on the quality of 70 midwestern streams and rivers was evaluated in the Upper Mississippi River (UMIS), Eastern Iowa (EIWA), and Lower Illinois (LIRB) River basins. Streams with less tree cover, and thus less shading, contained relatively large growths of phytoplankton (algae suspended in the water) at levels con-sidered indicative of.
The Midwest Stream Quality Assessment—Influences of Human Activities on Streams. Printed on recycled paper. Healthy streams and the fish and other organisms that live in them contribute to our quality of life.
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.
During autumn, geological factors and the shared influence of geology/landscape structure plus land use exerted more influence than did land use alone. by: Factors influencing growth of individual brown trout in three streams of the upper Midwestern United States Article (PDF Available) in Ecology of Freshwater Fish.

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.

Roley, The Influence of Two‐Stage Ditches with Constructed Floodplains on Water Column Nutrients and Sediments in Agricultural Streams, JAWRA Journal of the American Water Resources Association, 51, 4, (), ().Cited by: More than pesticides and their by-products were detected in small streams throughout 11 Midwestern states, some at concentrations likely to harm aquatic insects, according to a new study by the U.S.
Geological mixtures of pesticides are more complex than previously reported by the USGS—94 pesticides and 89 pesticide byproducts were detected. Water-chemistry, biological, and habitat data were collected from 70 sites on Midwestern streams during August as part of an integrated, regional water-quality assessment by the U.S.
Geological Survey National Water-Quality Assessment (NAWQA) Program. The study area includes the Corn Belt region of southern Minnesota, eastern Iowa, and west-central Illinois. 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.
Using data from 63 minimally impacted U.S. Geological Survey reference basins, we developed empirical models of the background yield of total nitrogen (TN) and total Cited by: Understanding Our Streams and Rivers Page 1 of 4 Just as our human health is determined by the factors that inﬂ uence our bodies, including environment, lifestyle, and healthcare, so too is stream health determined by the combined factors of the stream’s conﬁ guration, environment, resil-ience, and our Size: KB.
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. Journal of the American Water Resources Association (JAWRA) 40(2) INTRODUCTION Streamflows vary in characteristic ways over time frames ranging from hours and days to seasons and years.
The pattern of this variation is referred to as. Introduction. Glyphosate is the most widely used herbicide, both in terms of mass and geographic distribution, in the United States (US). An estimated million kg of glyphosate was used for both agricultural and non-agricultural applications during (Benbrook, ).Since the advent of glyphosate tolerant crops such as corn, cotton, and soybeans in the mid s Author: Laura Medalie, Nancy T.
Baker, Megan E. Shoda, Wesley W. Stone, Michael T. Meyer, Edward G. Stets, M. Introduction. Many natural and anthropogenic factors affect the geochemistry of surface waters in both rural and urban areas. 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. Tan, Jing, "Estimating the water quality condition of river and lake water in the Midwestern United States from its spectral characteristics" ().
Open Access Dissertations. Author: Jing Tan. AbstractTemperature is a primary driver of the structure and function of stream ecosystems.
However, the lack of stream temperature (ST) data for the vast majority of streams and rivers severely compromises our ability to describe patterns of thermal variation among streams, test hypotheses regarding the effects of temperature on macroecological patterns, and assess the Cited by:.

EPA, Office of Research and Development in Corvallis, OR; Duluth, MN; Las Vegas, NV Colorado Division. Among the sources affecting the quality of water, Non-Point Source (NPS) pollution from agricultural lands incurs substantial damage to both on-site and off-site locations. 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.
