Las Vegas Wash, a natural wash east of the city of Las Vegas, Nevada, carries stormwater, groundwater drainage, and sewage effluent from three sewage treatment plants to Lake Mead. The Wash provides nearly the only surface water outlet for the entire 2,193 mi2 of Las Vegas Valley. A drainage area of 1,586 mi2 contributes directly to the Wash through surface flow which is channeled to Las Vegas Bay of Lake Mead, while drainage of the remaining 607 mi2 is presumably subsurface and may drain toward Las Vegas Wash.
In the 1930's and 1940's, sewage treatment plants were …

Bulletin 4333 - Furrow Sowing On Water Repellent Soils, Paul Blackwell, Grant Morrow
Bulletins 4000 -
This Bulletin discusses the benefits that furrow sowing brings to crop growth and production on water repellent sand, based on research and farm observations in Western Australian. By understanding the benefits and risks of several key processes, producers can better evaluate the potential role of furrow sowing in combating water repellency. This is true whether one is using direct drilling, no-till (narrow points or discs) or zero till (single, double or triple disc openers) methods.

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 …

Massachusetts Angler Typologies: The Recreation Specialization Approach, Jonathan S. O'Neil
Marine Affairs Theses and Major Papers
As the abundance of fish stocks in the Northeast continues to decline, the need to regulate the marine recreational catch is a topic receiving much attention. Yet, the move to manage recreational anglers' fishing activities raises a host of new questions. How should the resource be allocated among different groups of fishermen? Which group should take precedence over others; or should resources be divided equally among all? To manage the Massachusetts recreational fishery, many of these questions will have to be answered to ensure the success of conservation goals. With a comprehensive understanding of anglers and their relationship to fishery …

Toolibin Catchment Revegetation Manual, Avril Baxter
Natural resources published reports
In1983, heavy winter rains resulted in severe inundation and flooding of the lower parts of the Toolibin catchment. The damage to crops and pastures was immense and costly. Local farmers realised that they needed to work together to minimise the impact of heavy rainfall events on their farm productivity.
At the same time the Western Australian Department of Conservation and Land Management (CALM) was concerned about the quality of both ground and surface water in the catchment area for Toolibin Lake, the last remaining wooded freshwater lake in the southern wheatbelt. This mutual interest led to the formation of the …

Algal bioassay tests were conducted with Selenastrum capricornutum and natural algae on inner Las Vegas Bay, Lake Mead, Nevada, from December 1992 through September 1993, to identify any nutrient limitation in an area of the reservoir that has experienced problems associated with severe nutrient enrichment. Three areas were sampled based on a gradient of water quality conditions that existed in Las Vegas Bay (LVB). Disodium ethylenedinitrilotetraacetate (EDTA) significantly stimulated algal growth compared to non-EDTA treatment. Algal bioassays indicated that phosphorus (P) was the primary limiting nutrient at all stations for most of the test dates. Chl a response with EDTA …

Limiting Growth In Las Vegas - A Necessary Growth Strategy For The Twenty-First Century, Cheryl Ann Frassa
UNLV Theses, Dissertations, Professional Papers, and Capstones
Land development in the Las Vegas Valley continues at an unprecedented rate and future growth will no doubt be strongly advocated. Yet, water resources in this desert area are finite, and in the near future, supply will fall short of demand. Plans are underway to supplement the existing supply, and proposals to secure additional sources are under investigation. But there are no guarantees these ambitious endeavors will materialize. In light of the pending water crisis, the pervasive "growth at all cost" policies now dominant in the valley must be abandoned and more realistic land-use policies developed; ones based on the …

Water Resources Studies Along The Arkansas-Oklahoma Border, Kenneth F. Steele
Arkansas Water Resources Center Technical Reports
The watershed approach to water resource issues recently has been re-discovered. Scientists and managers recognize the need to consider the entire watershed when delineating and solving today's water resource problems. A simple example is the effect that streams have on the ultimate "health" of a reservoir. Although technically the term watershed should be used only in reference to surface water, the importance of ground water is included in the watershed approach to problems. In recognition that we all "live upstream and downstream," the Arkansas Water Resources Center and the Oklahoma Water Resources Institute sponsored a conference titled "Water Resource Studies …
The National Estuary Program's Watershed Protection Approach: An Analysis Of Local Governments, Constituency Organizations And Watershed Residents In Addressing Nonpoint Source Pollution In The Buzzards Bay Project, Paula Renier Jewell
Marine Affairs Theses and Major Papers
Reduction of coastal nonpoint source (NPS) pollution requires an innovative approach. Efforts must comprehensively address the cumulative effects of individual behaviors. Therefore, program objectives must apply to the entire contributing watershed, but emphasize local implementation. Local governments must be empowered to install regulatory and other mechanisms to reduce NPS pollution. Local citizen organizations such as watershed associations, must effectively educate watershed citizens about their ole in NPS pollution. Watershed citizens must change their behaviors which contribute to the problem. However, developing a vibrant constituency around NPS pollution itself remains a serious challenge to mitigation efforts. As a geographically defined, holistic …

