A study was developed for the Morrow Plant to investigate the potential for turbine related mortality of entrained fish. Morrow Lake supports a small sport fishery, mainly for smallmouth bass, yellow perch, and panfish (Bohr and Liston, 1987). Numerous panfish along with small numbers of large gamefish (smallmouth bass, largemouth bass, and northern pike) were found to escape Morrow Lake at the spillway prior to powerhouse installation (Liston et al. , 1986). Hence, the potential for turbine entrainment does exist.
