Abstract |
The National Field Investigations Center-Denver of the Environmental Protection Agency evaluated the American Falls, Brownlee, Milner and Minidoka Reservoirs in the Snake River Basin, and determined the concentrations of total phosphorus and inorganic nitrogen for algal bloom conditions and maximum algal growth. The growth limiting nutrient for each of the reservoirs during the different seasons of the year was determined. Aerial infrared photographs documented the algal blooms and effluent additions to the receiving waters. Recommendations were made as to how to solve the algal growth problem which included reducing the total phosphorus from municipal, agricultural and industrial sources, and better management of irrigation waters to reduce soil erosion. |
