Bay Biodiversity
Habitat Types
Choctawhatchee Bay is a thriving ecosystem shaped by a variety of habitats that work together to sustain its rich biodiversity. Spanning approximately 437 square miles, the bay's coastal wetlands play a vital role as natural barriers, stabilizing the shoreline and filtering pollutants before they reach the open water.
Seagrass beds, covering about 4.7 square miles of the bay floor, act as essential nurseries for young fish and invertebrates. These underwater meadows are critical for both juvenile and adult marine species, offering food and shelter.
Oyster reefs in the bay not only support shellfish populations but also play a key role in reducing erosion. Often used in restoration projects, these reefs double as habitats for a variety of other species. The bay is also home to 10 rare coastal dune lakes, a feature unique to Florida and found in very few places globally.
Adding to this diversity, a network of riparian zones and streams brings freshwater into the bay. These areas create habitats for specialized species like the endangered Okaloosa darter, which is restricted to six small streams flowing into the bay.
Wildlife Species
The Choctawhatchee River Basin is a haven for wildlife, supporting at least 118 fish species, 41 mammal species, and 30 amphibian species. The bay itself serves as a federally protected foraging area for the Gulf Sturgeon, a threatened species that depends on free-flowing rivers for its migration and spawning.
Visitors to the bay often spot redfish, speckled trout, and largemouth bass in the shallows, while dolphins can be seen navigating the deeper waters. Along the coastal dunes, the endangered Choctawhatchee beach mouse finds its home, and the bay's marshes provide essential breeding grounds for protected bird species like the Least Tern.
Alison McDowell, Director of the Choctawhatchee Basin Alliance, highlights the importance of the bay's ecosystem:
"75-85% of commercially and recreationally important species that are caught in the Gulf spend part of their lifecycle in the Bay".
This includes species like blue crab and shrimp, which depend on the bay's brackish waters during key developmental stages. The Nature Conservancy emphasizes the bay's significance, stating:
"The Choctawhatchee represents two of these 87 watersheds that stand out as hot spots, harboring 10 or more imperiled species".
The bay's remarkable biodiversity not only preserves its ecological integrity but also enhances its value as a destination for recreation and exploration.

However, boaters should be aware that parts of the western bay are off-limits due to Eglin Air Force Base operations.
Conservation Programs
SWIM Plan
The Surface Water Improvement and Management (SWIM) Plan tackles the issue of urban stormwater runoff, which carries harmful substances like fertilizers, pesticides, and heavy metals into the bay. This runoff degrades both water and sediment quality, posing a serious threat to the ecosystem’s health. To combat this, the plan emphasizes monthly water quality monitoring, focusing on key indicators such as temperature, salinity, pH, dissolved oxygen, and nutrient levels. This data helps pinpoint problem areas and track progress over time.
One of the plan’s standout strategies involves the use of living shorelines. These include reef breakwaters made from recycled oyster shells and planting native smooth cordgrass. Together, these measures stabilize coastlines, create habitats for fish and wildlife, and act as natural filters to reduce pollutants. These efforts are crucial for maintaining the bay’s fragile ecosystem over the long term.
Choctawhatchee Bay Estuary Program
The Choctawhatchee Bay Estuary Program (CBEP) brings together government agencies, nonprofits, and local communities, following the framework of the EPA's National Estuary Program. At its core is the Comprehensive Conservation and Management Plan (CCMP) - a detailed guide for protecting the bay's vast 3,339,632-acre watershed, which spans parts of Alabama and Florida. The program is focused on addressing threats like rapid development and climate change while working to restore vital habitats and improve water quality.
"The purpose of this CCMP is to identify key resources, impacts, and strategies to protect the watershed for generations to come." - CCMP Executive Summary
Community involvement is a cornerstone of CBEP’s efforts. For example, the "Grasses in Classes" initiative educates 3rd and 5th-grade students in Okaloosa and Walton Counties about marsh ecosystems. Students grow smooth cordgrass and take part in hands-on shoreline restoration projects. In September 2024, CBEP hosted "Family Bay Day" at Fred Gannon Rocky Bayou State Park. This event featured educational activities designed to help families appreciate the ecological importance of the basin. Residents can also get involved by joining volunteer monitoring teams or participating in oyster shell recycling programs, which contribute directly to living shoreline restoration projects.

Hydrology and Watershed
Choctawhatchee River and Freshwater Inflows
Stretching 141 miles from central Alabama to the bay, the Choctawhatchee River plays a vital role in maintaining the bay's ecosystem. With an average freshwater inflow of approximately 240.69 m³/s (or 8,511 ft³/s), it creates the brackish conditions that support a wide range of species. Near East Pass in Destin, the water's salinity averages 25, an ideal environment for Gulf sturgeon and oysters.
The river's limestone bottoms serve as critical spawning grounds for Gulf sturgeon. In late 2008, researchers recorded 522 sturgeon in the area, weighing anywhere from 1 to 160 pounds. The river system is also fed by several major tributaries: Alabama’s Pea River and Little Choctawhatchee River, along with Florida’s Holmes, Wright, Sandy, and Pine Log creeks. These waterways not only support the ecosystem but also provide habitats for rare species like the endangered Okaloosa darter.
This intricate network of freshwater inputs is essential to the watershed, influencing water quality and fostering habitat diversity across the region.
Watershed
Covering a massive 3,339,632 acres (about 5,350 square miles), the Choctawhatchee watershed spans 60% in Alabama and 40% in Florida. It connects a variety of landscapes, including forested wetlands, marshes, and coastal barriers, all of which help filter water before it reaches the bay. The area also features 10 coastal dune lakes, further highlighting its ecological significance.
The health of the bay’s water is directly tied to conditions upstream. In Alabama, the river’s water quality generally ranges from good to very good. However, the Florida section faces challenges from pollution caused by wastewater and erosion. Urban stormwater runoff compounds the problem, carrying fertilizers, pesticides, and heavy metals from parking lots, lawns, and developed areas. This runoff impacts roughly 437 square miles of coastal wetlands and nearly 5 square miles of submerged aquatic vegetation.
