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.

Laser Levelling Land For Flood Irrigation, M D. Green, J. P. Middlemas
Laser Levelling Land For Flood Irrigation, M D. Green, J. P. Middlemas
Journal of the Department of Agriculture, Western Australia, Series 4
Since the introduction of laser levelling to Western Australia's South-West irrigation area five years ago, many farmers have benefited from this new and precise method of land-forming.
The use of lasser controlled earthmoving equipment to redevelop irrigated paddocks has led to improved irrigation efficiency and drainage. Less water is used for each irrigation, water is applied more evenly and less labour is needed. many older, grass-dominated paddocks have been reseeded to improve pasture species.
Water Quality For Irrigation, P R. George
Water Quality For Irrigation, P R. George
Journal of the Department of Agriculture, Western Australia, Series 4
Although irrigation and salinity problems are frequently inseperable, there is a range of management methods that can be used to handle marginal quality water. Freuently these methods are simple, but require careful planning.
The wide range in tolerance of crops to salinity can be exploiter to ensure that appropriate crops are selected for the water available.
Because crops vary in their sensitivity to salt uptake in the leaves or the roots, watering methods can be changed to avoid problems. For profitable production enough water should be applied to ensure adequate water is available for plant growth as well as to …
Salinity Control In Northern China, G A. Robertson
Salinity Control In Northern China, G A. Robertson
Journal of the Department of Agriculture, Western Australia, Series 4
China has vast areas of saline land, perhaps as much as six million hectares. Some of this saline land is a result of marine influence in coastal areas and some is the resultof soil formation in areas with saline geological deposits and inadequate rainfall to leach out the salts at that time.
However, most saline soils in China are as a result of secondary salinisation processess induced by a hydrological imbalance resulting from over-clearing of the land or irrigation. This imbalance has produced rising watertables bringing the salt closer to the soil surface.
In this article, G..A. Robertson, Commissioner …

Water Supplies : Dams And Roaded Catchments, W J. Burdass, T. R. Negus, A. L. Prout, I. A. F. Laing
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australia's Upper and Lower Great Southern statistical areas include most of the broad-scale agricultural land south of a line from Perth to Hyden. Much of the area is well-developed and carries 13.4 million sheep, 203 00 cattle and 95 000 pigs, almost half the State's livestock.
There are few natural rivers and lakes to water livestock in summer and much of the bore water is salty. On-farm waterr conservation, therefore, consits mainly of excavated earth tanks (dams) which are filled by surface runoff or shallow seepage. In the drier areas and in the sandplain roaded catchments have neen built …
Dam Site Selection In The North-Eastern Wheatbelt, J L. Frith
Dam Site Selection In The North-Eastern Wheatbelt, J L. Frith
Journal of the Department of Agriculture, Western Australia, Series 4
Western Australia's wheatbelt farm dams are dug three to eight metres deep and are generally sited in soils which either are inherently impermeable or can be made so during construction.
In the eastern and north-eastern wheatbelt, however, only a small proportion of the soils meets these criteria. Dam site selection in these areas therefore depends on a good knowledge ofwhich soils aresuitable and on our being able to locate them efficiently by using surface indications such as surface soil, natural vegetation or topographic features.
Improved Catchments For Farm Dams, I A F Laing
Improved Catchments For Farm Dams, I A F Laing
Journal of the Department of Agriculture, Western Australia, Series 4
The amounts and frequency of runoff from unimproved farmland catchments in Western Australia's cereal and sheep districts are notoriously variable and unreliable. As a result many farmers have constructed improved catchments to ensure better reliability of farm dams for livestock and homestead water supplies.
Improved catchments which are used extensively on these farms are all of the compacted or bare-earth type. These include roaded catchments, flat batter dams and, to a lesser extent, scraped catchments. This article mainly discusses roaded catchments, the most common of the improved catchment types on farms.
Sandplain Hardpan : A Different Dam Construction Material, A F. Mccrea
Sandplain Hardpan : A Different Dam Construction Material, A F. Mccrea
Journal of the Department of Agriculture, Western Australia, Series 4
Before 1980, the Department of Agriculture did not believe that suitable farm dam materials could be found in light land soils. However Beacon earthmoving contractor, V> J> Pavlinovich, has demonstrated that where suitable cemented subsoils or 'hardpan' existed, a succcessful dam site could be found.
This material should not be confused with compaction or traffic hardpans ehich are dense layers of soil found near the surface. Traffic hardpans result from compaction of soil materials with the passage of vehicles and farm machinery. Rather, the hardpan referred to here is a natural subsoil layer that has been cemented by silica and …

Chemical Sealing Of Earth Dams, R G. Pepper
Chemical Sealing Of Earth Dams, R G. Pepper
Journal of the Department of Agriculture, Western Australia, Series 4
Leakage is not a major cause of failure of farm dams in the Western Australian wheatbelt, but it is a problem in some districts where it can limit stock carrying capacity. Leaking dams are especially common in the West midlands, the north-eastern wheatbelt and the 'jarrah-belt' which extends from Bindoon, southward to Manjimup and Mt Barker (see map and Table 1).
Some dams which leaked when first built have sealed themselves over the years. Others have been successfully sealed using sodium tripolyphosphate.

