9 Fiure 8: September 2013 Lake Levels SRWMD lakes react differently to climatic chanes dependin on their location in the landscape. Some lakes, in particular ones in the eastern part of the District, are embedded in a surficial or intermediate aquifer over relatively impermeable clay deposits. These lakes rise and fall accordin to local rainfall and surface runoff. They retain water durin severe drouhts since most losses occur from evaporation. Other lakes, such as Governor Hill and Waters Lake, have porous or leaky bottoms that interact with the Floridan aquifer. These lakes depend on roundwater levels to stay hih. If aquifer levels are low, these lakes o dry even if rainfall is normal. The District monitors 14 lakes with much of the data provided by volunteer observers. Most records o back to the 1970s, althouh the Sampson Lake record starts in 1957.

10 Fiure 9: Quarterly Sprinflow Measurements The SRWMD monitors water quality at 30 sprins. Flow is measured at the time of the samplin. The sprins below were measured in September 2013, with the last measurement marked in red. Flow is iven in million allons per day (MGD). Sprin flow is reatly affected by river levels. Risin river levels or hih tides can slow sprin flow or even reverse it, resultin in neative flow rates as river water enters the sprin. Some low flows in this data may not be representative of drouht conditions. 1 Lafayette Blue Sprins on Suwannee River Telford Sprins on Suwannee River Sprin Flow, Million Gallons per Day Ruth Sprins on Suwannee River White Sulphur Sprins on Suwannee River

14 Fiure 12a: Reional Lon Term Upper Floridan Monitor Wells (September 2013) The Floridan aquifer system underlies Florida and parts of Alabama, Georia, and South Carolina. It is one of the most productive aquifers in the world. In the SRWMD and surroundin areas,it is the primary source of irriation and domestic drinkin water, as well as the source of sprins that sustain river flow durin drouhts. Rechare to the Floridan occurs naturally as rainfall filters beneath the root zone of plants in uplands, wetlands, and some lakes and rivers. The rechare rate depends on the soils and deree of confinement of the underlyin eoloy. Unconfined areas frequently consist of porous sands and limerock that permit hih rechare from rainfall and surfacewater. Rechare to confined areas is restricted by nearly impermeable deposits, such as clay, that bound the top of the aquifer. Semi-confined areas are bounded at the top by thinner or breached impermeable deposits. Water levels in the Floridan chane in response to climatic conditions and pumpin. A number of aencies in addition to the SRWMD monitor water levels in the Floridan. Of hundreds of monitor wells across Florida and Georia only a few have continuous records that predate the 1980's. The wells on this map and a selection in fiure 12b are the wells in and near the SRWMD with the lonest continuous records.
