Mobile Tensaw Delta

The Mobile-Tensaw Delta Watershed is the downstream endpoint of the Mobile Bay watershed which drains three-quarters of the state of Alabama and parts of Georgia, Mississippi, and Tennessee. The Mobile Bay watershed is the fourth largest watershed in the U.S. in terms of volume of flow, which accounts for one-fifth of the freshwater supply in the country, and the sixth-largest based on drainage area.

The purpose of the Mobile-Tensaw-Apalachee (MTA) Watershed Management Plan (WMP) is to guide watershed resource managers, policymakers, community organizations, landowners, industry leaders, and citizens to protect the shoreline, water quality and habitat supporting healthy populations of people, wildlife, fish, and shellfish, and providing recreation and economic opportunities in coastal Alabama.

Goals and Objectives

  1. Improving water quality and habitats necessary to support healthy populations of fish and shellfish,
  2. Protecting continued customary uses of biological resources to preserve culture, heritage, and ecology of the watershed,
  3. Mitigating impacts from industrial uses on the watershed, while embracing the economic benefit of resident industries,
  4. Reducing and mitigating impacts of coastal erosion on the shoreline, and conserving, managing, and restoring critical coastal habitat,
  5. Education and coordination with landowners and industry leaders to develop sensible and effective best management practices,
  6. Improving watershed resiliency to sea-level rise and changing climate impacts, and
  7. Expanding opportunities for community access to the natural resources and waters of Mobile Bay.
