Section 5 Formulation of Alternative Plans

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

water southward to the WCAs to meet regulation schedules when the

WCAs already have too much water.

3. Reduce regulatory releases of water from Lake Okeechobee to the St.

Lucie and Caloosahatchee Estuaries. Storage in both the C-44 and C-43

basins to the east and west of the lake can hold water back and not send it

to the lake or the estuaries. This would reduce the need to release lake

water to meet regulation schedules to the east and west estuaries in such

large volumes that their natural salinity regimes are harmed.

4. Meet agricultural demands within the EAA. More water could be moved

from east and west of the lake to the lake and then southward to the EAA

to meet the needs of agriculture.

5. Increase flood protection within the EAA. Flood runoff could be

backpumped from the EAA through the lake to storage east and west of

the lake to reduce flood damages.

To capture excess agricultural runoff from the EAA, like the north of Lake

Okeechobee location, the water would be pumped north through Lake

Okeechobee and again pumped east or west into storage reservoirs. This would

require new, massive pumping systems and treatment systems for the water.

Treatment is required before water is allowed to enter Lake Okeechobee and

again prior to discharging back to the lake to meet current state water quality

standards.

Water stored in expanded reservoirs east and west of Lake Okeechobee must

ultimately be released either back to the lake to increase the quantity of water

delivered to the Everglades or to one or both estuaries. While peak regulatory

releases to the estuaries may be further moderated with additional storage east

and west of Lake Okeechobee, it seems likely that this concept could result in

more freshwater sent to the estuaries than is being planned for in the C-43

Basin Storage Reservoir and IRL-South projects and less efficient delivery of

additional water to the WCAs. Thus, this location most likely would not achieve

the entire ecosystem benefits in the Caloosahatchee and Indian River Estuaries

that would be achieved by locating the EAA Storage Reservoirs project

elsewhere.

Expanding the size of the reservoirs for this option will also take additional

property off the tax roles in largely rural counties. This would be expected to

have negative impacts on the socioeconomic components of the environment in

these counties.
