Section 5 Formulation of Alternative Plans

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

5-37

Ecological Models developed for each region by the RECOVER team as well as

information contained within the performance measure documentation sheets.

Each one the performance measures addressed one of the specific project

objectives. For example, one of the performance measures entitled, “Lake

Okeechobee Extreme High Stage” addressed the stated project objective of

“Habitat Improvement of Lake Okeechobee.”
