    AbstractHeadwater streams dominate natural landscapes and provide essential functions for downstream waters. However, because of minimal legal protection, they often are piped or buried to accommodate urban growth. Urbanization also alters stream base flows. The combined impact of these factors on channel location is unknown. We assessed the effects of urbanization on Cited by: (floods), and has neglected low-flow events or droughts. Natural streams and rivers have stable flows for much of the time, mostly running at base flow levels [36]. Flow-generated disturbances that periodically disrupt such stable conditions may vary greatly in duration, spatial extent, and predictability. Both floods and.

Extensive modification of the landscape in the Midwestern United States, however, has profoundly affected the condition of streams. In both autumn and summer, landscape factors accounted for much of the observed variation in total dissolved solids and alkalinity.

Inthe U.S. Geological Survey (USGS) National Water-Quality Assessment Program (NAWQA) and USGS Columbia Environmental Research Center (CERC) will be collaborating with the U.S. Environmental Protection Agency (EPA) National Rivers and Streams Assessment (NRSA) to assess stream quality across the Midwestern United States.

The sites selected for Author: U.S. Geological Survey. Extensive modification of the landscape in the Midwestern United States has profoundly affected the condition of streams. Row crops and pavement have replaced grasslands and woodlands, streams have been straightened, and wetlands and fields have been drained.

These actions alter the stream habitat and add nutrients and pesticides to small streams.

Rivers and streams have many of the same economic, recreational, and environmental values and uses as lakes. However, the stresses associated with human use may have begun earlier on rivers because of their importance as transportation routes when roads were few and as sources of power when the Industrial Revolution was in its infancy in the United States.

Geological mixtures of pesticides are more complex than previously reported by the USGS—94 pesticides and 89 pesticide byproducts were detected.

The influence of environmental factors on biotic responses to nutrients was examined in three diverse agricultural regions of the United States. Seventy wadeable sites were selected along an agricultural land use gradient while minimizing natural variation within each by: Determining natural background concentrations of nutrients in watersheds in the developed world has been hampered by a lack of pristine sampling sites covering a range of climatic conditions and basin sizes.

Decades of fertilizer and manure applications have led to a buildup of phosphorus (P) in agricultural soils and sediments, commonly referred to as legacy P. Legacy P can provide a long-term source of P to surface waters where it causes eutrophication. Using a suite of numerical models, we investigated the influence of legacy P on water quality in the Yahara Watershed of Cited by: A New Flashiness Index: Characteristics and Applications to Midwestern Rivers and Streams.

Much of the impact on fresh water quality in the US comes from non-point sources, like road and agricultural runoff, with population and land use playing an important role in determining water by:   Like many other Midwestern rivers, Iowa's rivers contain diverse fish faunas, yet there is an incomplete understanding about the distribution and ecology of these fishes.

In Iowa, 44% (i.e., 68 species) of all animal species listed as species of greatest conservation need (SGCN) are fishes (Zohrer, ). This mapper provides results from the largest-ever assessment of water-quality changes in the Nation's streams and rivers.

More than million water-quality records from over Federal, State, Tribal, and local organizations were screened as part of this assessment.

The purpose of this project is to develop an integrated model that can be used to identify the least cost means of reducing agricultural NPS at the watershed level.

This will provide policy. Because of the number of factors that influence fish (dams, fishing, and pollution for example) it is difficult to evaluate the effects of a single component in the system.

Fish are not great indicators of excess sedimentation. Separating the effects of sediment from other environmental factors can be impossible in a natural system. The impacts to riparian areas are manifested in the quality of adjacent waterbodies throughout the United States.

Only about two percent of the nation’s streams and rivers are classified as having high water quality (Benke, ).

The National Rivers and Streams Assessment (NRSA) is a survey of million miles of rivers and streams in the U.S., from the largest “great river” to the smallest headwater stream.

It is part of the National Aquatic Resource Surveys, a series of statistically‐based assessments designed.
