SOUTH FLORIDA WATER MANAGEMENT DISTRICT

Summary of Model Jose Otero, P.E. Section Leader Scenarios Hydrologic & Environmental Systems Modeling WRAC Issues Workshop June 27, 2013 SOUTH FLORIDA WATER MANAGEMENT DISTRICT

Objective

• To assess the potential differences in the hydrologic response of the South Florida system as a result of differences in water demand and land use in the Lower East Coast planning area between 2010 and 2030 SOUTH FLORIDA WATER MANAGEMENT DISTRICT

Key Modeling Assumptions

• System Operations as of 2012, such as: – C&SF operating rules and schedules – LORS 2008 for with estimated Adaptive Protocols – LOWSM per rule 40E-21 and 40E-22 – ERTP for WCA 3A • Current ECP, C-111 South Dade, and ACME Basin B • No future restoration projects SOUTH FLORIDA WATER MANAGEMENT DISTRICT

Definition of Terms for Hydrologic Change

• No change or minimal change. Detectable but not significant. • Slight change: 1% of volume or 0.1 ft of stage. Not significant in most cases. • Small change: 2% of volume or 0.2 ft of stage. Significant in some cases. • Moderate change: 5% of volume or 0.5 ft of stage. Significant in many cases. • Considerable change: Significant in most cases. SOUTH FLORIDA WATER MANAGEMENT DISTRICT

Summary of Assumptions

• 2030 demands within existing CUPs

• No restoration or mitigation projects

• 2030 land use changes consistent with Comprehensive Plans or permits

• Did not allow flexibility to shift from SAS to FAS during water shortages

SOUTH FLORIDA WATER MANAGEMENT DISTRICT

Summary of Results

• Natural Systems – Minimal changes for Lake Okeechobee and the Everglades – Improved performance of natural systems will require restoration projects – Reduction of WCA-3B stages should be prevented by required mitigation – Small decrease in stormwater to tide • Lake Okeechobee Service Area – Isolated land use changes slightly increases storage and demands met • Lower East Coast Service Area – Small increase in regional water supply – Increased water shortages in two service areas should be offset by existing FAS and RO facilities at Jupiter and Hollywood
