The purpose of this investigation was threefold: (1) to determine the rate of nutrient accumulation in Beaver Reservoir, (2) to develop a eutrophication model to predict future eutrophication levels, and (3) to identify and isolate the major nutrient contributors of Beaver Reservoir. Stream and reservoir sampling networks were established and monitored for the various forms of soluble nitrogen and phosphorus. A nutrient budget for Beaver Reservoir was determined, and the rate of nutrient accumulation calculated from the nutrient inflow and outflow rates. The major nutrient contributors were based on the various types of runoff. These were ranked according to the amount contributed to total nutrient inflow. Overall algal growth rates for the six Beaver Reservoir sampling stations were developed from a reservoir model equation. Various parameters which influence algal growth were regressed to establish an overall rate equation. Other prediction equations were established for regression for nutrient loadings from major nutrient contributors.
