Unified Interior Regions

Colorado

The Rocky Mountain Region ranges from the Colorado Rockies to the Western Deserts to the Great Plains. The Rocky Mountain Region conducts multi- and interdisciplinary research and monitoring in locations across the Region, the United States, around the world, and across our solar system.

National water summary 1987: Hydrologic events and water supply and use

Water use in the United States, as measured by freshwater withdrawals in 1985, averaged 338,000 Mgal/d (million gallons per day), which is enough water to cover the 48 conterminous States to a depth of about 2.4 inches. Only 92,300 Mgal/d, or 27.3 percent of the water withdrawn, was consumptive use and thus lost to immediate further use; the...

Estimated use of water in Colorado, 1985

Water-use data was collected for the State of Colorado as part of the U.S. Geological Survey 's National Water-Use Information Program. An estimated 20,800 million gal/day of water were used in Colorado during 1985. 89% came from surface water sources and 11% came from groundwater sources. Public supply systems provided 4% of all water used in...

Estimating pumping time and ground-water withdrawals using energy- consumption data

Evaluation of the hydrology of an aquifer requires knowledge about the volume of groundwater in storage and also about the volume of groundwater withdrawals. Totalizer flow meters may be installed at pumping plants to measure withdrawals; however, it generally is impractical to equip all pumping plants in an area with meters. A viable alternative...

Evapotranspiration estimates using remote-sensing data, Parker and Palo Verde valleys, Arizona and California

In 1981 the U.S. Geological Survey established an experimental project to assess the possible and practical use of remote-sensing data to estimate evapotranspiration as an approximation of consumptive use of water in the lower Colorado River flood plain. The project area was in Parker Valley, Arizona. The approach selected was to measure the areas...

Leopard frog and wood frog reproduction in Colorado and Wyoming

Between 1978 and 1988, we recorded reproductive information from populations of ranid frogs in Colorado and Wyoming. Egg masses from five plains and montane populations of northern leopard frogs (Rana pipiens) contained 645-6272 eggs (x̄ = 3045, N = 68 egg masses). In two montane populations of wood frogs (Rana sylvatica) numbers of eggs per egg...

Water-quality data-collection activities in Colorado and Ohio; Phase I, Inventory and evaluation of 1984 programs and costs

Pilot projects are being conducted in Colorado and Ohio to determine the extent to which existing water quality data, collected by different groups for various purposes and using different procedures, can be aggregated for use in addressing selected water quality questions of regional and national scope. The project has been divided into three...

Characterization of floodflows along the Arkansas River without regulation by Pueblo Reservoir, Portland to John Martin Reservoir, Southeastern Colorado

The need for a method for estimating flow characteristics of flood hydrographs between Portland, Colo., and John Martin Reservoir has been promoted with the construction of the Pueble Reservoir. To meet this need a procedure was developed for predicting floodflow peaks, traveltimes, and volumes at any point along the Arkansas River between...

Reservoir analysis of the Denver earthquakes: A case of induced seismicity

Injection of fluid wastes into the fractured Precambrian crystalline bedrock beneath the Rocky Mountain Arsenal near Denver triggered earthquakes in the 1960's. An analysis, based on the assumption that fluid flow in the fractured reservoir can be approximated by flow in a porous medium, is presented. The configuration and hydrologic properties of...

Transit losses and traveltimes of reservoir releases along the Arkansas River from Pueblo Reservoir to John Martin Reservoir, southeastern Colorado

The need for accurate information regarding the transit losses and traveltimes associated with releases from Pueblo Reservoir has been stimulated by construction of the U.S. Bureau of Reclamation's Fryingpan-Arkansas Project and a proposed winter-water storage program in Pueblo Reservoir. To meet this need, the U.S. Geological Survey, in...

Hydrologic effects of reducing irrigation to maintain a permanent pool in John Martin Reservoir, Arkansas River Valley, Colorado

The U.S. Geological Survey has evaluated a plan by the Colorado Division of Wildlife to maintain a permanent pool of 10,000 acre-feet (1.2x107 cubic metres) in John Martin Reservoir on the Arkansas River. The proposed pool would be maintained through the use of water formerly diverted by the Catlin Canal Company to irrigate land in the Arkansas...
