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 …
A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon
A Report On The Condition Of The Gascoyne Catchment, D G. Wilcox, E A. Mckinnon
Resource management technical reports
Severe flooding in Carnarvon followed heavy rains on the Gascoyne Catchment in February 1961. The flooding and erosion were extensive enough to suggest that run-off from the catchment was excessive. Lightfoot (1961)* reported that excess run-off was due to degradation of the catchment area. This report will describe the catchment area in terms of the degradation of its rangeland and its susceptibility to erosion.

Adsorption Of Sulfur Dioxide On Douglas Fir Woodchips, Uen-Ping David Wang
Adsorption Of Sulfur Dioxide On Douglas Fir Woodchips, Uen-Ping David Wang
Dissertations and Theses
In recent years, people have raised their alertness to the hazard of air pollution. Sulfur dioxide is one of the most dangerous chemical compounds among those air pollutants. A study on removing sulfur dioxide from an air stream by adsorption using wood chips as the adsorbent is presented in this thesis.
The reason for using wood as an adsorbent is that wood is a porous material and possesses a large surface of cell cavities which can hold a great amount of moisture. As sulfur dioxide gas is passed through the wood bed, it would be either condensed in the cell …

Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr
Fisheries Research Reports
Millstream has long been recognised as an unique and outstanding area, both scenically and from a biological aspect. The area of prime interest consists of a series of deep pools in the bed of the Fortescue River (about 15 miles long including Gregory Gorge) and the springs and streams which feed them. Most of the springs are in the sides of the river bed but one of the largest is about 1% miles to the south. This feeds a swift flowing stream running north into the river bed.
The first Europeans to see the area were the exploring party led …

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 …

This study developed from observations made during an earlier study on Lake Mead which was reported in CHE-70, Water Quality Study of Lake Mead. Results from that study indicated that poor-quality water was flowing into the Las Vegas Bay reach of Boulder Basin, Lake Mead. Also reports of deteriorating water quality, resulting in taste and odors in domestic water supplies taken from Boulder Basin as well as a reduction in the attractiveness of Las Vegas Bay for recreational uses caused by aquatic plants and algae blooms, indicated a need for a concentrated study concerning the effects of flows from Las …

Thermal Requirements To Protect Aquatic Life, Clarence M. Tarzwell
Thermal Requirements To Protect Aquatic Life, Clarence M. Tarzwell
United States Environmental Protection Agency: Publications
Water temperatures affect aquatic organisms in a number of ways, both directly and indirectly. Some of the latter effects are quite subtle. High temperatures can have direct lethal effects but sublethal levels operating over long periods can be just as harmful through delayed lethal effects and the production of nonlethal stresses which eventually result in changes in the population, reduced growth or reproduction, and the lowering of resistance to parasites, dis ease, and competitors. Temperature, in combination with certain other factors such as day length, influences re producing processes. High water temperatures may stimulate or retard migration, spawning, feeding, and …

Bulletins - 3000 - 3999
MUCH recent discussion on conservation has centred around the importance of wild flower reserves and the need for protecting one of thci State's most important tourist attractions. Although less important to visitors than the flowers, many of our wild animals hold equal interest for nature lovers and scientists, and they also need protection.
ALTHOUGH the brilliance and diversity of West Australian wildflowers are widely appreciated, the localities where they can best be observed in their natural state are not so well known.
In this article a brief outline is given of the more important districts in the south western part …

Journal of the Department of Agriculture, Western Australia, Series 4
IN AUSTRALIA the seasons of summer, autumn, winter and spring do not have the importance that they have in the Old World, and though summer and winter weather are quite different, there is not the obvious difference in autumn and spring conditions that there is in the colder countries.
This is largely due to the difference in vegetation and in its life cycle in the different places.

Likelihood Of Drought Years In South-Western Australia : How Often Can Droughts Such As That Of 1969 Be Expected In Western Australia's Farming Areas?, Eugene Adsil Fitzpatrick
Journal of the Department of Agriculture, Western Australia, Series 4
Because of the serious consequences of drought to individual farmers and to Western Australia's economy, it is worth making an early appraisal of the 1969 rainfall conditions that led to the State's most recent drought in an attempt to estimate how often such seasons might be expected in the agricultural areas.
Dry Season In The Eastern And North-Eastern Wheatbelt, George Henry Burvill
Dry Season In The Eastern And North-Eastern Wheatbelt, George Henry Burvill
Journal of the Department of Agriculture, Western Australia, Series 4
The drought of 1969 ended an 11-year run of good seasons in the eastern and north-eastern wheatbelt. Good years usually have above average rainfall; wheat yields and pasture growth are greatly reduced if rains are well below average. Eighty years records show that half the years must be expected to be below average and about one-third could be well below. This area produces one-third of the State's wheat and has 9 per cent, of its sheep.

Trace Metal Analysis Of Barren River And Nolin River Reservoirs By Atomic Absorption Spectroscopy, Mary Jo Kennedy
Masters Theses & Specialist Projects
This research was part of a project underway at Barren River and Nolin River Reservoirs in south-central Kentucky. The research was partially supported by a grant through the Sport Fishing Institute, Washington, D.C.
The study reported herein was concerned with the analysis of trace metal concentrations in the two reservoirs. It is believed that the fish population may in part depend upon the trace metals present in the water. It is anticipated that the data presented in this paper will eventually be correlated with the biology studies of the reservoirs being carried out by the Department of Biology of Western …

History Of The State Vermin Barrier Fences, Formerly Known As Rabbit Proof Fences, J S. Crawford
Research Reports
There is evidence of rabbits arriving in Australia as far back as 1788, and it is well known that others were liberated on islands around the coast, including some off the coast of Western Australia. However, they remained localised and it is now generally accepted that the rabbits which did spread originated from a small shipment of the wild type brought on the Clipper “Lightning” in 1859. They were released on “Barwon Park”, the property of Thomas Austin, near Geelong in Victoria, and within three years, had reached pest proportions

Bulletin No 3609 - Land Development In The South Eastern Wheatbelt, G T. Halpin, P. Nelson
Bulletins - 3000 - 3999
Interest in the development of light lands in the south-eastern wheatbelt was spurred by the many ex-servicemen seeking farms after the 1939-45 World War.
Previous attempts to develop this area had been frustrated by poor crop yields, and by the poor carrying capacity of those volunteer pastures which developed on cleared land.
Research into reasons for the poor crop results was begun in 1948-49 with trials sown by Messrs Smith and Halpin between Borden and Lake Grace. The results clearly showed the important role played by copper and zinc in successful crop growth. Since then, field trials have been conducted …
