Section 5 Formulation of Alternative Plans

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

C-43 Reservoir, to capture basin runoff without the added burden of Lake

Okeechobee water.

FIGURE 5-9: ECOLOGICAL BENEFITS FOR CALOOSAHATCHEE ESTUARY.

5.4.2.2.4 Greater Everglades

The model output shows an overall slight benefit to the ridge and slough habitat

within WCAs 2 and 3 between the future without project and the 360,000 acre-

foot reservoir, with quality index scores of 0.75 and 0.88, respectively. A larger

benefit is seen for the tree islands, with scores of 0.67 and 0.86 between future

without project and the project, respectively. While the improvement to the

habitat may be slight, the effects are far-reaching, covering at least 257,586

acres of ridge and slough habitat, with 11,788 acres of that consisting of the tree

islands. Annualized benefits are shown for these habitats in Figures 5-10 and

5-11. As in the other geographic regions, Alternatives 2 and 3 have delayed

benefits due to the time required for buying additional land. This particular

model output shows the future-without-project benefits increasing in the future.

This relationship is thought to be the influence of rain-driven operations, which

is actually part of full CERP implementation. A revised model run will be

conducted with the corrected future assumptions, and revised ecological benefit

calculations will be completed for the final PIR. Ridge and slough and tree

island outputs were not calculated for Everglades National Park, even though it

is expected that project implementation will increase the quantity and improve

the timing of water delivered to the Park consistent with restoration objectives
