Water Supply Department); WS-22; Title from PDF title screen (viewed on September 28, 2009).; "December 2007."; The South Florida Water Management District (SFWMD or District) Water Supply Department participated in this project to support the SFWMD Hydrologic & Environmental Systems Modeling (HESM) Department, and to help quantify the interaction between surface water and groundwater near the C-2 Canal in Miami-Dade County, Florida. The HESM Department requested field measurements along the C-2 Canal near the Southwest, Alexander Orr, and Snapper Creek wellfields to improve the calibration of the SFWMM and the NSM in Miami-Dade County. The investigation focused on trying to quantify the freshwater flow to Biscayne Bay that is being intercepted in the C-2 Canal by pumping from the Snapper Creek, Alexander Orr, and Southwest wellfields. The investigation combined data from different sources to help meet its goals: groundwater levels, surface water levels, wellfield withdrawal data, and stream gauging data.
