The Eagle River drains approximately 970 square miles (sq mi) west of the Continental Divide in central Colorado before flowing into the Colorado River. The Eagle River watershed (ERW) is located primarily within Eagle County and includes the towns of Vail, Minturn, Avon, Edwards, Eagle, and Gypsum. The eastern boundary of the ERW is drained by Gore Creek, located at Vail Pass. Gore Creek flows along I-70 through the town of Vail before its confluence with the main stem Eagle River near the town of Minturn. The Eagle River continues to flow along I-70 to its western boundary near Dotsero. Increased tourism and development in Eagle County is in part due to the high mountain environment and accessible location within...

The USGS National Elevation Dataset (NED) has been developed by merging the highest-resolution, best quality elevation data available across the United States into a seamless raster format. NED is the result of the maturation of the USGS effort to provide 1:24,000-scale Digital Elevation Model (DEM) data for the conterminous US and 1:63,360-scale DEM data for Alaska. The dataset provides seamless coverage of the United States, HI, AK, and the island territories. NED has a consistent projection (Geographic), resolution (1 arc second), and elevation units (meters). The horizontal datum is NAD83, except for AK, which is NAD27. The vertical datum is NAVD88, except for AK, which is NAVD29. NED is a living dataset that...

Patterns displayed by climate forcings and hydrologic responses may be overlooked at a local scale and the co-variation of precipitation, temperature and other atmospheric conditions may not be evident until viewed from a regional spatial scale. The appraisal and management of the Nation's water resources requires the extraction of as much order and predictability from hydro-climate data as possible and thus requires a regional perspective. Temporal climate variations result from a wide range of physical, chemical, and biological processes, including chaotic or near-chaotic fluid dynamics, complex radiative and thermodynamic processes, tropical/extra-tropical interactions, ocean-air interactions, and the responses...

The UYRW is undergoing increasing land and water development to support growing municipal, industrial, and recreational needs. As development proceeds, there is the potential for short- and long-term changes in the quantity and quality of surface-water and groundwater resources. Water-quality data currently are stored in disparate formats among numerous Federal, State, and local agencies, private consulting firms, universities, and stakeholder groups. Development of a publically-accessible water-quality database (Data Repository) standardizes and unifies data from the numerous sources. These data can be used to assess water quality in the UYRW and develop a water-quality monitoring plan by identifying data gaps...

The Blue River drains approximately 680 square miles west of the Continental Divide in central Colorado before flowing northward into the Colorado River near Kremmling, Colorado. The Blue River watershed (BRW) is almost entirely located in Summit County and includes the towns of Breckenridge, Dillon, Frisco, Montezuma, and Silverthorne. Dillon Reservoir and Green Mountain Reservoir are major water storage facilities in the watershed. The BRW upstream from Dillon Reservoir is in the Colorado Mineral Belt, a zone of economically significant metals deposits. Hard-rock mining was the major industry in this area from 1859 through the first half of the 1900s. With the development of ski areas beginning in 1945 and the...
The Southwest Regional Gap Analysis Project (SWReGAP) is an update of the Gap Analysis Program’s mapping and assessment of biodiversity for the five-state region encompassing Arizona, Colorado, Nevada, New Mexico, and Utah. It is a multi-institutional cooperative effort coordinated by the U.S. Geological Survey Gap Analysis Program. The primary objective of the update is to use a coordinated mapping approach to create detailed, seamless GIS maps of land cover, all native terrestrial vertebrate species, land stewardship, and management status, and to analyze this information to identify those biotic elements that are underrepresented on lands managed for their long term conservation or are “gaps.”
The Colorado Plateau is a rugged, remote aridland region marked by a history of different land-use types and intensities. Unprecedented popularity of this region has created a demand for scientific information on which to base management and policy decisions. With the creation of the Canyonlands Research Station (CRS), a consortium of federal agencies, local governments, and regional universities have established a research facility aimed at promoting long-term ecological research, monitoring and assessment of the region.

