Surface Water Improvement and Management

Main SWIM photo reference

Overview

The Surface Water Improvement and Management (SWIM) Act was enacted in 1987 by the Florida Legislature to improve and manage the water quality and natural systems of Florida’s surface waters, which include lakes, rivers, streams, estuaries, springs, and wetlands.

The SWIM program is implemented by the Northwest Florida Water Management District, working cooperatively with the Florida Department of Environmental Protection(DEP), other state and federal agencies, local governments, and private stakeholders and initiatives to accomplish watershed protection and restoration objectives.

The District has approved a SWIM priority list that includes all seven of the major riverine-estuarine watersheds of northwest Florida, as depicted here:

Northwest Florida Watersheds Partnership Program

The Northwest Florida Watersheds Partnership Program will provide funding for planning, data collection, design, and implementation of projects to enhance water quality, aquatic habitat, and water supply in priority sub-basins within the Northwest Florida Water Management District. 

This new program builds upon prior work to develop Surface Water Improvement and Management (SWIM) plans for each of the District’s seven major watersheds. Under the Watersheds Partnership Program, one priority sub-basin will be selected within each of the seven major watersheds where focused planning, coordination, and funding will facilitate the implementation of projects to address critical water resource issues. Work plans developed for each priority sub-basin will include a description of the basin, water resource issues and causes, projects that can address and remedy critical issues, and associated funding needs. 

The Program will be implemented in coordination with local and county governments, regional entities, and other interested and affected parties to maximize effectiveness. These potential partners include the Florida Department of Environmental Protection, the Apalachicola National Estuarine Research Reserve, the Choctawhatchee Basin Alliance, and the three Panhandle Estuary Programs: the Pensacola and Perdido Bays Estuary Program, Choctawhatchee Bay Estuary Program, and the St. Andrew and St. Joseph Bays Estuary Program.   

During October 2025, the District hosted public workshops for each of the seven watersheds to share information about the program and obtain input regarding the prioritization of sub-basins for work plan development. In addition to the public meetings, the District is accepting input via online surveys. 

To provide input regarding the selection of priority sub-basins within each watershed including water resource areas of concern, please click on the survey links below. Public input will be accepted through October 27, 2025. Draft work plans for each of the seven priority sub-basins are anticipated to be completed in January 2026.

SWIM Plans

SWIM plans are developed to address, on a watershed basis, cumulative anthropogenic impacts to water quality and aquatic habitats. They incorporate comprehensive strategies to both restore and to protect watershed resources. Implementation is accomplished through a variety of activities, such as retrofitting stormwater management systems to improve water quality and flood protection; restoring wetland and aquatic habitats; supporting enhanced wastewater management and treatment; evaluating resource conditions and freshwater needs; protecting and restoring springs; and providing public outreach and awareness.

The SWIM program also supports coordination of state and federal grants and implementation of cooperative projects with local governments.

Historically, SWIM plan implementation has integrated and leveraged a variety of funding sources, including SWIM (sections 373.451-373.459, F.S.), the Water Management Lands Trust Fund (section 373.59, F.S.), the Ecosystem Management and Restoration Trust Fund (section 403.1651, F.S.), Florida Forever (section 259.105 and section 373.199, F.S.), legislative special appropriations, the Water Protection and Sustainability Program (section 403.890, F.S.), state and federal grants, and funding through local government partnerships. Cumulatively, the overall effort has resulted in significant protection and improvement of water resources District-wide.

SWIM priority waterbodies of the Northwest Florida Water Management District are listed below.  The waterbodies listed are inclusive of all tributaries, sub-embayments, and contributing watershed areas.

SWIM Priorities

The SWIM program’s primary focus is watershed management, encompassing water quality and natural system protection and restoration. Cooperative activities conducted under SWIM also provide improvements for flood protection, water supply, and public recreation. The SWIM priority list is updated annually in the Consolidated Annual Report. In addition to respective watersheds, the list identifies major tributaries and waterbodies. All other tributaries, sub-embayments, and contributing basins are also considered as being within the listed priority waterbodies.
