A Study Of Primary Productivity In A Nebraska Interstate 80 Lake, Gilbert Adrian, Carl Throckmorton, Bob Mcdonald
A Study Of Primary Productivity In A Nebraska Interstate 80 Lake, Gilbert Adrian, Carl Throckmorton, Bob Mcdonald
Nebraska Game and Parks Commission: Staff Research Publications
The primary productivity of a small gravel pit lake in the Platte River Valley of Nebraska was studied for a 2-year period. Daily production rates were estimated from near weekly samples, with calculations done by computer. Emphasis was placed on production under ice during winter conditions. Annual production was estimated and is compared with several other lakes in North America.
Grain Sorghum In The Ord Valley : Three Crops A Year?, P J. May
Grain Sorghum In The Ord Valley : Three Crops A Year?, P J. May
Journal of the Department of Agriculture, Western Australia, Series 4
High temperatures and ample irrigation water allow grain sorghum to be grown throughout the year on the Ord River Irrigation Area, and observations in 1969-70 indicated that it may be possible in this area to produce three crops in one year from one planting, by ratoon cropping.
This article describes the technique and discusses its possibilities on the Ord.
The sorghum midge, one of the worst pests of sorghum, could well make ratoon cropping impossible, but the midge has not yet been seen in this area.
Fisheries Report No Vii (7) - Results Of A Biological Survey Of The Millstream Area, A. A. Burbidge Dr
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 …

Growing Plants With Salty Water, C V. Malcolm, S. T. Smith
Growing Plants With Salty Water, C V. Malcolm, S. T. Smith
Journal of the Department of Agriculture, Western Australia, Series 4
LACK of good quality water in many parts of Western Australia often forces people to use salty water for irrigation and gardening.
This article gives some hints on how to reduce salt damage to plants when salty water must be used for irrigation or gardening.
It includes a table of plants which may be irrigated with water of varying degrees of salinity and lists precautions which should be taken for each group.
New Varieties Could Extend The Peach Canning Season, S R J Newton
New Varieties Could Extend The Peach Canning Season, S R J Newton
Journal of the Department of Agriculture, Western Australia, Series 4
THE peach canning industry in Western Australia at present has only a limited period of operation, coinciding with the harvest time of the major variety, Golden Queen.
New canning peach varieties tested at Stoneville Research Station could be used to extend the harvest period of canning peaches beyond that of the present standard variety, Golden Queen.
This would have obvious advantages for growers and a canning industry.
The South African variety Keimoes was the most promising canning peach tested. Tests on other varieties are continuing.

Development Of A Procedure For Determining Spacial And Time Variations Of Precipitation In Venezuela, Luis E. Ramirez
Development Of A Procedure For Determining Spacial And Time Variations Of Precipitation In Venezuela, Luis E. Ramirez
Reports
An analysis of the influence of the length of the record in the reliability of mean values of precipitation was made for the Caracus-Cagigal Station in Venezuela. Ten series of values were obtained for 10, 15, 20, 25, 30, and 35-year periods, extracted for sliding intervals for the overall record of 75 years. The reliability of mean values computer from Figure 3 was quite low for 10, 15, and 20- year periods. The long term record means had higher reliability, increasing with the number of years in the records, but the differences are not important in terms of accuracy. Precipitation …

This is a report of the world accomplished and results obtained under a 2-year contract. The primary objective of the Wasatch Weather Modification Project is to assess the effectiveness of selected procedures for increasing the water supply in the Wasatch Mountains by cloud seeding. As part of this overall objective, an airborne seeding experiment has been conducted for two winter seasons. Preliminary results of this experiment indicate a positive seeding effect within and on the periphery of the designated target area. A summary of project designs, procedures, and problems encountered is also included. Data processing, editing, analysis and display procedures, …

The Effect Of Las Vegas Wash Effluent Upon The Water Quality In Lake Mead, D. A. Hoffman, P. R. Tramutt, F. C. Heller, Bureau Of Reclamation
Publications (WR)
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 …

Range Evaluation Using Aerial Photography, D G. Wilcox
Journal of the Department of Agriculture, Western Australia, Series 4
The Department of Agriculture, in association with the University of Western Australia, recently undertook a study of the application of aerial photography to range condition monitoring in three rangeland types in the mulga zone of Western Australia.
The project was financed by the Rural Credits Development Fund and the C.S.l.R.O. Rangelands Research Unit.
This article deals in a general way with the possible use of aerial photography in rangeland administration.

The Fishes Of The Nemaha Basin, Nebraska, Larry Witt
Nebraska Game and Parks Commission: Staff Research Publications
The possible effects of proposed watershed management practices on fish resources of the Nemaha Basin were poorly understood; thus, a study was undertaken to ascertain the species of fish present and their relative abundance and distribution within the basin. Thirty-five species were collected, 34 of them from the Big Nemaha River system and 28 from the Little Nemaha River system. These data may be used as a basis for future studies of fish population changes in the Nemaha Basin and possibly as a basis for studies in other watersheds.

United States Environmental Protection Agency: Publications
Hazards to marine and estuarine fauna associated with offshore drilling of oil and with transport of large quantities of oils via tankers are numerous and understandable. At present, there is a growing body of evidence on adverse effects to these organisms of crude oil (1) (2) (3) (4) (5) (6) (7) (8) (9) and chemical oil counteracting agents or dispersants (5) (6) (9) (10) (11) (12) (13) (14) (15) (16) (17). These effects are well summarized by Smith (18) and by Carthy and Arthur (19).
Comparatively few workers have studied the influence of oil-dispersant mixtures of marine life. Studies by …
