Upper Great Miami River Watershed

Final Impact Forecasts

Comparison of End Results (After 50 Years)

By comparing the current status of the Upper Great Miami River watershed with the results of the three proposed scenarios at the end of 50 years, it is evident that although all scenarios will experience some degradation, there are significantly different outcomes between scenarios 1 and 2 (or 3). It is obvious that unregulated growth provides no protection against water quality decline throughout the watershed. In this watershed, regulations are able to reduce the severity of the water quality decline and are responsible for even increasing the quality in one area.
