In support of the Bay County hydrologic study, ATM developed a set of computer models that were used as planning tools for the protection of Deer Point Reservoir, a significant public water supply in Florida panhandle. The models utilized were the USGS PART algorithm, the Watershed Management Model (WMM), and the USACE BATHTUB model. The models were calibrated using flow and water quality observations collected at various watershed locations by the Northwest Florida Water Management District. Through the application of the models, ATM determined a set of recommended water quality targets and recommended development standards for the Deer Point Reservoir watershed. Future land use scenarios for the watershed were also conducted to estimate the effects of projected short-term and long-term build-out. Services included hydrologic model development, water quality target recommendations, and watershed development standards recommendations.
