Fisheries Report No 13 - Results Of A Biological Survey Of The Shire Of Kent, Western Australia, N. L. Mckenzie

Fisheries Research Reports

The Department of Fisheries and Fauna is responsible for the conservation of the native fauna in Western Australia. The main approach to this problem has been the creation of reserves for "The Conservation of Flora and Fauna". These reserves, known as "Wildlife Sanctuaries", are controlled by the Western Australian Wild Life Authority - a Statutory Authority serviced by the Department.

The object of the acquisition programme is to develop a reserve system which will include, as far as possible, a full and permanent cross-section of the State's native floral and faunal assemblages and, at the same time, provide for the …

Bulletin No 3867 - Water For Agriculture. Clearing Cloudy Or Coloured Water, N. E. Platell

Bulletins - 3000 - 3999

THE suspended material in most water supplies is generally clay, although sometimes organic matter and materials precipitated from solution, such as hydrated iron oxides, may be present. Coloured waters are those waters that are still coloured, due to dissolved coloured matter, after suspended material has been removed. Some coloured waters such as those found in swampy areas may be entirely free of suspended material.

The amount of clay or colour present is mainly of concern where the water is used for household purposes. Only rarely is the clay or colour present in such quantities that the water is undrinkable for …

Saltmarsh Ecology And Resource Protection, Gerard Desire Blais Jr.

Marine Affairs Theses and Major Papers

A panoramic lack of conservation education has produced a populace largely unaware of the value of marshland resources or measures for their protection. In a relentless era of ecological abuse, wetlands and salt marshes rank with endangered animal species in the quantitative loss culminating in extinction. Challenged continually by the relentless sea and exploited by unsound attempts at development, management, or even conservation, the efficiency of the marshlands is decreasing with each successive invasion. There is a demonstrated reduction in biological productivity, flood control, and water quality in areas where dredging, draining, and filling of marshes has taken place.

Bulletin No 3861 - Kimberley Research Station - Progress Report 1972, J. R. Mcalpine, R. H. Gunn, P. Jakobsen, R. Wetselaar, J. J. Basinski, N. J. Thomson, A. G. L. Wilson, D. H. Mackenzie, A. J. Millington, D. F. Beech, P. C. Owen, B. G. Williams, C. G. Blunt, A. Mcr Holm

Bulletins - 3000 - 3999

The systematic investigations of the potential of the Ord area for irrigated farming began during the Second World War when the possibilities of damming the river were first examined, initial soil survey was carried out, and agricultural experiments started. The Kimberley Research Station was established on its present site in 1945. A year later the State and Commonwealth Governments agreed to finance and operate the Station jointly, with CSIRO and the Western Australian Department of Agriculture being responsible for research.

The construction of the main dam designed to store 5,675 million m" ( 4.6 million acre feet) was completed in …

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 …

The 1963-64 Lake Mead Survey, J. M. Lara, J. I. Sanders, Bureau Of Reclamation

Publications (WR)

The 1963-64 Lake Mead survey was run to compute the reservoir capacity. Results of the geodetic and hydrographic surveys and sediment sampling equipment are described. The geodetic survey showed Hoover Dam subsided an average of 118 mm since 1935. Sonic sounding, photogrammetry, and crosssectional profiling methods were used to run the hydrographic survey. Reservoir area and capacity tables were generated using an electronic computer. The present lake capacity is 29,755,000 acre-ft and the reservoir surface area is 162,700 acres at elevation 1229 ft. 2,720,000 acre-ft of sediments accumulated in the lake since 1935. A unit weight of 60 Ib/cu ft …

Soil Conservation Handbook, D J. Carder, G W. Spencer, Soil Consevation Service

Books & book chapters

Soil Conservation means, basically sound land management. With good management the Ste's resources of productive land can be bot only maintained but actually improved. It is a question of deciding the best use for each soil type and situation. Profitable Production must be kept up in changing economic conditions without destroying land assets in the process.

West Midlands Development : Soil Map Used To Group Similar Soils Into Land Use Classes, Department Of Agriculture, Western Australia

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

Selection of areas for initial treatment is basic to economic development of blocks in the West Midlands.

Obviously, it is best to develop large areas of the most productive "land use classes" first in order to obtain the highest and earliest returns on capital.

West Midlands Development : Erosion Prevention And Control, G W. Spencer

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

THE prevention of soil erosion is essentially a matter of using each soil according to its potential, and treating it according to its needs.

Good land use and sound management practices are the best preventive measures.

The Ord River Catchment Regeneration Project. 1. The Nature, Extent And Causes Of Erosion In The Ord River Catchment Area, K Fitzgerald

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

OF the 17,800 square miles of Ord River catchment area, an estimated 1,450 square miles of country is subject to varying degrees of erosion.

This lies astride the Ord River and its major tributaries, the Elvire, Negri, Stirling, Panton, Turner, Nicholson and RB rivers.

The bulk of the eroded country lies in W.A. but part projects into the Northern Territory.

Water Chemistry Survey Of Boulder Basin, Lake Mead, P. R. Tramutt, Bureau Of Reclamation

Publications (WR)

The survey results indicate that the impoundment of water behind Hoover Dam has not adversely affected the dissolved oxygen (DO) content and that water quality and DO content were uniform regardless of depth. The study made in April-May 1964 will provide water quality data of Lake Mead prior to releases from Lake Powell as a basis for evaluating Lake Powell's effect on water quality and limnology of Lake Mead. The performance of a DO analyzer was tested and found unsatisfactory at depths below 150 ft. Parameters tested by standard chemical analyses of water samples in the Denver Laboratory and by …

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 …

IN south-western Australia permanent rivers are virtually absent and the larger drainage systems such as the Swan-Avon, Murray and Blackwood, which have their headwaters in inland low rainfall areas, are generally saline.

The Gascoyne River Catchment Area, W M. Nunn

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

A RECENT Department of Agriculture survey of the Gascoyne River catchment area has indicated that deterioration of plant cover in the area contributes to the severity of floods which regularly damage the town of Carnarvon.

It is hoped that the results of the survey will help efforts to regenerate the catchment area, and reduce the risk of flooding.

Natural Paddocks Help Soil Conservation, G W. Spencer

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

ON most farms, particularly in the cereal and sheep districts, the paddocks as we know them are fenced off into neat squares or rectangles.

The original fencing was done in such a way that the paddock layout, as well as the fences, completely disregards the topography or natural features of the land. Often this has encouraged soil erosion.

In properly laid out paddocks there should be a very close relationship between the natural features of the farm, the fence plan, and soil conservation.

Fallowing And Soil Conservation, J E. Watson

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

Soil Conservationists don't always disapprove of fallowing, says Soil Conservation Service adviser J. E. Watson.

They are prepared to compromise, and accept fallowing as a useful practice where it means better pasture establishment or more effective land reclamation.

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 …
