A one~dimensionallake water quality model, MINLAKE98, was calibrated to simulate water
temperature, dissolved oxygen, total phosphorus and chlorophyll~a in Lake McCarrons, a lake
with 0.33 km2 surface area and 17.3 m maximum depth located in Roseville, MN. To improve
the summer water quality of the lake, several management options have been considered. The
potential effects of five of these management options were simulated using the model calibrated
for 1995 and 1996 inflow and weather conditions. The model projected that total inflow
diversion during the summer, phosphorus treatment of the inflow during the summer and
reduction of phosphorus release from the anoxic sediments during the summer have all only a
minor effect on phytoplankton standing crops in the lake. Phosphorus removal (precipitation)
after ice~out (before the growing season) and artificial deepening of the surface mixed layer to 8
m or more were projected to give a significant (more than 50%) reduction in phytoplankton
