Lower Yampa Streamflow and Sediment Modeling
Water from the Yampa River basin continues to be sought for a number of municipal, industrial, and energy uses. Water development in the Yampa River basin will alter the streamflow regime and, consequently, will lead to changes in the transport and storage of suspended and bedload sediment. Changes in the Yampa River sediment budget could lead to changes in channel geometry, riparian vegetation...
Upper Yampa Watershed Water-Quality Data
The Upper Yampa River Watershed (UYRW) drains approximately 1,798 square miles west of the Continental Divide in northwestern Colorado. The Upper Yampa River Watershed includes the Yampa River Basin upstream from Elkhead Creek and the Elkhead Creek Basin and primarily is in Routt County. The city of Steamboat Springs and the towns of Hayden, Oak Creek, and Yampa are in the watershed. The Yampa...
Aquatic communities and associated water chemistry in the St. Vrain River near the City of Longmont wastewater-treatment plant
The St. Vrain River watershed in northeastern Colorado has experienced rapid urban growth over the last two decades. Population growth has led to increased volumes being treated at wastewater-treatment plants (WWTPs) in the basin. In the last two decades, in-stream restoration efforts and new treatment technologies have been implemented by the City of Longmont, with the goal of improving water...
Blue River Water-Quality Data
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...
Water-Quality Monitoring of the Vallecito Reservoir Watershed
The water quality of the Vallecito Reservoir watershed in southwestern Colorado was initially studied by the U.S. Geological Survey (USGS) during July 1996 to July 1997, in cooperation with the Pine River Irrigation District, to assess the suitability of the reservoir as a potential source of drinking water (Ranalli and Evans, 1999). As a result of this study, in December 1997 a group of residents...
Effects of increasing urbanization on ground- and surface-water resources in the Fraser River watershed
The USGS has assessed the effects of increasing urbanization on ground- and surface-water resources in the Fraser River watershed. The population of Grand County increased 93 percent between the years of 1970 and 1990. The majority of the new development in the watershed will rely on ground water and individual septic disposal systems (ISDS's). This study has assessed the potential effects of ISDS...
