The effects of heated water discharge on zooplankton in a 4,500 acre Missouri reservoir

Technical Report ·
OSTI ID:7304805
Standing crops, species composition and species diversity of zooplankton were compared between two arms of a reservoir; the Hotwater Arm was thermally loaded while the Control Arm was under ambient temperature. Chlorophyll a in the two Arms was compared. Larval copepods and cladocerans were more abundant in the Hotwater Arm and rotifers were more abundant in the Control Arm. Species composition, and species diversity were similar in the two Arms. Population pulses were generally synchronous between Arms. There were little differences in chlorophyll a between Arms with the exception of a greater content in the Control Arm during summer. The heated water did not drastically reduce the abundance of zooplankton.
