Hunting
is one of over 500 national wildlife refuges. The primary objective of a national wildlife refuge is to provide habitat for the conservation and protection of all wildlife species.
Carefully managed hunts are one tool used to manage wildlife
populations.

Small- and large-game hunting with bows and provides high-quality recreation for many people. Wheeler NWR offers public hunting on approximately 18,000 acres, and hunting regulations are published each year
in the WNWR hunting permit brochure. Hunters are allowed to hunt , , , , , , and .
is not permitted on the refuge.

500+ acres between HGH Road and the Tennessee River are designated as a special access hunting area for .
Special access permits are available at .

Fishing is a very popular activity at Wheeler NWR, with an estimated 274,000 anglers trying their luck each year in the 18,000 acres of refuge waters.
Many creeks and sloughs adjoin the main channel of the Tennessee River throughout the refuge. Old river channels, open blackwater embayments, and
miles of tree-lined creeks and streams provide excellent fishing opportunities for , smallmouth, spotted, , and , bluegill and redear sunfish, crappie, sauger, several species of catfish, and a few yellow perch.

A universally accessible is available on Flint Creek across Highway 67 from the Visitor Center.

A three-acre is available for organized events.
Each year, groups ranging from special needs children and adults to summer
day campers and enjoy fishing at the pond. U. S. Fish and Wildlife Service
Water Level Management
Wheeler NWR staff manages impoundment water levels on the refuge to provide habitat for wintering waterfowl. are enclosed bodies of water, such as a . The management of these areas creates moist soil and flooded cropland conditions that produce natural, desirable vegetation and high-calorie food for waterfowl. Impoundments provide lasting benefits to colonial waterbirds, marsh birds, and shorebirds.

To grow moist soil plants, water levels in the must be lowered in the spring for the germination of wetland plants. The areas are then flooded in the fall just before waterfowl begin to arrive. A lack of water management limits the food and plant options available to the birds. This management objective is difficult to accomplish when TVA raises and lowers Wheeler Reservoir according to a schedule that is the opposite of what is needed to sustain waterfowl.

Farming
3.500 - 4,000 acres are cooperatively farmed on the refuge. Cooperative farming is a mutually beneficial arrangement in which farmers are allowed to farm refuge land under specific guidelines and restrictions, including leaving a share of the crop (18-20%) for waterfowl and wildlife. It provides food, browse, cover, and nesting areas for waterfowl and other wildlife species.

Crops grown include soybeans, corn, winter wheat, milo, and millet. Various waterfowl, such as Canada geese, , Sandhill Cranes, and Mallards, feed in the fields during fall and winter. Deer enjoy feeding on corn, soybeans, and winter wheat, while raccoons and squirrels drag ears of corn into the woods and feed on it there. Various species of songbirds also feed on these crops.

Our History
1838
: The discovery of gold in Georgia and thirst for land expansion prompted the U.S. Government and white communities to force the from their ancestral lands. During the summer and winter of 1838, the first three detachments driven west traveled by water on the from near present-day . They followed the river through and West Tennessee before merging with other rivers and eventually arriving in .

1933
: In May of 1933, President signed the Act, creating the TVA. The Tennessee Valley Authority was designed to modernize the region, using experts and electricity to combat problems in the area. A primary part of the plan was to produce electricity and provide flood relief by constructing a series of dams along the Tennessee River and its tributaries.

1934
TVA COMES TO Town TVA acquired land in the middle third of the valley in 1934-35 to serve as a bed for and buffer around . Interested individuals and organizations urged that the government take advantage of the newly constructed reservoir to replace the waterfowl habitat.

1938
AN EXPERIMENT: On July 7, 1938, President Franklin Roosevelt set aside the middle third of the new reservoir as an experimental national wildlife refuge to see if multi-purpose reservoirs could be made attractive to waterfowl. The reservoir and new refuge were named for , who lived near .

1950
POLLUTION: 's 1962 classic, , documented the serious environmental problems caused by , including those in the . In the late summer of 1950, farmers experiencing a very wet season reapplied pesticides to their crops multiple times because they kept washing off in the frequent rains. These high volumes of pesticides washed into Flint Creek, killing most of the fish.

