How are we going to adequately meet the increasing and
competitive needs for water by the natural, urban, and agricultural areas?
Part 2: Meeting the water needs of the future

Timing of the present system |
Seasonal Distribution of Flows Across Selected Transects ("the timing problem")
(Click on graphic below for larger version.)
The water management under 1995base (a
reference condition) and the projected 2050base show the following:
- In spite of the environmental benefits of
some flows to tide, they are large and part of it can be captured and stored,
- Seepage from the eastern boundary of the Everglades
system is large,
- Present operating rules include only minimal
discharges (only to ENP) for the environment, and
- Water management has altered the timing of
flows in the Everglades (figure above).

| The Restudy Plan
Features |
The Restudy Plan has the following primary
features for managing the system for environmental restoration while meeting
the needs of the urban and agricultural sectors:
- Extensive storage (both above ground and below
ground reservoirs as well as Aquifer Storage and Recovery) andStorm Water
Treatment Areas (STAs) for water quality treatment,when necessary,
- Operational modifications that (a) attempt
to mimic natural variation of water depths due to rainfall, (b) include
long-term climatic outlook, and (c) specify discharges to meet the environmental
needs of the Everglades and the estuaries,
- "Decompartmentalization" as much as possible
without causing over-drainage,
- Other infrastructure changes for better water
management in meeting the needs of all users,
- Seepage Management
- Wastewater Reuse in Miami-Dade County.

The performance of the Restudy Plan include,
but are not limited to the following:
- Capture and storage of nearly a million acre
feet of flows to tide for meeting the increasing needs of the environment,
urban and agricultural users while meeting the environmental needs of the
estuaries,
- Substantial reduction of water loss due to
seepage on the eastern boundary of the remnant Everglades,
- Significant increase in the water deliveries
to meet the environmental needs throughout the Everglades and the estuaries,
and
- Restoration of the timing of flows in the
Everglades (see figure above).
