Over the course of its existence, the Town has gone from a makeshift construction camp for workers building the Dillon Dam, to a convenient refueling stop along the Interstate, to a full-service, well- balanced community of an estimated 4,100 people. The purpose of the Town of Silverthorne Community Profile is to provide current and historical information on the physical, social, and economic factors that have shaped the evolution of the Town. Information of this nature is helpful, not only for the Town government, but also for those thinking of starting a business here, relocating to the area, or for residents curious about their Town.

  • Identifying Building Sites in Summit County, Colorado: Geography, Geology, and Gis
    IDENTIFYING BUILDING SITES IN SUMMIT COUNTY, COLORADO: GEOGRAPHY, GEOLOGY, AND GIS A Thesis Presented in Partial Fulfillment for The Degree Masters of Science in The Graduate School of The Ohio State University By Kelly Ann Barrett ******* The Ohio State University 2009 Master’s Examination Committee: Dr. Douglas E. Pride, Adviser Approved by Dr. Franklin Schwartz ___________________________ Adviser Dr. E. Scott Bair Geological Science Graduate Program i ii ABSTRACT A Geographic Information System (GIS) was developed to identify future home and business sites in Summit County, Colorado, one of the fastest growing regions in the country. The permanent population is projected to be 31,500 by 2010, an increase of 25 percent from 2000 (Colorado Department of Local Affairs Demography Section). Also, in the winter the population of the county may increase to 150,000 or more during peak ski weekends (Summit County Planning Department, 2003). The county will continue development to accommodate the growing population and tourists that flock to ski resorts and other vacation facilities in this very popular and accessible region. The GIS developed here includes data for: land ownership, topography (slope and aspect), bedrock and surficial geology, soil types, presence and orientation of bedrock lineaments, locations of water wells, culture (cities, roads, emergency facilities, etc.), and city and county zoning regulations. By incorporating and correlating features of all of these, it was possible to identify areas within Summit County that can accommodate increases in permanent population and the surges that characterize the tourist industry in Colorado. Because of its location in the high country of Colorado, about 80 percent of the county (496 sq mi of a total 620 sq mi) is administered by the U.S.

    DEPARTMENT OF PUBLIC HEALTH AND ENVIRONMENT Water Quality Control Commission REGULATION NO. 71 - DILLON RESERVOIR CONTROL REGULATION 5 CCR 1002-71 [Editor’s Notes follow the text of the rules at the end of this CCR Document.] _________________________________________________________________________ 71.0 DILLON RESERVOIR CONTROL REGULATION 71.1 AUTHORITY The Water Quality Control Commission is authorized by section 25-8-205, C.R.S., to promulgate control regulations to describe prohibitions, standards, concentrations, and effluent limitations on the extent of specifically identified pollutants that any person may discharge into any specified class of state waters. 71.2 DEFINITIONS See the Colorado Water Quality Control Act and other Water Quality Control Commission regulations for additional definitions. (1) "NONPOINT SOURCE" - any activity or facility other than a point source from which pollutants are or may be discharged. (2) "DISPERSAL SYSTEM" - a system for the disposal of effluent, after final treatment in an individual sewage disposal system, by a method which does not depend upon or utilize the treatment capability of the soil. (3) “RESERVE POOL” – consists of total phosphorus credits that have not been allocated to any discharger. The source of these credits may be previous phosphorus allocations for facilities no longer in operation, reductions in existing discharger phosphorus allocations listed in 71.3, nonpoint source control projects as described in 71.5, or other sources that do not result in an increase to the total phosphorus load to Dillon Reservoir. 71.3 WASTELOAD ALLOCATION FOR TOTAL PHOSPHORUS DISCHARGE The dischargers listed below shall not discharge more than the indicated amounts of total phosphorus in any consecutive twelve month period except as provided in section 5 below.

  • Willow Creek Pumping Plant Lifts the Water 175 Feet. It Then Flows by Gravity Via the Willow Creek Feeder Canal Down to Lake Granby
    DESCRIPTION OF THE COLORADO-BIG THOMPSON PROJECT The Colorado-Big Thompson Project (C-BT) is one of the largest and most complex natural resource developments undertaken by the Bureau of Reclamation. It consists of over 100 structures integrated into a trans-mountain water diversion system through which multiple benefits are provided. The C-BT spreads over approximately 250 miles in the State of Colorado. It stores, regulates, and diverts water from the Colorado River west of the Rocky Mountains, providing supplemental water for irrigation of 720,000 acres of land east of the Rocky Mountains. It also provides water for municipal use, industrial use, hydroelectric power, and water-oriented recreation. Major features of the C-BT include dams, dikes, reservoirs, powerplants, pumping plants, pipelines, tunnels, transmission lines, substations, and other associated structures (Table 1, Exhibits 1 and 2). Historically, the C-BT has diverted approximately 230,000 acre-feet of water annually (310,000 acre-feet maximum) from the Colorado River headwaters on the western slope to the South Platte River Basin on the eastern slope, for distribution to project lands and communities. The Northern Colorado Water Conservancy District apportions the water used for irrigation to more than 120 ditches and 60 reservoirs. Twenty-nine communities receive municipal and industrial water from the C-BT. The Western Division of the Pick-Sloan Missouri Basin Program markets the electric power produced at the six powerplants. The western slope collection system captures runoff from the high mountains and stores, regulates, and conveys the water to Adams Tunnel for diversion to the east slope under the Continental Divide.

Abstracts Because of the increased demands for water in eastern Colorado, principally in the urbanizing Denver metropolitan area, increased di versionsj jof water from Oil Ion Reservoir are planned. Estimates of end-of-month storage in Dillon Reservoir, assuming the reservoir was in place and 131,000 acre-feet of water were diverted from the reser­ voir each year, were reconstructed by mass balance for the 1931-77 water years. Based on the analysis, the annual maximum end-of-month drawdown below ,,the elevation at full storage would have averaged 5k feet.
