Michigan, Wisconsin, and Minnesota border four of the five Great Lakes (lakes Michigan, Superior, Huron, and Erie) and have over 150,000 miles of rivers and streams and 50,000 inland lakes within their boundaries. The upper Mississippi River flows through the Upper Midwest states, from its headwaters in Minnesota along the boundary between Minnesota and Wisconsin. Much of the region has deep glacial deposits which has a tremendous influence over the habitat types and water flow (hydrology), providing for some of the most stable river flows in the United States. An exception to the glaciated region is a unique region of deeply carved unglaciated river valleys known as “The Driftless Area” which located in southwestern...

Most of Alaska has an abundance of unaltered clean fresh water habitat that maintain remarkable self-sustaining fish populations requiring water flows in the proper amount at the right time. These habitats face an increasing number of demands. New hydroelectric projects, such as the recently proposed Susitna-Watana Hydroelectric Project, and the expansion of existing projects can, if not very carefully sited and designed, increase barriers to fish migration and create adverse hydrologic and sediment effects on streams that provide critical spawning and rearing habitat for self-sustaining salmon populations. These potential barriers are not just an issue for fish but the entire ecosystem as everything from trees...

Major cities, such as Detroit, Milwaukee, Minneapolis/St. Paul, and numerous smaller lakefront cities support a population of over 21 million people in the Upper Midwest area. Converting land to urban areas has reduced fish habitat through the filling of wetlands, altered rivers and streams to convey artificially-caused high-flow events through these areas, decreased the streams ability to meander, and has converted natural lake shorelines to bulkheads and seawalls. Many parcels of private land in the forested portions of this region: are being sold for development of subdivided vacation communities; have impoundments developed on free flowing streams to create “new” lakefront properties; and are seeing a rapid...

While fish habitat was found to be generally to be at very low or low risk of degradation in this mostly arid western region of the United States, water availability (hydrology – a key fish habitat process and driver of fish habitat) could only be partly examined using the available datasets in this Assessment. The lack of information on the status of water flow in many basins has led them being overestimated in fish habitat quality, even if streams in these basins are actually dry most of year. Additionally, data availability for grazing intensity, another key landscape use, is also unavailable, and has also created situations where the Assessment overestimates habitat quality. Despite such absences, impairment...

Forty-three percent of the surface area of Alaska is wetlands. On a state-wide basis, less than 2 percent of all wetlands have been developed. However, in many developing areas and communities, wetlands may be the only land type available for development. In urbanized and developed areas of Alaska, such as the Anchorage Bowl, it is estimated that over half of the wetlands have been lost to transportation corridor construction, utility installation, buildings, and other development projects. Wetland loss fragments habitat and disrupts migration of fish that use wetlands as resting places on their lengthy migrations, and it is also critical rearing habitat for young salmon. Wetland loss is also linked to altered native...

Partnerships - Atlantic Coastal Fish Habitat Partnership, Reservoir Fish Habitat Partnership, and Southeast Aquatic Resources Partnership Almost 10,000 ft (over 15,000 plantings) of native mangrove and salt marsh plants, as well as oyster shells were put in the Atlantic-side estuaries of Florida. These plantings helped to stabilize sediment and shoreline, improve water clarity, provide nesting areas for birds such as the Roseate Spoonbill, and provide habitat for species such as Red Drum, Tarpon, Mangrove Snapper, and snook. In addition, five acres of invasive Brazilian pepper trees were removed to allow for native plantings. Fish Habitat Partnerships provided funding for: the creation of 750 acres of wetland,...

Urban areas significantly and negatively affect aquatic habitat quality in the Mountain States. This was particularly apparent in the rapidly growing Denver/Ft. Collins, Boise, Salt Lake City, Great Falls, and Billings areas. Highway corridors along Interstates 25 and 90 in Wyoming and 76 in Colorado were implicated to be causing high to very high risk factors. In 2015, the highly urbanized I-25 corridor between Cheyenne, WY and Pueblo, CO had a population of 4.49 million people. In these cities and their surrounding suburbs, large areas of impervious surfaces (i.e. buildings, parking lots, and roads) replace natural streamside habitat, increase pollution and sedimentation, alter hydrology, and increase the demand...

A greater percentage of Alaskan residents fish (53 percent in 2011) than residents of any other State. Alaska’s largest private sector employer is commercial fishing with total annual landings of fish products of 79 billion pounds (36 million metric tons). Nearly all of these fish are from self-sustaining populations. In 1867, the United States Secretary of State William H. Seward offered Russia $7,200,000, or two cents per acre, for Alaska. The State of Rhode Island could fit into Alaska 425 times. Most of America's salmon, crab, halibut, and herring come from Alaska. The State's coastline extends more than 6,600 miles. Alaska is the largest State in the United States and is more than twice the size of Texas.

A major hub for manufacturing and transportation, the Great Lakes and their tributaries were once an easy dump site for their waste products that included organic toxins, mercury, PCBs, and dioxins. As a result of the Federal Clean Water Act (1972) most of the direct pollution discharges from known point sources have stopped, but the legacy pollutants remain because many are trapped in lake and stream sediments. Other dissolved pollutants have long residence times because less than one percent of the water in the Great Lakes exits the lake system annually. Discharge from sewage treatment systems remains a problem, particularly where stormwater and sewage systems are combined in large urban areas. The inland fish...

