Nutrient and Suspended-Sediment Trends in the Missouri River Basin, 1993-2003 Nutrient and Suspended-Sediment Trends in the Missouri River Basin, 1993-2003
Trends in streamflow and concentration of total nitrogen, nitrite plus nitrate, ammonia, total phosphorus, orthophosphorus, and suspended sediment were determined for the period from 1993 to 2003 at selected stream sites in the Missouri River Basin. Flow-adjusted trends in concentration (the trends that would have occurred in the absence of natural changes in streamflow) and non-flow...

Effects of urban development on stream ecosystems alongthe Front Range of the Rocky Mountains, Colorado and Wyoming Effects of urban development on stream ecosystems alongthe Front Range of the Rocky Mountains, Colorado and Wyoming
The U.S. Geological Survey (USGS) conducted a study from 2002 through 2003 through its National Water-Quality Assessment (NAWQA) Program to determine the effects of urbanization on the physical, chemical, and biological characteristics of stream ecosystems along the Front Range of the Rocky Mountains. The objectives of the study were to (1) examine physical, chemical, and biological...

Effects of urbanization on stream ecosystems in the South Platte River basin, Colorado and Wyoming Effects of urbanization on stream ecosystems in the South Platte River basin, Colorado and Wyoming
This report describes the effects of urbanization on physical, chemical, and biological characteristics of stream ecosystems in 28 basins along an urban land-use gradient in the South Platte River Basin, Colorado and Wyoming, from 2002 through 2003. Study basins were chosen to minimize natural variability among basins due to factors such as geology, elevation, and climate and to maximize...

Drought effects on water quality in the South Platte River Basin, Colorado Drought effects on water quality in the South Platte River Basin, Colorado
Twenty-three stream sites representing a range of forested, agricultural, and urban land uses were sampled in the South Platte River Basin of Colorado from July through September 2002 to characterize water quality during drought conditions. With a few exceptions, dissolved ammonia, Kjeldahl nitrogen, total phosphorus, and dissolved orthophosphate concentrations were similar to seasonal...
