigation season to avoid damage during high flows.
