The zooplankton community of Houston Reservoir.
A one year study of the limnetic net zooplankton community of eutrophic Houston Reservoir, a warm monomictic reservoir located in southeastern Texs, was conducted from October, 1984 to September, 1985. Samples were taken from seven sites using a submersible plankton pump. The number of organisms per liter and the species composition were determined for each sample. Houston Reservoir had an annual numerical density of 45.4 org/L with the greatest density in the late summer and early fall. The zooplankton community consisted of 72% Rotifera, 19% Copepoda, 7% Cladocera, and 2% Culicidae. The yearly mean species diversity was 2.50. By examining the zooplankton data, it was determined that the West Fork region of the reservoir was the most eutrophic.
