ACF STAKEHOLDERSa 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.

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

Page 6: SUSTAINABLE WATER MANAGEMENT PROJECT OVERVIEW Mitch Reid Brad Moore August 2013

2011 consensus on a science based approach

Developed specifications and executed RFQ Process

Initiated fundraising campaign Chose contractors and started fall 2011

WATER BALANCE

1. Water Withdrawals – Tabulation of existing and growth based (future) water users in the basin; includes municipal, industrial, agricultural, and thermoelectric users

2. Water Returns – Tabulation of existing and future returns from municipal and industrial NPDES permit holders

Withdrawals

Returns

Net Consumption = Net Consumption = SSWithdrawals - Withdrawals - SSReturnsReturns
