2004, Fact Sheet 110-03
The Rio Grande watershed is a complex hydrologic system that includes numerous tributaries, inflow from transmountain diversions, irrigation diversions, agricultural return lows, reservoirs, and ground-water inflows and outflows. Many people depend on and are affected by the Rio Grande, which is the largest river of the surface-water system draining the...

SAM 2.1—A computer program for plotting and formatting surveying data for estimating peak discharges by the slope-area method
J.E. Hortness
2004, Fact Sheet 2004-3028
The U.S. Geological Survey (USGS) measures discharge in streams using several methods. However, measurement of peak discharges is often impossible or impractical due to difficult access, inherent danger of making measurements during flood events, and timing often associated with flood events. Thus, many peak discharge values often are calculated after...

Fort Collins Science Center: Ecosystem Dynamics
Zack Bowen
2004, Fact Sheet 2004-3147
Many challenging natural resource management issues require consideration of a web of interactions among ecosystem components. The spatial and temporal complexity of these ecosystem problems demands an interdisciplinary approach integrating biotic and abiotic processes. The goals of the Ecosystem Dynamics Branch are to provide sound science to aid federal resource...
Fort Collins Science Center: Policy Analysis and Science Assistance

2004, Fact Sheet 2004-3144
Most resource management decisions involve the integrated use of biological, sociological, and economic information. Combining this information provides a more comprehensive basis for making effective land management and conservation decisions. Toward this end, scientists in the Policy Analysis and Science Assistance Branch (PASA) of the Fort Collins Science Center (FORT)...
The importance of wood in headwater streams of the Oregon Coast Range
Christine May, Robert E. Gresswell, Janet L. Erickson
2004, Fact Sheet 2004-3055
Although headwater streams comprise the majority of stream length in mountainous regions, little is known about their form and function in comparison to higher-order rivers. A better understanding of the role of headwater streams in routing water, wood, and sediment is needed to clarify the physical and biological connections among...
Influence of forest management on headwater stream amphibians at multiple spatial scales
Margo Stoddard, John P. Hayes, Janet L. Erickson
2004, Fact Sheet 2004-3018
Background Amphibians are important components of headwater streams in forest ecosystems of the Pacific Northwest (PNW). They comprise the highest vertebrate biomass and density in these systems and are integral to trophic dynamics both as prey and as predators. The most commonly encountered amphibians in PNW headwater streams include the Pacific...
