Water Requirements For Waterfowl Areas Near The Great Salt Lake Parts V-Vi, J. E. Christainsen, Ming Chang Tsai, D. K. Kaushik, J. B. Law, J. W. Teeter Nov 1961

Water Requirements For Waterfowl Areas Near The Great Salt Lake Parts V-Vi, J. E. Christainsen, Ming Chang Tsai, D. K. Kaushik, J. B. Law, J. W. Teeter

Reports

This report reviews activities on this project since the Progress Report, Part IV, June 1961.

The summer of 1961 has been one of the driest on record for Ogden Bay and Howard Slough Refuge. The extreme shortage of irrigation water has resulted in very little flow in the Howard Slough which originates from return flow. The available water from the Weber River for the Ogden Bay Refuge was also the lowest on record. The scarcity of water at these two refuges has resulted in increased salinity.

Most of the routine work on the project during the summer was done by …


Silt Project, Colorado: Colorado River Storage Project, U.S. Department Of Agriculture Aug 1961

Silt Project, Colorado: Colorado River Storage Project, U.S. Department Of Agriculture

Elusive Documents

The purpose of this report is to present information regarding the soil capabilities for irrigation, the present and future land use and production pattern, the costs associated with on-farm irrigation development, prospective size and type of farm, direct agricultural benefits and probable farm incomes with proposed irrigation development for the Silt project. In addition to the agricultural phases, this report deals with the impacts of the project on the national forests and the relationship of watershed conditions to the project.

This report also is intended to aid the Bureau of Reclamation in developing their Definite Plan Report, and to provide …


Water For Man, Sterling A. Taylor Jan 1961

Water For Man, Sterling A. Taylor

Faculty Honor Lectures

Man's uses for water are rapidly increasing. His demands and needs for water for his personal use and for cleanliness, recreation, industry, and food production are increasing as the population and standard of living rise. At the same time, his knowledge of the behavior and nature of water is increasing.


Water Conservation On The Farm, John W. Lewis Jan 1961

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.


Is Your Water Supply Safe?, D C. Mickle Jan 1961

Is Your Water Supply Safe?, D C. Mickle

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

THERE can be no doubt in anyone's mind that the need for a clean, safe and adequate water supply is essential for the production of high quality milk and cream.

It naturally follows, that, even though every possible care has been taken in an endeavour to produce clean, germ-free milk and cream, contamination by bad water can render these efforts void.


Potatoes Sprinkler Irrigated From The Collie River, John W. Lewis Jan 1961

Potatoes Sprinkler Irrigated From The Collie River, John W. Lewis

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

THE highly productive soils of the flats along the Collie River at Roelands are an important source of many of our summer grown potatoes in this State.

Large areas are planted year after year, the record being held by Mr. Clarry Cox of Roelands, who has planted potatoes on the same seven acres every season since 1922.


Automatic Waterers For Day Old Chickens, P Smetana, W. Ward Jan 1961

Automatic Waterers For Day Old Chickens, P Smetana, W. Ward

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

ONE of the most tedious and time consuming tasks on a poultry farm is the provision of water to chicks from day old up to the age of three or four weeks.

Most poultry farmers use half-gallon glass fonts with metal bases for the first few weeks, until the chicks are old enough to use the automatic watering system usually situated along one wall of the brooder house.

This cumbersome glass font system can be replaced by the cheap and easily installed automatic watering system described below. This system has already been adopted by several local poultry farmers.

Thirsty Cows Are Poor Milkers, S R. Dunstan Jan 1961

Thirsty Cows Are Poor Milkers, S R. Dunstan

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

THE HOT summer weather is not far away, and now is a good time for the whole milk producer to attend to those points which will ensure that milk production is maintained at a high level during this period.


A Rational Approach To The Estimation Of Evaporation And Evapotranspiration From Climatological Data, Jerald Emmet Christiansen, B. B. Patil Jan 1961

A Rational Approach To The Estimation Of Evaporation And Evapotranspiration From Climatological Data, Jerald Emmet Christiansen, B. B. Patil

Reports

Many attempts have been made to derive mathematical expressions relating evaporation and evapotranspiration, or consumptive use, to climatological data. IN the United States, the Blaney-Criddle formula is probably the best known for estimating consumptive use (2 and 3). Blaney (1) has also suggested that this formula is suitable for estimating evaporation as measured with a Weather Bureau pan. Other well known formulas are the Penman formulas (10), the Thornthwaite formula (15) and the Hargreaves formulas (8). Halkias, Beihmeyer and Hendrickson (6) suggest that water requirements of crops can be determined from atmometer data. Lowry and Johnson (() in an early …


Model Analysis Of Spillway And Stilling Basin Of Porcupine Dam, Gordon H. Flammer, C. Earl Israelsen Jan 1961

Model Analysis Of Spillway And Stilling Basin Of Porcupine Dam, Gordon H. Flammer, C. Earl Israelsen

Reports

Introduction: The Engineering Experiment Station at Utah State University was engaged by the Utah Water and Power Board to make a model analysis of the spillway and stilling basin of the Porcupine Dam. This dam will be located on the East Fork of Litle Bear River, just east of Avon, Utah. It will be approximately 650 feet long and 160 feet high, composed of zones earth fill with rock rip-rap facing. The spillway will have a reinforced concrete inlet section and the remainder of the chute and stilling basin will be excavated out of the rock and leck unlined. The …


Manage Your Rainfall For Maximum Production, J E. Watson Jan 1961

Manage Your Rainfall For Maximum Production, J E. Watson

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

TTOW much would an extra inch of rainfall be worth to you? Much sloping land loses this much and more by run-off every year.

The soil is the main asset of your farm, but your profits depend on how you manage the rain which falls on it.
