Description:
This study assessed entrainment rates and effects for important components of the aquatic community in the once-through cooling system of a steam-electric power plant (the Monroe Power Plant), which can draw up to 85 cu m/second of cooling water from Lake Erie (-80%) and the Raisin River (-20%). Phytoplankton, periphyton, zooplankton, ichthyoplankton, and community metabolism were sampled bimonthly from November 1972 through September 1975. Sampling was conducted at fixed locations in the intake region, discharge canal, thermal plume and the lake-source waters. Concentrations of chloride, dissolved and total solids were used to trace water masses and their associated nutrient and plankton concentrations. At temperatures above 15C in the discharge canal, photosynthesis was depressed and community respiration was accelemprated. Algal abundance increased slightly as green and blue-green algae increased more than other taxa during passage, but algal diversity remained basically unchanged.
