Five replicate mapping studies were conducted at the Point Beach Nuclear Plant and the Waukegan Power Plant between April and September. Mapping runs were made in the plume areas to compare fish density and distribution in heated vs. unheated regions. Although there were no striking trends in fish distribution relative to bottom depth and depth stratum, there were differences between dates and locations, reflecting differential responses with time, species, and discharge type. Temperature orientation by fish was significantly different between plume and reference areas. Reference area fish were often most concentrated in the warmest ambient water, while plume fish were most concentrated at intermediate plume temperatures. (HLW)
