The Everglades restoration program has completed the arduous federal project planning and authorization processes for three projects and and is now moving forward with construction of the Picayune Strand project with federal funding. Additionally, despite budget challenges, the state of Florida continues to expedite the construction of three projects (C-111 Spreader Canal, Biscayne Bay Coastal Wetlands, and Lakeside Ranch Stormwater Treatment Area)

Although the benefits of the 1-mile bridge represent only a fraction of those envisioned in earlier Mod Waters plans, planning is under way to consider additional bridging that could take advantage of a downturn in construction costs. The River of Grass initiative could create options for additional water storage and water quality treatment to help meet CERP objectives.

. These projects offer significant restoration benefits to the remnant Everglades ecosystem, but the benefits cannot be fully realized without the provision of additional water, which will require substantial new storage and associated water quality treatment.

Little recent progress has been made in developing integrated hydrologic, ecological, and biogeochemical models to inform restoration decision making and to provide input for adaptive management. Hydrologic modeling has been the primary focus of CERP model development efforts, and substantial progress has been made on the Natural System Regional Simulation Model (NSRSM)

Over the next 5-10 years, CERP and pre-CERP projects will improve the conveyance and distribution of water in southern WCA-3A and Everglades National Park. But until additional water of sufficient quality becomes available, the restoration benefits will be modest and could result in shorter hydroperiods and more severe dry-down events in northern WCA-2A and

WCA-3 is a growing focus of public controversy and management concern because of its location and the way the entire system is operated to manage water distribution and quality. WCA-3A supports extensive and relatively intact Everglades landscapes including ridge and slough patterns and tree islands, and it provides critical habitat for endangered species, such as the snail kite and wood stork.

, and addressing recent violations of the Consent Decree. In addition to considering additional treatment and source control, this analysis should evaluate urban and agricultural water supply management approaches and accelerated sequencing for seepage management projects to determine whether changes could address water quality and water quantity concerns in a more efficient manner.

A rigorous research, monitoring, and modeling program focused on developing improved best management practices is needed to improve the efficiency of phosphorus source control efforts and to inform systemwide phosphorus management decisions. Long-term monitoring of the efficacy and costs of best management practice implementation across multiple sites will be required to evaluate source control practices across variable hydrologic, geomorphologic, and soil regimes present in the South Florida ecosystem and to validate and build confidence in predictive models.

Likewise the transport and removal of phosphorus may be coupled with the supply of calcium in Lake Okeechobee, the STAs, and other portions of the Everglades. Additional research is also needed to clarify the linkages between water quality constituents to support sound multi contaminant water management decisions.
