  1. SUSTAINABLE WATER MANAGEMENT Project Overview Mitch Reid Brad MooreAugust 2013

  2. ACF STAKEHOLDERS • a diverse group representing sectors in all three states – working together for the first time to achieve a common goal • achieve equitable water-sharing solutions among stakeholders that balance economic, ecological and social values, while ensuring sustainability for current and future generations. • After developing a strong organizational infrastructure and completing a forward-thinking strategic planning process, ACFS is now ready to move forward with the critical next steps, centered around developing a Sustainable Water Management Plan for the Basin. • Through scientific modeling and a shared vision process, ACFS will work to achieve a sustainable solution that works for everyone in the ACF Basin.

  3. ACF Basin

  4. WHAT IS THE SWMP? • Sustainable Water Management Plan • Use of hydrologic modeling of the ACF basin to allow informed decision making • Includes an evaluation of Apalachicola Bay

  5. PROJECT HISTORY 2011 consensus on a science based approach Developed specifications and executed RFQ Process Initiated fundraising campaign Chose contractors and started fall 2011

  6. Project Team TOCWG RESOLVE Gail Bingham

  7. FUNDING • Internal contributions • Grants

  8. In-stream Flow Analysis Task 3: Model Development Task 4: Model Inputs – Unimpaired Flows Dataset and Water Balance Task 6: SWMP Model Runs Sub-Task 6.1: Baseline/Current Conditions Model Runs Task 2: Performance Metrics: Evaluate Model Results Tasks 7 & 8: Develop consensus on SWMP Sub-Task 6.2: Model Runs to Evaluate WMA’s Task 1: Work Plan Task 5: Water Management Alternatives

  9. Modeling Modeling performed by GWRI Scenarios are be performed using both ResSim and ACF-DSS.

  10. PERFORMANCE METRICS • Desired lake levels • Navigation windows • Environmental flows • Flows needed for industry or thermal power

  11. PERFORMANCE METRICS EXAMPLES

  12. ENVIRONMENTAL METRICS • Performed Instream Flow Analysis • Utilized USFWS information • Utilized river keeper’s judgment

  13. HABITAT-BASED APPROACH

  14. Unimpaired flows Unimpaired inflow (UIF) series represent the natural inflows that would occur if no human development were present Using latest USACE UIF

  15. WATER BALANCE • Water Withdrawals – Tabulation of existing and growth based (future) water users in the basin; includes municipal, industrial, agricultural, and thermoelectric users • Water Returns – Tabulation of existing and future returns from municipal and industrial NPDES permit holders Withdrawals Returns Net Consumption = SWithdrawals - SReturns

  16. Water Management Alternatives PROCESS Utilized a panel of experts to review to receive briefing. Stakeholder meetings to develop WMAs Screening process of WMAs during iterative model runs.

  17. WMA Examples Potential changes to RIOP Interbasin transfers Municipal conservation Additional storage Agricultural conservation/limits

  18. Modeling scenario progression Baseline runs Alternative WMA Scenarios (iterative)

  19. BASELINE RUNS • No reservoirs, no controls, no consumption • Reservoirs with run of river, no consumption • Reservoirs with UASCE controls, no consumption • Current conditions including net consumption

  20. FIRST ITERATION RUNS • Change consumption in range of +/- 30% • Drop all IBT’s • Raise Lanier by 2 ft

  21. SECOND ITERATION RUNS • To focus on insights from round one and changes to RIOP

  22. APALACHICOLA BAY IMPACT • Running hydrodynamic bay model to evaluate saline changes • Performing an ecological evaluation of impact to oysters based on salinity changes

  23. Where are we now? OVERALL SUSTAINABLE WATER MANAGEMENT PLAN TASKS 1. Work Plan 2. Problem Definition/Performance Indicators 3. Tailoring of Models to Indicators (ACF-DSS and ResSim) 4. Data and Information 5. Development of Water Management Alternatives 6. Conduct Iterative Basin Assessments 7. Seek Consensus 8. Report and Study Dissemination NOV DEC JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC JAN FEB

  24. Report dissemination ACFS will carry recommendations to states and usace