Delineation Of Landslide, Flash Flood, And Debris Flow Hazards In Utah, David S. Bowles
Reports
During 1982, 1983, and 1984, abnormally wet conditions in Utah triggered flash floods, landslides, and debris flows. Pore pressures built in hillside soils below melting snows and during prolonged periods of rainfall until the mass suddenly gave way, sometimes as a landslide and other times as a non-Newtonian debris flow that moved rapidly long distances down mountain slopes until finally stiffened by moisture loss or velocity loss because of flatter gradients. Also, runoff from heavy rainfall bursts picked up weathered and other loose material that accumulated on land surfaces over long dry periods . The sediment laden waters flowed out …

The most desireable types of learning involve direct, first hand experience, not just a teacher's interpretation of these experiences. This set of learning experiences has been designed for teachers, teachers-in-training, and children, Each concept includes background information for the teacher and learning activities for the children. Lessons are designed so taht a teacher can successfully teach a unit or lession with a minimum of knowledge, preparation, and equipmnet. Most of the suggested …
A Methodology For Estimating Instream Flow Values For Recreation, Parvaneh Amirfathi, Rangesan Narayanan, A. Bruce Bishop, Dean Larson
A Methodology For Estimating Instream Flow Values For Recreation, Parvaneh Amirfathi, Rangesan Narayanan, A. Bruce Bishop, Dean Larson
Reports
Water flowing in streams has value for various types of recreationists and is essential for fish and wildlife. Since water demdns for offstream uses in the arid west have been steadily increasing, increasing instream flows to enhance the recreational experience might be in conflict with established withdrawals for uses such as agriculture, industries, and households. Since market prices are not observable for instream flows, the estimation of economic value of instream flow would present well known difficulties. The household production function theory was used to build the theoretical model to measure economic value of instream flow. A representative sample of …

Preliminary Identification, Analysis, And Classification Of Odor-Causing Mechanisms Influenced By Decreasing Salinity Of The Great Salt Lake, C. Earl Israelsen, Darwin L. Sorensen, Alberta J. Seierstad, Charlotte Brennard
Reports
Introduction: The rising level of the Great Salt Lake has received a great deal of attention because of the resulting physical damage to adjoining properties, threatened distruption of major transportation facilities, and environmental damage to feeding and resting areas for migratory waterfowl. Another problem of growing concern is that some zones of the lake are producing odors that are objectionable to nearby populated areas. These odors are most offensive during the warm summer months and appear to be increasing with the rising levels and decreasing salinity of the lake water. This report presents the approach taken and the findings of …
Problems Of Small Privately Operated Water Companies In Utah, Jay M. Bagley, Frank W. Haws
Problems Of Small Privately Operated Water Companies In Utah, Jay M. Bagley, Frank W. Haws
Reports
Although one in seven domestic water supply systems in Utah are privately owned and operated, they are characteristically small with 94 percent serving populations of less than 1,000. Per capita costs of service vary greatly but become relatively high for locations that are remote, where terrain and climate are extreme, where scale economies are absent, and where materials and skills for system repair and replacement are not locally available. Statistics indicate that the incidence of water quality violations relate strongly to system size. Yet corrections are often more difficult to achieve because well trained and full time operators cannot be …

Identification And Modeling The Impact Of Marine Shale Bedrock On Groundwater And Stream Salinity: Upper Colorado River Basin, Christopher J. Duffy, Jerome J. Jurinak, Sanjay Sangani, Ali Azimi
Reports
Recent studies have shown that groundwater is a major contributor to stream salinity in the Upper Colorado River Basin. The primary salt sources are the marine shales and shale residuum that underlie the soils of much of the basin. A field site in the Price River Basin, a tributary to the Green and Colorado Rivers, was selected to study the physical and chemical factors that control the interactions between groundwater and these shales. Preliminary data were available at the site as a result of a Bureau of Reclamation study conducted by CH2M Hill. On the basis of the CH2M Hill …