Present
HERE AND NOW, significantly impacted by its controversial history, this section of the Tennessee River and Flint Creek is vastly different from what they were over 170 years ago when the Cherokee traveled west. Industries have sprung up, dams have been built, commercial water traffic is considerable, and recreational boating facilities have developed. Wheeler National Wildlife Refuge is one of the few remaining areas along the river dedicated to conserving the character of our wild and natural heritage.

Flint Creek
Flint Creek is a slow-flowing, meandering stream influenced by the fluctuating water levels of Wheeler Reservoir. The creek and its tributaries comprise 150 miles of streams that drain over 291,000 acres of land in , , and . Its headwaters are in northern Cullman County, and the creek flows into Morgan County, where it converges with near . As it confluences with the Tennessee River at mile 308.5

Fishing and Land
The Flint Creek shoreline offers a wide variety of hardwoods, bluffs, farms, and wildlife, while the stream itself is home to , , , , and a few . Much of the land surrounding the creek is within the TVA Reservation and Wheeler National Wildlife Refuge, making it accessible to the public. Improved boat launching areas are available at and . An improved launch area suitable for small boats and canoes is located south of . This universally accessible pier was built so everyone can enjoy what the watershed has to offer.

The Flint Creek Watershed Project is a multiagency cooperative led by local leaders and watershed residents. In 1996, a was established, and plans were developed with assistance from two federal agencies, five Alabama state agencies, and three local . This project has implemented a variety of projects, including agricultural demonstrations, well sampling programs, on-site wastewater demonstrations, and riparian zone management efforts. Public outreach activities include household hazardous waste days and .

Seagrass, Soup of the Sea and Migratory Birds

Soup of the Sea

are organisms that drift with currents. Plankton can be plant-like or animal-like . Most plankton are small, but even larger organisms are considered plankton if they live their lives drifting with currents. Plankton is found in freshwater and saltwater worldwide and is essential to humans.

Thank your plankton

Imagine your favorite seafood - shrimp, crab, oysters, fish ... thanks to phytoplankton, we can enjoy this mouthwatering cuisine from the sea. Phytoplankton provides two essential things for animals (including us) to live. One is food. Like plants on land, they use sunlight and nutrients to produce food. They're the base of the food chain in the ocean. Many tiny animals eat phytoplankton and, in turn, get eaten by larger animals up the food chain. Without plankton, we would not have seafood.

Now, take a deep breath. The second essential ingredient produced by phytoplankton is oxygen. Estimates vary, but most scientists agree that phytoplankton make up a significant portion of Earth's atmosphere.

There's a zoo out there.

Zooplankton eat. Many eat phytoplankton, and many eat smaller zooplankton. They are an essential part of the food chain. A shark may never eat plankton and has no idea it exists, but it depends on plankton for all of its food.

Many zooplankters go through a . Some of them are plankton for part of their lives and then grow large enough to swim against currents or settle to the bottom. Those are called . are plankton their whole lives.

You might recognize the adult forms of many meroplankters. See if you can match the adult forms with their planktonic forms below.

Look up at . These are some of the planktonic organisms that are common in the Bay.

Plankton is collected with special nets like this one. The nets have tiny holes and are pulled along the water's surface.

Crabs go through metamorphosis, much like butterflies or frogs. The is one of the larval stages of crabs.

Saving and Restoring our Seagrasses

Threats to Seagrass

Nearly 80% of all in coastal Alabama have been lost since the 1950s.

A constant threat to seagrass beds is scarring created by boats' propellers and anchors. When boaters navigate across shallow areas or anchor. In seagrass beds, deep scars can form that take years to heal, leading to erosion and further seagrass loss. Poor water quality is also a significant factor that poses a serious threat to seagrass health. For example, excessive sediments in the water limit the light penetration necessary for plant survival.

How can we protect our seagrasses?

What are we doing?

