Abstract | To develop additional information on the effect of point and non-point sources of wastes and on the trophic condition of the three lakes, EPA conducted an investigation of Grand, Shadow Mountain, and Granby Lakes. The study, conducted in June and repeated again in September, 1974, concentrated on (1) the determination of the existing nutrient level in each of the lakes; (2) the determination of the existing organic and nutrient loadings from point and non-point sources; and (3) the determination of the probable consequences of increased nutrient levels in the three lakes as regards nuisance algal growth. Sampling was conducted at 71 locations throughout the study area. |
