Mississippi designated the Largemouth Bass as the official State fish in 1974, and it is the State freshwater fish in Florida, Alabama, and Georgia. The Pascagoula River is a unique resource because it is the only nearly completely free flowing (undammed) river in the region. With more than 10 cubic kilometers (2.4 cu mi) of water flowing per year into the Gulf of Mexico, it is the largest (by volume) undammed river in the contiguous 48 States. In fact, it is also the largest undammed river in the warm, humid region (Köppen climate classification zone), with southeastern Brazil claiming the second and third largest rivers in the climate zone. As a result, there continues to be a concerted effort to prevent dam construction...
The national Nonindigenous Aquatic Species (NAS) Database Program serves as a repository for geo-referenced occurrence data on introduced aquatic organisms across the nation. The NAS Program, including the database and website (http://nas.er.usgs.gov), is a well-known resource and has been widely referenced in peer reviewed literature, agency reports, state and national management plans, news articles and other locations. Access to NAS occurrence data is currently restricted to three channels: directly through the NAS website (primarily single occurrence records and species distribution maps), distributed databases (e.g, GBIF, BISON), and custom data queries directly through NAS program staff. The goal of this project...

Approximately 90 percent of the drinking water for the Washington, D.C. area comes from the Potomac River. An average of approximately 486 million gallons (1.8 million cubic meters) of water is withdrawn from the Potomac River daily in the Washington area for water supply. This is equivalent to a mid-size river with a flow of 750 cubic feet per second. At 464 miles (747 kilometers) long, the Susquehanna River is the longest river on the American east coast that drains into the Atlantic Ocean. When its watershed area is included, it is the 16th largest river in the United States and the longest river in the continental United States without commercial boat traffic today. The Susquehanna River: is almost a mile (1.6...

The Bluenose Shiner (Pteronotropis welaka) inhabits a variety of habitats from backwaters and swamps to spring-run streams. It is often found in deep pools with aquatic vegetation. Population losses have been observed where either aquatic or streamside vegetation was removed. Other threats include changes in water quality and quantity, impoundments, dredging, urbanization, and both point source and non-point source pollution.
The Ozark Cavefish (Amblyopsis rosea) is found in specific cave systems with clean flowing groundwater. These systems suffer from human use of and (or) alterations to the cave systems. Recreational cavers can damage the cave ecosystem or interrupt breeding, causing this species to leave the cave, unlikely to return. Some caves have been flooded by the creation of reservoirs or have dried up because of lowered water tables from excessive groundwater pumping or water diversion.
Reductions of flows resulting from drought and water withdrawals threaten the Fountain Darter (Etheostoma fonticola) in the headwater springs that feed the San Marcos and Comal Rivers, Texas. These are the only two places in the world this species is found. It uses dense aquatic plants and algae as habitat. It is severely threatened by the loss of vegetation caused by an exotic snail and afflicted by a parasitic non-native trematode whose life cycle uses the exotic snail as a host.
Minnesota is known as “The Land of 10,000 Lakes” and officially there are 11,842 lakes more than 10 acres (40,000 m²) in size. The prevalence of lakes has generated many repeat names. For example, there are more than 200 Mud Lakes, 150 Long Lakes, and 120 Rice Lakes. Minnesota's waters flow outward in three directions: 1) north to Hudson Bay in Canada; 2) east to the Atlantic Ocean; and 3) south to the Gulf of Mexico. Wisconsin and Michigan both have waters that flow east to the Atlantic Ocean and south to the Gulf of Mexico. Wetlands acreage present in 1850: 18.6 million acres (7.5 million hectares). Wetlands acreage present in 2008: 10.6 million acres (4.3 million hectares). Massive ice sheets at least 1 kilometer...