To help propeller scars heal and protect seagrass beds from further scarring, local partners are implementing protection and restoration projects throughout lower , including , the island near , and .

No motor and sensitive seagrass area signs will identify seagrass beds to help boaters navigate through or around shallow water sites containing seagrass.

The scientist is using bird stakes to attract local waterfowl, whose guano deposits will provide natural fertilizer for the propeller scars, promoting the growth and expansion of surrounding seagrass.

What can you do?

Be aware of idle or raised motors and poles when navigating through shallow areas.

Set anchors in sandy areas, avoiding seagrass beds.

Obey No Motor Zone or Sensitive Seagrass areas signs: wade, troll, pole, or kayak when navigating through these areas to your favorite fishing or beach spot.

Seagrasses Coastal Nursery Habitats

What are seagrasses

Seagrasses are flowering plants that live in the shallow waters of every continent except Antarctica.

Seagrass beds containing and are found in Alabama's calm and shallow coastal waters.

Why are seagrasses important?

Seagrass beds provide food and protection for juvenile fish and shellfish, including many economically important species such as , , , and shrimp.

Many types of waterfowl feed on seagrasses, as do threatened and endangered species, such as and .

Seagrasses help stabilize bottom sediment, filter runoff, and absorb nutrients from surrounding landscapes.

Alabama's Coastal Connection

In search of food and shelter

Each fall, millions of birds leave North America and cross the Gulf of Mexico to spend the winter in South and Central America and the islands of the Caribbean. In the spring, they make the return flight to their Northern American breeding grounds. Alabama's Gulf Coast provides a critical rest stop for these travelers. Stopover areas are a key element in maintaining bird populations.

With increased development along the entire Gulf Coast, tracts of diverse, forested lands such as these are disappearing.

Migratory and resident birds use this diverse landscape for foraging, resting, and evading predators. Birds must find enough food to provide energy for the long-distance flight to nesting sites far north. Migratory butterflies depend on food such as pawpaw and passion fruit for larval growth. Songbirds feed on insects and berries, while shorebirds hunt for invertebrates in the mudflats.

The western end of the Fort Morgan peninsula is an important stopover site for migratory birds and has become a nationally known hotspot for birders. When adverse weather forces birds to the ground during a spring "fallout," the birding can be spectacular, although treacherous for the exhausted birds that must find a safe place to recover.

Commonly seen bird species during migration include vireos, warblers, flycatchers, buntings, and hummingbirds. The Monarch butterfly migration can also be breathtaking in the fall, when weather conditions are favorable.

Alabama's Coastal Connection

Permeable Parking

A better way to go

Combined sewer systems are remnants of the country's early infrastructure, and so are typically found in older communities. Combined sewer systems are designed to collect rainwater runoff, domestic sewage, and industrial wastewater in the same pipe. Most of the time, combined sewer systems convey all wastewater to a sewage treatment plant, where it is treated and then discharged into a water body. Heavy rainfall adds stormwater, causing the wastewater volume in a combined sewer system to exceed its capacity.

Combined sewer systems are designed to overflow occasionally and discharge excess untreated wastewater directly to nearby streams, rivers, or other water bodies.

These combined sewer overflows also contain untreated human and industrial waste, toxic materials, and debris.

The expansion of impermeable surfaces associated with urban sprawl and automobiles has so increased the stormwater volumes that the combined systems are being separated at great expense. The result is that stormwater runoff that used to receive treatment at the plants is now delivered to receiving streams and coastal estuaries, such as Mobile Bay.

Water running off roads, bridges, and parking lots has been estimated to be the largest source of untreated wastewater in this country. Even twenty years ago, the Federal Highway Administration estimated that 25 million tons of rubber wear off the nation's tires every week, -50 tons/week in Alabama. Since rubber is biodegradable, biodegradation consumes oxygen when it occurs in streams and estuaries. Also of concern are the heavy metals found in steel-belted radial tires, oil, antifreeze, or even transmission fluid.