A significant number of dams are located in Iowa (> 4,000), Illinois (> 1,759), Indiana (> 1,088) and Ohio (> 2,600). Dams in the Central Midwest were built to provide mechanical power for mills, hydropower, recreation, water supplies, and water retention for urban and agricultural use. Nearly all of these dams impede fish movements in the region and particularly in the Mississippi River drainage and in the watershed of lakes Erie and Michigan. Some communities are removing dams to deal with obsolete infrastructure issues and to improve water quality, flow, and stream connectivity. For example, the removal of Black Berry Creek Dam near Aurora, Illinois in 2013 opened up 32 miles of the Fox River for fish spawning...

The saltwater triggerfish, humuhumunukunukuapua'a, is Hawaii's State fish and is well known for its long name. Hawaii is the only State in the United States with a tropical rain forest. Hawaii is the most isolated population center on the face of the earth. Hawaii is 2,390 miles (3,846 kilometers) from California; 3,850 miles (6,196 kilometers) from Japan; 4,900 miles (7,886 kilometers) from China; and 5,280 miles (8,497 kilometers) from the Philippines. The Waialua River is one of five navigable rivers in Hawaii. It drains off Waialeale Mountain, which averages 488 inches (1,240 centimeters) of rain per year and is considered the wettest spot on earth. Honolulu is the largest city in the world (it has the longest...

The southeastern states contain the rapidly growing urban centers of Atlanta, Greenville, Columbia, Charlotte, and Winston-Salem/Raleigh with suburban corridors between them. In these cities and the surrounding suburbs, large areas of impervious surfaces replace natural streamside habitat, increase pollution and sedimentation, and alter water flow (hydrology). In this 2015 assessment, land cover type was estimated to be a major risk factor for about one-third of the estuaries of the Southeastern states. The United States Department of Agriculture reports that from 1982 to 2012 over 2.6 million acres of rural land in Georgia was developed. Development in North Carolina was almost as high, while South Carolina lost...

Miami, Tampa, Orlando, and Jacksonville rank in the top 50 largest cities in the nation by area. Atlanta and New Orleans are the only other top 50 cities in the Eastern Gulf States region. These four Florida urban centers anchor what is known as the Florida Megaregion, one of eleven recognized in the United States. New Orleans and Baton Rouge are part of the Gulf Coast Megaregion. The growing urban sprawl throughout the Gulf States leads to increasing areas of impervious surface, which results in altered water flows and more urban runoff that transports high levels of nutrients and pollution to aquatic resources. For example in central Mississippi, pathogens, litter/trash, nutrients, and pesticides from increasing...

Partnerships - Driftless Area Restoration Effort, Great Lakes Basin Fish Habitat Partnership, Ohio River Basin Fish Habitat Partnership, Reservoir Fisheries Habitat Partnership, and Fishers and Farmers Partnership Restored 738 acres of wetland and over 400 feet of stream habitat in Ohio. Removed 1 barrier in Iowa that reconnected 69 miles of stream habitat for Smallmouth Bass and many coolwater species. Restored 1750 feet of shoreline and added 100 feet of structure to lake shorelines in Illinois. Augmented three mussel populations on four Indiana rivers, giving two federally-endangered species a new foothold in the basin. Launched a basin-wide mussel initiative to identify and address stressors in quality streams...

The Delta Smelt (Crystallaria asprella) is only found in the Sacramento - San Joaquin River Delta in California and requires estuaries for juvenile and adult habitat along with the ability to migrate into tributary rivers to spawn in the spring. Declines of Delta Smelt can largely be attributed to the changes and fluctuations in flow of the estuarine ecosystem. Reduced flows resulting from water projects have resulted in saltwater intrusion into the Delta, which has reduced the amount of preferred habitat for spawning and nursery areas. When increased amounts of water are released by the water projects, larvae and adults become entrained and die, and both the fish themselves and the food they depend on are washed...

The Bull Trout (Salvelinus confluentus) is widely distributed within the region and occupies a variety of large lakes, small headwater streams and larger river systems. Of all the native salmonids in the Pacific Northwest, the Bull Trout generally has the most specific habitat requirements, which are often referred to as “the four Cs”: cold, clean, complex, and connected habitat. In November 1999, the U.S. Fish and Wildlife Service listed all Bull Trout populations within the lower 48 States of the United States as threatened pursuant to the Endangered Species Act. The U.S. Fish and Wildlife Service’s 2015 Bull Trout Recovery Plan lists historical habitat loss and fragmentation; interactions with nonnative species...

Partnerships - Eastern Brook Trout Joint Venture, Great Lakes Basin Fish Habitat Partnership and Atlantic Coastal Fish Habitat Partnership Almost 32 miles of streams and 260 acres of riparian habitat were rehabilitated to improve Eastern Brook Trout habitat. Nearly 800 feet of riverine bottom in Maine was restored to improve spawning habitat for diadromous fish. Two acres of oysters were installed in the Great Bay Estuary (310,000 spat) to stabilize sediments, improve water quality, and provide habitat for species such as river herring, Atlantic Tomcod, Winter Founder, and Striped Bass. Partners removed or improved 46 barriers, which allowed inland and diadromous fish to access an additional 108 miles of riverine...

The Greater Redhorse (Moxostoma valenciennesi) is sensitive to habitat changes, particularly excessive siltation, and pollution. Other threats include river channelization, alterations to flow regimes, dam construction, and removal of riverside vegetation. Barriers are especially problematic as this is a wide-ranging species that has different flow and habitat requirements for different stages of development.

The Chesapeake Logperch is native to Maryland and Pennsylvania; populations in Virginia have been extirpated. It requires rocky habitat in larger rivers and is listed as imperiled. This species has suffered from water quality and habitat degradation in the larger rivers in Mid-Atlantic States with mining, agriculture, and wastewater discharges, which causes elevated metal concentrations, suspended solids, nutrient loading, pH, and high oxygen demand in river waters.
