A. Pervasive disturbances: The most common disturbances based on total stream length in a given region. Top five overall most pervasive disturbances to all stream reaches, regardless of stream size and across all spatial scales (ranked highest first): Crop land use Low intensity urban land use Pasture and hay land use Impervious surface cover Population density Top three most pervasive disturbances to creeks (watersheds <100 km 2 in area) across all spatial scales: Crop land use Low intensity urban land use Pasture and hay land use Top three most pervasive disturbances to rivers (watersheds >100 km 2 in area) across all spatial scales : Crop land use Impervious surface cover Pasture and hay land use Top...
Partnership - Eastern Brook Trout Joint Venture Aaron Run, in western Maryland, was once a home to Brook Trout and many other aquatic animals, but aquatic life has been seriously reduced ever since historic coal mining activities polluted the stream. A portion of the watershed sits over abandoned deep coal mines and there are several hundred acres of reclaimed surface mines in the watershed. Additionally, coal waste piles were dumped along the stream banks. Like many waters in the northeastern and Mid-Atlantic United States, acid mine drainage has severely impaired water quality of the creek causing very low pH levels, which in turn precipitated iron into the streambed, causing the creek bed to turn reddish-yellow...

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...

Most severe disturbances in the Southern Plains States associated with stream reaches being scored as having high or very high risk of habitat degradation. Disturbances are grouped into large groups (fragmentation by dams; nutrient and sediment pollution; human population; road length and crossings; water withdrawals; urban land use; agricultural land use; mines and impervious surface cover) within the four spatial scales (local catchment, network catchment, local buffer, and network buffer). Only disturbance groups that have greater than 5% of stream length in a given category are represented in this figure. Note that not all disturbance categories are available for each spatial scale; buffers have only urban...

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.
Assembling Response Data The assessment uses available fish and shellfish species presence/absence as indicators of the effects of anthropogenic (human caused) stressors on the estuarine habitats where fish and shellfish live, feed, and reproduce. Fish data were obtained from state and federal trawl survey programs, including each of the five coastal states as well as the U.S. Environmental Protection Agency’s (EPA) Environmental Monitoring and Assessment Program (EMAP) and National Coastal Assessment (NCA). Fish trawl nets are pulled through the water at specified sampling locations for a set period of time to determine the abundance and diversity of fish in the area. Environmental data like water temperature,...

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...