The Brook Trout (Salvelinus fontinalis) requires cold, clean rivers and streams. This species will move long distances to find cold water refugia and spawning habitat with upwelling groundwater, however, the species suffers from habitat degradation and watershed fragmentation. Land use changes have resulted in excessive erosion and increased water temperatures and the large number of dams and culverts in the region heavily fragment available habitat.
Two rare trout subspecies, the Apache Trout (Oncorhynchus apache) and Gila Trout (Oncorhynchus gilae), are endemic to high elevation areas of Arizona and New Mexico. They are particularly threatened by hybridization with non-native trout and devastating wildfires. Severe wildfires caused by land use changes and exotic plants result in sedimentation and ash deposition in the clear waters where they live.
The endangered Gila Chub (Gila intermedia) is found in springs and small streams of the upper Gila River basin mostly in southern Arizona but also in portions of Mexico. It prefers quiet, deep pools near cover, such as vegetation or boulders. The Gila Chub has been eliminated from 85 percent of its former range as a consequence of predation from introduced species and habitat loss resulting from water diversions, road crossings, livestock grazing, declining water quality, and groundwater pumping.
Chinook Salmon ( Oncorhynchus tshawytscha) is the largest-sized salmon species in the world and Alaska is a stronghold of self-sustaining populations. Since 2007, Chinook Salmon populations have been returning in fewer numbers to many Alaskan rivers throughout the State. This may be a result of intense fishing, poor ocean survival, and habitat loss and degradation in developing parts of the State, but because declines are so widespread, it could be a marine-derived problem. Scientists are currently working to determine the specific cause.

The Ozark Shiner (Notropis ozarcanus) requires creeks and small rivers with gravel or rocky bottoms and strong, permanent flow. The Ozark Shiner has disappeared from many stream reaches that are below impoundments and receive cold-water releases. These dams and reservoirs also serve as barriers that prevent colonization of suitable habitat. Increases in turbidity, siltation from land practices, gravel removal operations, and nutrient enrichment from poultry and swine farms are additional threats to this unique minnow species.
Hawaii is home to several unique freshwater goby species (called o`opu in Hawaiian), most of which are highly adapted and specialized to climb vertical waterfalls to get to spawning habitat. These species are under stress as the result of direct habitat loss from development and water withdrawal along with competition with non-native species and habitat fragmentation from barriers. Similarly, native prawns that are residents of enclosed brackish water bodies. known as anchialine pools, are also under stress from development pressures.

This refined map was created to help assess possible spread of nonindigenous aquatic species distributions due to flooding associated with Hurricane Harvey. Storm surge and flood events can assist expansion and dissemination of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along coastal regions. This map will help natural resource managers determine potential new locations for individual species, or to develop a watch list of possible new species within a watershed. These data include a subset of data from the Nonindigenous Aquatic Species Database, that fall within the general...
The Connecticut River is the largest river in New England. It flows 410 miles (660 kilometers) from its source to the Long Island Sound. New Hampshire and Vermont share about two-thirds of the river's length, or 275 miles (443 kilometers). The Connecticut River: is named after the Pequot word “quinetucket,” meaning “long tidal river.” The European corruption of that begat “Connecticut.” provides 70 percent of all the freshwater entering Long Island Sound. The Connecticut River has more than 1,000 dams on its tributaries and 16 dams on its main stem, 12 of which are hydropower projects. Many of these dams are more than 100 years old. The first dinosaur tracks in North America were discovered in Triassic rocks...

The Ohio River flows through or borders six States and is 981 miles (1,579 kilometers) long, starting at the confluence of the Allegheny and Monongahela Rivers in Pittsburgh, Pennsylvania, and ending in Cairo, Illinois, where it flows into the Mississippi River. At the confluence, the Ohio River is considerably bigger than the Mississippi River. More than 25 million people, almost 10 percent of the U.S. population, live in the Ohio River Basin, and it is source of drinking water for more than 3 million people even though many sections do not meet water quality standards for bacteria and pathogens, PCBs, lead, mercury, metals, organics, and other pollutants. There are 20 dams on the Ohio River that are managed by...
