Abstract
An investigation of the phytoplankton population structure, primarily productivity and the concentrations of the nutrients nitrate and phosphate was conducted in Elephant Butte Reservoir, New Mexico. Diversity and redundancy indexes were computed using counts obtained for 70 phytoplankton species identified. Significant correlations of diversity with temperature, productivity, and algal number were obtained while diversity was negatively correlated with depth and storage. The nitrate concentration increased as storage decreased and the phosphate concentration increased with temperature. These correlations along with the high productivity during the warmer months when storage is decreasing indicate the need for maintainence of a minimum pool size to avoid possible algal blooms.
