Source classes are generally divided into surface water use basins and groundwater sources. A water user may be assigned any combination of both surface water use basin and groundwater source classes.

(1) Surface Water Use Basins. Surface waters are classified by surface water use basin. Descriptions of the boundaries of the surface water use basins are found in Rule 40E-21.691, F.A.C. The surface water use basins are grouped by region as follows (see Figure 21-1):

(a) Water Conservation Area/Everglades National Park (see Figure 21-2).
1. The surface water use basins in this area are directly supplied with surface water from the Water Conservation Areas and Everglades National Park. The following surface water use basins are included in the area:

2. Water Conservation Areas/Everglades National Park Water Use Basin.

(b) Lower East Coast (see Figure 21-3) The water use basins in this area are directly supplied with surface water from the Water Conservation Areas or the M Canal. The following surface water use basins are included in the area:
1. Interior Palm Beach County Water Use Basin.

2. Loxahatchee River Water Use Basin.

3. C-18 Water Use Basin.

4. North Palm Beach County Water Use Basin.

5. M Canal Water Use Basin.

6. Water Conservation Area 1 West Palm Beach Canal Water Use Basin.

7. Water Conservation Area 2 Water Use Basin.

8. Water Conservation Area 3 Water Use Basin.

9. South Dade Water Use Basin.

(c) Lake Okeechobee (see Figure 21-4) The surface water use basins in this area are directly supplied with surface water from Lake Okeechobee. The following surface water use basins are included in the area:
1. Everglades Agricultural Area Water Use Basin.

2. Caloosahatchee River Water Use Basin.

3. St. Lucie River Water Use Basin.

4. Lakeshore Perimeter Water Use Basin.

(d) Upper East Coast (see Figure 21-5) The surface water use basins in this area are directly supplied from local surface waters. The following surface water use basins are included in the area:
1. St. Lucie County Agricultural Area Water Use Basin.

2. Coastal St. Lucie County Water Use Basin.

3. Port St. Lucie Water Use Basin.

4. Northwest Martin County Water Use Basin.

5. South Coastal Martin County Water Use Basin.

6. North Coastal Martin County Water Use Basin.

7. West Coastal Martin County Water Use Basin.

8. Stuart Peninsula Water Use Basin.

9. Interior Martin County Water Use Basin.

10. Northwest Loxahatchee River Water Use Basin.

(e) Kissimmee (see Figure 21-6) The surface water use basins in this area are directly supplied with surface water from the West Chain of Lakes, the Upper Chain of Lakes and the Kissimmee River. The following surface water use basins are included in the area:
1. West Chain of Lakes Water Use Basin.

2. Upper Chain of Lakes Water Use Basin.

3. Kissimmee River Valley Water Use Basin.

4. Taylor Creek-Nubbin Slough Water Use Basin.

(f) Indian Prairie (see Figure 21-7) The surface water use basins in this area are directly supplied with surface water from Lake Istokpoga and Fisheating Creek or associated surface water bodies. The following surface water use basins are included in the area:
1. Indian Prairie Water Use Basin.

2. Fisheating Creek Water Use Basin.

(g) Lower West Coast (see Figure 21-8) The surface water use basins in this area are directly supplied from local surface waters. The following surface water use basins are included in the area:
1. Caloosahatchee River Watershed - North, Water Use Basin.

2. Caloosahatchee River Watershed - South, Water Use Basin.

3. South Hendry County/L-28 Gap Water Use Basin.

4. Big Cypress Preserve Water Use Basin.

5. Fakahatchee North Water Use Basin.

6. Fakahatchee South Water Use Basin.

7. Coastal Collier County Water Use Basin.

(2) Groundwater Sources. Groundwater sources are classified based upon the available hydrologic information, and the restricted area may include aquifers underlying all or part of a county, municipality, surface water basin or utility service area, as follows:

(a) Water table aquifers. Groundwaters directly recharged by surface waters and rainfall are classified according to the surface water use basin within which they are located. The titles and boundaries described in subsection (1) shall apply.

(b) Confined and semiconfined aquifers. Groundwaters not directly recharged by surface waters and rainfall are classified as follows:
1. Potable Floridan Aquifer.

2. Non-Potable Floridan Aquifer.

3. Sandstone Aquifer.

4. Upper Hawthorn Aquifer.

5. Suwannee Aquifer.

6. Lower Hawthorn Aquifer.

7. Other artesian or leaky artesian aquifers.

(c) Figures 21-2 through 21-8 list the water table, confined and semiconfined aquifers generally found within each surface water use basin. Adjacent areas which are supplied from a restricted groundwater source may also be included in the restricted area.
