Section 5 Formulation of Alternative Plans

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

5-6

This location would require that the runoff from the EAA be pumped north

through Lake Okeechobee and again pumped into storage reservoirs. This

would require extensive pumping facilities to physically transfer the water, as

well as treatment of the water before allowing it to enter the lake and again

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

standards. It should also be noted that expanding the size of the reservoirs will

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.

5.2.1.3 Storage East and West of Lake Okeechobee

The Comprehensive Plan includes water storage in the basins to the east and

west of the lake. For the C-43 basin west of the lake, the objectives are

capturing basin runoff and releases from the lake to provide water supply,

attenuation of regulatory releases, water supply deliveries to the Caloosahatchee

Estuary, and water quality benefits to reduce salinity and nutrient impacts of

runoff to the estuary. For the C-44 basin east of the lake, which is incorporated

into the Indian River Lagoon PIR, the objectives of the storage reservoirs are

capturing basin runoff to provide flood flow attenuation to the estuary, water

supply deliveries to the estuary, and water quality benefits to the St. Lucie

Estuary by reducing salinity and nutrient impacts of runoff to the estuary. The

C-43 Basin Storage Reservoirs project implementation report is currently

underway and includes formulation and evaluation of Restudy Compartment D

(C-43 Basin Storage Reservoir) estimated in the Comprehensive Plan to total

approximately 160,000 acre-feet of storage. The Indian River Lagoon PIR has

been completed and approved by the Chief of Engineers, and includes the C-44

reservoir, totaling approximately 33,150 acre-feet of storage and 6,000 acres of

STAs. (The Indian River Lagoon [IRL] project includes other project features

outside of the C-44 basin.)

These reservoirs could conceivably be expanded to include the additional storage

that the EAA Storage Reservoirs project is intended to hold. Additional water

stored in above-ground reservoirs to the west and east of the lake could meet the

following planning objectives:

1. Improve the timing of environmental deliveries of water to the WCAs.

More water could be moved from east or west of the lake to the lake and

then southward through the EAA to the WCAs to meet the needs of the

natural system.

2. Reduce Lake Okeechobee regulatory releases of water to the WCAs. The

storage east or west of the lake could receive water from or hold water

back from entering the lake. This would reduce the need to release lake
