Water Conservation Area 3 (WCA-3) is the largest existing WCA covering a total of 915 square miles within Western Dade and Broward Counties.[1] Lying southwest of WCA-2 and just north of Everglades National Park, WCA-3 is used primarily as an area to receive flood waters from adjacent areas and store them for beneficial municipal, urban, and agricultural uses. It was subdivided into WCA-3A and WCA-3B by way of the L-67 canal and levees as a safeguard against seepage into the aquifer.[2]
