Fire On The Mountain: Growth And Conflict In Colorado Ski Country, Michael W. Childers May 2010

Fire On The Mountain: Growth And Conflict In Colorado Ski Country, Michael W. Childers

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation examines the environmental, economic, and cultural conflicts over the private development of ski resorts in Colorado's National Forests between 1910 and 2000. Downhill skiing emerged as an increasingly popular winter activity during the first half of the twentieth century, particularly in western state such as Colorado. A part of the a larger outdoor recreational boom throughout the United States' during the interwar years, downhill skiing challenged the Forest Service's ability to meeting the public's growing appetite for year-round recreational opportunities. These challenges increased following World War II as the nation's growing population and affluence drew millions to their …


Synthetic Organic Compounds: Las Vegas Wash And Lake Mead, National Water Quality Assessment Program (Nawqa): Nevada Basin And Range Jan 1996

Synthetic Organic Compounds: Las Vegas Wash And Lake Mead, National Water Quality Assessment Program (Nawqa): Nevada Basin And Range

Publications (WR)

The Nevada Basin and Range (NVBR) study unit of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program is investigating the status of, trends in, and factors affecting water quality in the Las Vegas area. A principal objective of the investigation is to assess the effects of urbanization on the quality of area water resources.

Las Vegas Wash is the surface-water outlet for the Las Vegas area. The wash transports stormwater runoff, shallow ground-water discharge, and tertiary-treated sewage effluent from the Las Vegas area to Las Vegas Bay of Lake Mead on the Colorado River. Most of the flow—about 96 …


Analysis Of The Water-Quality Standards Proposed By The Nevada Division Of Environmental Protection, City Of Las Vegas, Nevada Aug 1987

Analysis Of The Water-Quality Standards Proposed By The Nevada Division Of Environmental Protection, City Of Las Vegas, Nevada

Publications (WR)

The Nevada Division of Environmental Protection (DEP) has proposed water-quality standards, applicable to Las Vegas Bay and Lake Mead, for (1) chlorophyll, (2) un-ionized ammonia, and (3) pH.

We have concluded that the proposed standards are unlikely to protect or improve water quality in Lake Mead. The proposed chlorophyll standard:

May harm the fishery. Lakes with more chlorophyll have greater fish production.

Will not improve clarity. Chlorophyll concentrations above 30 ug/1 have little effect on clarity.

Will not protect against scums or dominance by blue-green algae. Lake Mead shows no consistent relationship between chlorophyll and scums or blue-green dominance.

Will …