The parking lot at the allows all stormwater and associated contaminants to percolate down through the gravel, providing an enormous surface area for microbial treatment of the waste, returning it to the water and carbon dioxide. Any contaminated waste that remains cannot reach the shallow freshwater aquifers that feed either the Bay or the Dauphin Island community wells because an impermeable membrane four feet down traps it and sends it through a filter system that removes the hydrocarbon contaminants. The water and any system overflows then flow into a detention pond, where vegetation, including standard cane and other plants, removes nutrients that contribute to low dissolved oxygen levels in the Bay.

Alabama Coastal Connection, Wetland Birds, Dunes, Barrier Islands & Butterflies

Wetland Birds

The feed a rich bird community. The newly created salt marsh is a prime feeding habitat for herons, egrets, pelicans, terns, sandpipers, and blackbirds. As the arch matures, the diversity and abundance of birds will increase.

At least Sandpiper (Calidris minutilla)

At low tide, the marsh brings sandpipers moving in unison across the wet sand.

Snowy Egret (Egretta thula), American Egret (Casmerodius albus), Great Blue Heron (Ardea Herodias)

The Snowy Egret, American Egret, and Great Blue Heron feed on fish and invertebrates from the marsh.

Least Tern (Sterna antillarum)

The open sand dune area provides primary nesting habitat for the Least Tern, which is threatened by habitat loss.

Brown Pelican (Pelecanus occidentalis)

Old pilings in the water provide a resting site for Southern Brown Pelicans, which were once on the brink of extinction in this area.

Ruddy Turnstone(Arenaria interpres)

Cruising along the rock is the Ruddy Turnstone. This bird turns over oysters and clam shells in search of food.

Black Skimmer (Rynchops niger)

Gifted with a graceful wing beat and beautiful coloration, the Black Skimmer grazes along the surface of the water in search of fish.

The large () to the East of the marsh are utilized for nesting by and .

Boat-tailed Grackle (Quiscalus major) Red-winged Blackbird (Agelaius phoeniceus)

Barrier Islands

Shaped by Wind and Water

Sea levels began rising 18-20,000 years ago, moving sandbars toward the mainland. The rate of rise slowed 6,000 years ago, allowing the sandbar to emerge as the present barrier islands.

Dune plants stabilize wind-blown sands, building ridges and mounds called dunes in the highest areas of the beach. Dunes are critical because, as a storm attacks a beach, water and gravity roll the sand downhill away from the dunes.

This builds an offshore sandbar, absorbing energy from the storm's waves and protecting what remains of the beaches and dune lands.

After the storm, the offshore bar provides sand for beach rebuilding.

Barrier islands perform two functions:

Barrier islands protect the mainland from erosion by absorbing much of a storm's energy.
Barrier islands trap a mixture of fresh and saltwater from the Gulf, contributing to the formation of estuaries. Coastal seafood species depend on the abundant food and brackish-water habitat that estuarine environments provide.

Alabama Coastal Connection

Dune Plants survive in a harsh environment.

Adaptation allows plants to survive salt and freshwater flooding, extreme high and low temperatures, and hurricane-force winds.

These plants reproduce from cuttings created by storms and wave action. They all rebuild the beach and dune system by trapping wind-blown sand.

Sea Rocket (Cakile constricts)

A common succulent found just above the high tide line, Sea Rocket has thick fleshy leaves to help conserve water.

Large leaf Pennywort (Hydrocotyle bonariensis)

A creeping perennial that spreads by far-reaching underground stems, Pennywort grows to about 6 inches tall and has clusters of tiny white or pale-green flowers on a 3-inch stem.

Coastal Panicgrass (Panicum amarulum)

A dense, upright perennial bunchgrass, Panicgrass helps anchor the shifting sands with deeply buried root systems.

Sea Oats (Uniola paniculata)

As the most critical and widespread grass on southern coastal dunes, the Sea Oats' recovery following storm impact is the first step in dune rebuilding.

Morning Glory (Ipomoea stolonifera)

This vine, with trumpet-shaped, white flowers, grows low to the ground, escaping the killing effects of salt spray. The stems may extend over the sand surface for 30 to 50 feet.
