Section 5 Formulation of Alternative Plans

EAA Storage Reservoirs Revised Draft PIR and EIS February 2006

5-40

It is anticipated/planned that projects such as the Modified Water Deliveries to

Everglades National Park Project will have reduced and/or eliminated many

existing operational and structural constraints by the time the EAA Reservoir

Project becomes operational. Consistent with the general operational intent of

the EAA Reservoir, it is intended that the reservoir will be operated in a manner

consistent with restoring and/or sustaining hydrologic conditions necessary to

protect fish and wildlife. Toward that end, it is intended that the reservoir will

be operated in the absence of existing constraints:

• to receive water from Lake Okeechobee and/or from surrounding

agricultural runoff;

• to deliver water from the reservoir to downstream natural areas via STA-

3/4 during the wet and dry seasons in a manner consistent with stage

and/or volume-based restoration targets; and

• to deliver water from the reservoir to meet local agricultural water supply

demands that would otherwise be met via deliveries from the regional

water management system.

Once existing constraints on operations are reduced and/or eliminated such that

additional water could be delivered in a manner consistent with restoration

goals, total volumes of water made available by the EAA Reservoir project for

introduction to the Everglades Protection Area are anticipated to be greater than

existing levels. Such deliveries will be released to the Everglades Protection

Area by way of STA-3/4. Because the volumes of water to be delivered to the

Everglades Protection Area are likely to increase in the future and/or as more

CERP projects are constructed, it is possible that additional STA optimization

and/or capacity might be required to handle the additional hydraulic and

nutrient loading rates associated with CERP-like deliveries. The potential need

for additional STA optimization and/or capacity is being investigated.

5.4.2.1.5 Quantifying Performance Measures

Where possible, performance measure targets and scores were converted into a

standardized scale of ecosystem conditions on a 0.1-1 scale and used in

aggregation equations. The framework for ecosystem condition benchmarks

could be presented as indicated below (Table 5-15):

The Indian River Lagoon South Project used such a system to convert certain

performance measure values from a raw score or percent target achieved to

ecosystem condition, or “quality values.” The quality values were defined based

on known ecological principles for the potential effects of the project performance

measures. The “quality” factor applied in subsequent calculations was a

measure of the quality of the resource, as applied to a specific restoration

objective.
