Western Water Law in Transition (Summer Conference, June 3-5)

Conference organizers and/or faculty included University of Colorado School of Law professors James N. Corbridge, Jr., Lawrence J. MacDonnell, Richard B. Collins, David H. Getches and Charles F. Wilkinson.

The prior appropriation doctrine has governed the allocation and use of water in the western United States since the 1850s. The shifting nature of water demand is bringing about changes in the traditional legal system. This conference will consider the fundamental principles of the prior appropriation doctrine together with the important new developments in the law now underway throughout the West.

Drought Proofing The Farm : Case Studies, J L. Frith

Journal of the Department of Agriculture, Western Australia, Series 4

For many years, Western Australia's north-eastern wheatbelthas suffered chronic shortages of water for stock and domestic use. The area's averageannual rainfall is generally low - less than 300 millimetres - and droughts in the 1970s caused futher problems. manydams in the area leak or have inadequate catchmentsand groundwater is scarce ormofmpoor quality.

In March 982, the Western Australian Government provided $100 000 for the Department of agriculture to demonstrate the potential of establishing permanent, drought-proof water supplies on farms in the north-eastern wheatbelt. The methods were to use exixting techniques to build dams and catchments. In a year of low …

Water Conservation Information Dissemination During The 1997 Drought Emergency, L. Douglas James, Wade H. Andrews

Reports

As drought conditions in 1976 and 1977 became increasingly severe throughout the west and affected many other parts of the country, many states began special drought information dissemination efforts. This study was organized to provide for the exchange of information among the respective states a forum that could reduce duplication among independent efforts. The project collected information. on: A) Water-user conservation practices, 1) domestic use, a) inside use, b) outside use, 2) industrial, 3) commercial, and 4) irrigation; B) Water-supplier management practices, 1) water conservation Inducements, 2) emergency supply augmentation, a) groundwater mining, b) water harvesting, c) water reuse, 8) …

Native Plants : Water Savers In The Garden, K S. Cole

Journal of the Department of Agriculture, Western Australia, Series 4

The climate of Western Australia may be one of the best in the world for people but it is a difficult one for many of our imported, and common garden plants. as a consequence, some 70 per cent of our summer water usage is for gardens and lawns.

This is not the sort of statistic that we should accept easily or happily.

There is a solution to this problem: a new approach to home gardening is required.

The new garden is based on W. A.'s own colourful native plants, which are adapted to mild winters, hot dey summers and poor …

Water Economy For Lawns And Gardens, K S. Cole

Journal of the Department of Agriculture, Western Australia, Series 4

Much of the summer water consumption occurs because it is widely believed that heavy summer watering is necessary. Householders often mistakenly water heavily to keep their gardens green and growing. Many may not realise that gardens can be kept vigorous and healthy with much less water than is commonly applied.

Micronutrients And Biological Patterns In Lake Mead, Hasan K. Qashu, Lorne G. Everett, J. S. Carlson, Bureau Of Reclamation

Publications (WR)

Progressive increases in concentration of dissolved solids in the Colorado River water from Lake Powell to Imperial Dam seem to alter plankton dynamics and biological productivity of the river. Also, changes in biological productivity and micronutrients concentrations occur within the same reservoir. Development of a digital simulation model to predict micronutrients concentrations and biological productivity is necessary for diagnosing changes in plankton population and effluent-carrying capacity of the system.

The objectives of the study are: (1) to determine trace metal balance at different locations in Lake Mead, (2) to measure biological productivity and conduct plankton population counts at each sampling …

Water Conservation : The Storage Life Of Farm Dams, D J. Carder

Journal of the Department of Agriculture, Western Australia, Series 4

HOW MANY stock can a dam of a certain size and depth be expected to carry and how long will the supply last?

What size of dam is needed in case the winter rains fail? How many stock can a dam support and still provide a drought supply?

Available Water Supply Of The Las Vegas Ground-Water Basin Nevada, Glenn Thomas Malmberg

Publications (WR)

The Las Vegas ground-water basin as described in this report includes the southern part of Indian Spring Valley, Three Lakes Valley, the northern half of Ivanpah Valley, and Las Vegas Valley. These valleys in part are inferred to form a hydrologic unit that includes an area of about 3,000 square miles in the southern part of Clark County, Nev.

The valleys forming the Las Vegas ground-water basin are broad structural depressions surrounded by mountains. The climate of the region is arid, and precipitation in the basin lowlands rarely exceeds 5 inches per year. Drainage is interior except for occasional Hood …

Water Conservation On The Farm, John W. Lewis

Journal of the Department of Agriculture, Western Australia, Series 4

SMALL scale conservation of water for agricultural use is becoming increasingly important throughout Australia.

As land development intensifies, it is natural that farmers turn to more dams and earthen tanks for stock water and irrigation.

Adequate water is essential to supply the carrying capacities made possible by improved pastures, and where greater quantities of water can be stored, fodder crops, pastures, orchards and vegetables can be irrigated.

Dams On The Hillsides

Journal of the Department of Agriculture, Western Australia, Series 3

A reader of the "Journal of Agriculture" recently wrote to the Commissioner of Soil Conservation concerning the current tendency towards sinking dams on hillsides. He stated that many farmers and contractors were throwing up holding banks in such a manner that a large percentage of the water impounded was lost by seepage under the banks.

Progress Report On The Ground-Water Resources Of The Las Vegas Artesian Basin, Nevada, George B. Maxey, C. Harry Jameson

Publications (WR)

Whether the tremendously increased population acquired by Las Vegas in the years 1940 to 1942 will be retained cannot at present be foretold. However, the valley will undoubtedly be expected to support a considerably larger population than it did at any time prior to 1940, and continually increasing demands on the water supply for innumerable pcacetimc activities must be anticipated. Therefore, a sound evaluation of tho ground water resources of Las Vegas Valley is directly in line with the other wisely progressive planning programs which are now operating or are taking shape in the valley as well as in the …