A network of over 1400 kilometres of drains and modified natural waterways constructed by the Public Works Department criss-crosses the Peel-Harvey catchment. There are also over 3300 kilometres of minor drains and natural waterways in this same region.
The expansion of agriculture relied on this extensive drainage network, which was designed to ensure rapid drainage of the region. Unfortunately there was little regard to future environmental consequences.
Along with drainage water, these same drains now carry high loads of silt and nutrients. Many of the drains are also degraded and require expensive maintenance annually.

Conservation And Management Of Sri Lanka's Coastal Resources Through The Experience Of Other Countries, K.W.P. Thilakaratna
Marine Affairs Theses and Major Papers
After Sri Lanka's independence in 1948, the economic importance of the coastal areas had intensified due to development of commercial and fishery harbors, transportation, communication, and recreational facilities. Opportunities in the public administration, industry, and education sectors were other main attractions. With the introduction of international tourism in 1970, economic development of coastal areas increased further. In addition to the job opportunities provided by the industrial and commercial sectors, many people were engaged in other activities depending on coastal resources, including fishing and mining activities. Prior to 1978, there was no proper authority or mechanism to address coastal issues. legislation …

Southern Nevada Effluent Wetlands: A Proposed Cooperative Venture Between The Bureau Of Reclamation & City Of Las Vegas, Bureau Of Reclamation
Publications (WR)
Throughout North America there is a growing interest in constructed wetlands, both as relatively inexpensive, low-maintenance systems for removing nutrients from wastewater, and as a means of using municipal wastewater to enhance wildlife habitat and create public use opportunities. Because wetlands appear to have good potential as a component in the overall management of scarce water resources, the Bureau of Reclamation (Reclamation) has undertaken several cooperative research and demonstration projects to evaluate their effectiveness in a variety of local environments. While a number of projects have demonstrated that wetlands can be beneficially employed to improve water quality, few such projects …
Mitigation Banking: A Potential Tool For Port Planners, Laura Kelley
Mitigation Banking: A Potential Tool For Port Planners, Laura Kelley
Marine Affairs Theses and Major Papers
Mitigation banking has been used as a means of facilitating the permit process by removing the negotiation of appropriate mitigation for development from the confines of the permit process. A developer with frequent needs to mitigate for losses associated with Section 404 and Section 10 requirements may, using a mitigation bank, consolidate mitigation and in so doing, potentially reduce mitigation costs. As a result of route maintenance, as well as expansion requirements, ports were considered to be good candidates for sponsoring mitigation bank efforts. Port use of mitigation banking has not been as expected due to a lack of available …

Marine Affairs Theses and Major Papers
Browning Beach is situated on the south shore of Rhode Island just to the west of Matunick. Midway along the barrier beach connecting Green Hill Point and Matunick Point is a narrow strand separating Card's Pond from Block Island Sound. Five homes were built along this section of the barrier beach in the early 1930's. At that time, the homes were situated near the back property lines. Aerial photographs indicate the primary dune system was well established and densely vegetated. After sixty years of shoreline retreat, most of which has taken place in the last seventeen years, the primary dune …

Littoral And Limnetic Zooplankton Communities In Lake Mead, Nevada-Arizona, Usa, Patrick J. Sollberger, Larry J. Paulson
Publications (WR)
Zooplankton were collected from adjacent littoral and limnetic sites in Lake Mead, Nevada-Arizona, USA. Limnetic species dominated both littoral and limnetic zooplankton communities; littoral species rarely exceeded 2% of monthly total zooplankton densities. Low species richness of littoral taxa and high similarity in species composition between littoral and limnetic habitats appeared to result from uniform horizontal physical and chemical environments, due to horizontal mixing, and from the absence aquatic macrophytes. Significant differences in spatial distribution occurred in phytoplankton biomass, total zooplankton density, and fish "abundances; highest concentrations of these factors occurred nearest an inflow high in nutrients and progressively declined …

The Lake Mead Fertilization Project is a research program designed to investigate the potential for using large-scale artificial fertilization to enhance the game fisheries of this reservoir through an increase in the population of threadfin shad, the system's primary forage species. A substantial decline in the population of largemouth bass, together with poor condition of adult striped bass, are the two major issues affecting the Lake Mead game fisheries. Both issues have been hypothesized to be a result of an inadequate amount of forage in the reservoir. Previous studies have in turn suggested that a major factor limiting the shad …