The Upper Gunnison River Watershed, located in the Rocky Mountains 150 miles southwest of Denver, Colorado, drains approximately 3,965 square miles. Forest and rangeland comprise 89 percent of land within the watershed, but the traditional western ranching economy is increasingly supplemented through a tourism economy centered around Crested Butte Mountain Resort and the Curecanti National Recreation area. Recreational development and population growth in recent years have the potential to affect both the quantity and quality of water.
This interactive workshop was designed to provide background information and stimulate discussion on the effects of climate variability, possible natural and human-related long-term climate change, and land-use change in the rapidly-growing southwestern United States. This information will be used by the U.S. Global Change Research Program as part of a national assessment of Global Change issues. This web conference was open for interactive participation from Monday, July 7 through Friday, July 25, 1997. The articles and comments will remain available indefinitely.
An online decision support tool for managers, planners, conservation practitioners and scientists.The models generating these maps are the first to take into account the ability of marshes to accrete, or keep up with, rising sea levels, in the San Francisco Bay Estuary.PRBO has generated a series of scenarios to provide a range of projections to address the uncertainty in future rates of sea-level rise and suspended sediment availability.Our maps cover the entire Estuary allowing for analyses at multiple spatial scales.This tool displays maps created at a high spatial resolution using the best available elevation data. The website will be continually updated as new data becomes availableThe tool is the first to...
The Northwest Regional Gap Analysis Project (NWGAP) is an update of the Gap Analysis Program's mapping and assessment of biodiversity for the five-state region encompassing Washington, Idaho, Oregon, Montana, and Wyoming. It is a multi-institutional cooperative effort coordinated by the U.S. Geological Survey Gap Analysis Program. The primary objective of the update is to use a coordinated mapping approach to create detailed, seamless GIS maps of land cover, all native terrestrial vertebrate species, land stewardship, and management status, and to analyze this information to identify those biotic elements that are underrepresented on lands managed for their long term conservation, in other words, "gaps". This...
This page catalogs known dust storm events that we have captured using various techniques and imaging platforms.
A key task was the development of a seamless land stewardship map for the region. Through coordination from the U.S. Geological Survey’s Gap Analysis Program (GAP) and the collaborative efforts of participating state institutions, a seamless product was completed in September 2005. These data are made available to the public by the SWReGAP consortium of institutions responsible for their development. The two primary goals of GAP are to provide an assessment of the management status for certain elements of biodiversity (vegetation communities and animal species) throughout their U.S. range, and to provide land stewards with information on the representation of these elements on their land so they can make informed...
The U.S. Geological Survey (USGS) conducted an Abandoned Mine Lands (AML) Initiative during the fiscal years 1997 through 2001 to provide technical assistance in support of Federal Land Management Agency (FLMA) actions to remediate contamination associated with abandoned hard rock mining activities. This initiative was part of a larger strategy by the U.S. Department of the Interior and the U.S. Department of Agriculture to coordinate activities for the cleanup of federal lands affected by AML. The strategy employed a watershed approach, in which contaminated sites were identified and remediated based on their effect on the water and ecosystem quality of a targeted watershed. The initiative was implemented on a...

Multi-season satellite imagery (Landsat ETM+) from 1999-2001 were used in conjunction with digital elevation model (DEM) derived datasets (e.g. elevation, landform, aspect, etc.) to model natural and semi-natural vegetation. Landcover classes are drawn from NatureServe's Ecological System concept, with 109 of the 125 total classes mapped at the system level. For the majority of classes, a decision tree classifier was used to discriminate landcover types, while a minority of classes (e.g. urban classes, sand dunes, burn scars, etc.) were mapped using other techniques. Twenty mapping areas, each characterized by similar ecological and spectral characteristics, were modeled independently of one another. These mapping...
Snowpacks collect atmospheric deposition throughout the snowfall season and offer a unique opportunity to obtain a composite sample of the chemistry of most of the annual precipitation at high-elevations (> 1800 meters). The purpose of the snowpack network is to determine annual concentrations and depositional amounts of selected nutrients and other constituents in snow resulting from atmospheric deposition, determine long-term trends in these concentrations, and to support investigations of impacts of atmospheric deposition on local and regional ecological systems. During the past 17 years, the project has become the most expansive and comprehensive snowpack-chemical monitoring network of its kind.
