The Influence Of The Wastewater Drainage From The Las Vegas Valley On The Limnology Of Boulder Basin, Lake Mead, Nevada-Arizona, James F. Labounty, Michael J. Horn, Bureau Of Reclamation

Publications (WR)

Lake Mead, Colorado River, Arizona-Nevada, is one of the most heavily used reservoirs in the western United States, providing abundant recreational opportunities as well as downstream domestic and agricultural water for over 22 million users. Based on average nutrient levels and productivity, Lake Mead is classified as mildly mesotrophic. The interflow of the Colorado River dominates the limnology of much of the 106 km-long reservoir, and may still be identified at Hoover Dam under certain conditions. The lower basin of Lake Mead ending at Hoover Dam is known as Boulder Basin and is near the Las Vegas metropolitan area. Las …

Rodent Exclusion Techniques: A Training Guide For National Park Service Employees, Gerard Hoddenbach, Jerry Johnson, Carol Disalvo

Other Publications in Wildlife Management

Rodents have been a common problem in living and working environments, probably, ever since humans began living in permanent dwellings. Even today many people believe rodent infestations are "inevitable". However, the recent appearance of Hantavirus (Sin Nombre Virus, Hantavirus Pulmonary Syndrome, HPS) in the Western states has re-awakened the public to the serious health problems posed by rodents and has prompted new inquiries into more effective ways to manage infestations. This manual is designed as a training reference for making rodent control in buildings an attainable goal.

Colby College Watershed Study: Other Area Studies

The main purpose of this study is to assess the current land use patterns and their influences on the water quality of Messalonskee Lake, including the biotic and abiotic parameters which are involved. More specifically, four main objectives were proposed. First, was to calculate the water budget and flushing rate for Messalonskee Lake. Second, was to determine the influence of current and historical land use patterns on lake water quality. Third, was to utilize gathered information to construct a phosphorus model, which will enable future water quality predictions to be made. Our fourth and final objective was to make recommendations …

Detecting Fire And Grazing Patterns In Tallgrass Prairie Using Spectral Mixture Analysis, Carol A. Wessman, C Ann Bateson, Tracy Benning

Environmental Science

Global grasslands are typically under management practices (such as fire and grazing) that alter nutrient cycling, ecosystem composition, and distribution of organic matter from the unmanaged condition. We evaluated landscape-level response to fire and grazing treatments in the Konza Tallgrass Prairie Research Natural Area, Kansas, using spectral mixture analysis of Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) data acquired 31 August 1990. Spectral mixture analysis derives the fractional abundances of spectrally unique components in the landscape. The reflectance spectra of these components are called endmembers. Endmember fractions values were compared against ground values of live biomass, current standing dead biomass, and litter …

Ecological Water Treatment System For Removal Of Phosphorus And Nitrogen From Polluted Water, Ray W. Drenner, Donald J. Day, Stacy J. Basham, J. Durward Smith, Susan I. Jensen

School of Natural Resources: Faculty Publications

We propose that phosphorus and nitrogen can be removed from polluted water using an ecological water treatment system consisting of periphyton and fish. In the proposed system, polluted water flows through a series of vessels, and the nutrients are taken up by periphyton growing on porous screens. Algal-grazing fish feed on the periphyton and either assimilate or egest the nutrients in mucus-bound feces that settle from the water into a sediment trap. Both the fish and their feces can be harvested as nutrient sinks. In this study we examined the effects of an algal-grazing cichlid (Tilapia mossambica) and …

Eastern South Dakota Wetlands, Rex R. Johnson, Kenneth F. Higgins, Michael L. Kjellsen, Charles R. Elliot

Natural Resource Management Faculty Books

Diverse and extensive wetland resources have always been familiar parts of the landscape to farmers, hunters, and residents of eastern South Dakota. The journals and oral histories of adventurers, trappers, and natives and immigrants reveal how wetlands shaped the wildlife and the people who lived on and modified the land to meet their own needs. The history of South Dakota wetlands parallels the history and interactions of people and wetlands elsewhere in North America and the world. This interaction can best be characterized as constant conflict. Driven primarily by economics, farmers the world over expended tremendous energy to "reclaim" and …

Wetland Resources Of Eastern South Dakota, Rex R. Johnson, Kenneth F. Higgins

Natural Resource Management Faculty Books

The mere mention of the word "wetland" in coffee shops and other gathering places on the prairies today brings out emotions and opinions that run the gamut from saving them all to draining them all. To some people, what we do with wetlands has been, and still is, a personal choice, a matter of exercising individual rights on private property. To others, wetlands are community resources that provide values that touch all of society. They contend that what is done to and about wetlands is a community decision regardless of ownership. Herein lies the controversy we have experienced over wetlands …

Investigation Of The Statistical And Spatial Distributions Of Mercury Contaminated Fish, Surface Waters And Soils In Arkansas, H. D. Scott, J. M. Mckimmey

Arkansas Water Resources Center Technical Reports

Mercury (Hg) contamination of fish is a widespread problem throughout much of the United States and the world (Louisiana WWW page, 1997). Levels ofHg in fish suffic1ent to exceed the FDA action level of 1 mg kg-1 have been found in many water bodies, including some in Arkansas and Louisiana. As a result of the serious public health ramifications for developing fetuses and for people that subsist on native fish, fish consumption advisories due to Hg contamination have been issued in 29 states. Contamination of surface water bodies by Hg results from deforestation, forest fires, fossil fuels, mining, natural emissions …

Fourmile Timber Sale Final Environmental Impact Statement, United States Forest Service

Final Environmental Impact Statements (ID)

This Final Environmental Impact Statement documents the analysis of four alternatives, including a "no action" alternative, that were developed for the proposed Fourmile timber sale. The sale area is on the New Meadows Ranger District of the Payette National Forest. The alternatives respond differently to the major issues and resources that were identified for this project. The purpose of the project is to improve the silvicultural conditions of timber stands in the area. Harvest emphasis to accomplish this would include removing dead, dying, and high-risk trees to improve the long term health and vigor of timber stands.

Environmental Assessment For Coal Planning Decisions In The Carbon Basin Area Of The Great Divide Resource Area, United States Department Of The Interior Bureau Of Land Management

Environmental Assessments (WY)

In 1982, a federal coal lease was issued for approximately 60% of the federal coal lands located in the Carbon Basin. Because this lease was still in effect at the time the current BLM land use plan (the Great Divide Resource Area Resource Management Plan-RMP-1990) covering the Carbon Basin area was prepared, it was exempt from the coal screening/planning requirements. However, development of this lease was never pursued and the lease expired in 1992. Also at the time the Great Divide RMP was prepared, there was no other interest expressed by industry in obtaining federal coal leases in the area. …
