Abstract: Previous HitWaterNext Hit Supply Planning in Northern Florida

John Herbert1

Abstract

Florida is blessed with abundant rainfall averaging between 47 and 53 inches annually, the prolific Floridan Aquifer, and more first magnitude springs than any other place on earth. It is against backdrop that the 1971 Florida Legislature established Florida's utopian Previous HitwaterNext Hit policy: to "provide sufficient Previous HitwaterNext Hit for all existing and future reasonable-beneficial uses ... while providing sufficient Previous HitwaterNext Hit for natural systems." In 1972, the Florida Legislature established five Previous HitwaterNext Hit management districts that are charged with implementing Florida's Previous HitwaterNext Hit policy—largely through the issuance of permits for groundwater extraction.

Groundwater levels of the Upper Floridan Aquifer have declined significantly during the past 75 years. Almost all of the Saint Johns River Previous HitWaterNext Hit Management District and approximately 35% of the Suwannee River Previous HitWaterNext Hit Management District meet the definition of "Previous HitWaterNext Hit Resource Caution Area"—an area where existing sources of Previous HitwaterNext Hit are not adequate to satisfy future Previous HitwaterNext Hit demands and sustain Previous HitwaterNext Hit resources within the 20-year planning horizon.

The Districts have finally recognized that the Floridan Aquifer is at or is very near the sustainable limit of production and that future demand must be met through alternative Previous HitwaterNext Hit sources if we are to avoid unacceptable harm to wetlands, lakes, and springs.

This presentation will look at examples of high-profile Previous HitwaterNext Hit bodies in distress (Silver Springs Group, Lake Geneva, and Lake Brooklyn). We will then look at the efforts of the Districts individually—and cooperatively through the North Florida Regional Previous HitWaterNext Hit Supply Partnership—to develop a regional Previous HitwaterNext Hit supply plan that will provide for all demands over the 20-year planning horizon. Aspects covered include developing protective minimum flows and levels (MFL), developing MFL Prevention and Recovery Strategies, establishing a regional groundwater model that predicts responses to stresses, and identifying alternative Previous HitwaterTop supply sources—including residential conservation and agricultural best management practices.
