The influence of the thermal outfall jets from the Blount Street Power Station (Madison, Wisconsin) on the distribution and abundance of zooplankton in Lake Monona was studied. Sampling showed that Diaptomus, Daphnia, and cyclopoid copepods were two to seven times more abundant in the water near the outfalls than in the control areas. Zooplankton density maxima occurred in or very near the discharge currents suggesting that the animals were being brought into the system rather than being produced in situ. When the plant shut down one of its two jets during low power load, high outfall zooplankton densities fell to normal control area values within several hours. None of the species avoided the intakes. (Author)
