For the 2020 report, the committee reviewed the recently developed Combined Operational Plan and examined issues facing the northern and south ern estuaries, including priorities for science to support restoration decision making. With several projects nearing completion, the 2020 report noted that the CERP is now pivoting from a focus primarily on project planning and construc tion toward an expanding emphasis on operational decisions, evaluation of restoration success, adaptive management, and learning.

In the 2018 report, the committee noted that a vision for planned CERP storage, at least in the northern portion of the system, was now becoming clear, although the future storage to be provided by Lake Okeechobee remains unresolved. The committee concluded that documentation and analysis of incre mental restoration benefits from project implementation to date have been inadequate, primarily because of limitations in project-level monitoring and assessment efforts.

conducted an 11-year ASR Regional Study, with focus on the hydrogeology of the Floridan aquifer system, water quality changes during aquifer storage, possible ecological risks posed by recovered water, and the regional capacity for ASR implementation. At the request of the USACE, this report reviews the ASR Regional Study Technical Data Report and assesses progress in reducing uncertainties related to full-scale CERP ASR implementation.

To reverse ongoing ecosystem declines, it will be necessary to expedite restoration projects that target the central Everglades, and to improve both the quality and quantity of the water in the ecosystem. The Central Everglades Planning Project offers an innovative approach to this challenge, although additional analyses are needed at the interface of water quality and water quantity to maximize restoration benefits within existing legal constraints.

However, some important projects have been delayed due to several factors, including budgetary restrictions and a project planning process that can be stalled by unresolved scientific uncertainties. The report outlines an alternative approach that can help the initiative move forward even as it resolves remaining scientific uncertainties.

Given the uncertainties that will attend future responses of Everglades ecosystems to restored water regimes, a research, monitoring, and adaptive management program is planned. This report assessed the extent to which the restoration effort's "monitoring and assessment plan" included the following elements crucial to any adaptive management scheme: (1)

Monitoring, modeling, and research should be well integrated, especially with respect to defining the restoration reference state and using "active" adaptive management. Does Water Flow Influence Everglades Landscape Patterns?

Complicating the analysis of such issues is the lack of an operational bay circulation model. The report notes the importance of additional research in the following areas: estimates of groundwater discharge to the bay; full characterization and quantification of surface runoff in major basins; transport and total loads of nitro gen and phosphorus from freshwater sources, especially in their organic forms; effects on nutrient fluxes of decreasing freshwater flows into the northeastern bay, and of increasing flows northwest of the bay; and the development of an operational Florida Bay circulation model to support a bay water quality model and facilitate analysis of CERP effects on the bay.

Regional Issues in Aquifer Storage and Recovery for Everglades R estoration: A Review of the ASR Regional Study Project Management Plan of the Comprehensive Everglades Restoration Plan (2002) The report reviews a comprehensive research plan on Everglades restoration drafted by federal and Florida officials that assesses a central feature of the restoration: a proposal to drill more than 300 wells funneling up to 1.7 billion gallons of water a day into underground aquifers, where it would be stored and then pumped back to the surface to replenish the Everglades during dry periods.

It also recommends that water quality studies include laboratory and field bioassays and ecotoxicological studies, studies to characterize organic carbon of the source water and anticipate its effects on subsurface biogeochemical processes, and laboratory studies. Finally, it recom mends that pilot projects be part of adaptive assessment.
