Summary
A lowering of the water level on Murphy Flowage during the winters of 1967-68 and 1968-69 resulted in a significant reduction in the relative abundance and acreage of aquatic vegetation. Before the drawdown approximately 75 acres (42%of the flowage) were covered by plants to the extent that fishing was almost impossible in these areas from June through the summer. After two overwinter drawdowns 60 of the 75 acres was [sic] still open to fishing.
