Physical and mathematical models were used to investigate the mechanics of density-stratified flow within Bay Springs Lake as affected by inflow from the local drainage areas and the divide-cut canal, and to predict the temperature and dissolved oxygen D.O. regimes of the lake immediately upstream of the dam and in releases through the lock. The hydrodynamic phenomena in the lake were greatly influenced by the extremely dynamic nature of the operation of the Bay Springs project and the relatively large quantity of flow from the divide-cut canal. Operation of the lock indicated that a circulation of water within the hypolimnion should occur during certain times of the year. The lake is primarily affected by inflow from the divide-cut canal. Numerical simulations predicted satisfactory temperature and D.O. profiles at the dam. The relatively high withdrawal of the lock intakes, coupled with the large inflow from the divide-cut canal, indicates the proposed project will satisfy water-quality interests.
