Quality Farm Dugouts (3rd Edition) is a workbook developed by Water Specialists from across the Canadian prairies. It is designed to help you develop and maintain your dugout water system so that it meets your needs for years to come. The workbook provides a systems approach to improving both the supply and quality of water starting with the dugout watershed and continuing to its final use. The workbook contains 9 modules and 5 worksheets. It is recommended that you obtain a copy of the manual, which contains both completed examples of the worksheets as well as blank worksheets to use for your own farm dugouts.

This publication is a product of Alberta Agriculture and Forestry. The purpose of this manual is to provide the latest research information on improving both the quantity and quality of dugout water. It identifies and explains general dugout planning, design, construction, treatment, and management practices. It also indicates practices to avoid, and attempts to dispel a few myths about dugout water management.

How to Use this Manual

Quality Farm Dugouts contains nine modules including a number of worksheets that complement the text and add a very practical element to the manual’s use. A pocket in the front cover stores example worksheets. A pocket in the back cover stores blank worksheets and can be used to store other important documents for your dugout, such as completed estimates, record forms, and personal contacts. Although certain topics will be of more interest and value than others, we recommend that you start with Module 1 and work through the manual systematically.

Module 1 History - Provides background on the use of farm dugouts on the Canadian prairies.

Farm dugouts on the Canadian Prairies have been used as small, water storage reservoirs for many years. In areas where groundwater is either unavailable or of very poor quality, impounding surface runoff is often the only means of ensuring a continuous water supply. For the most part, dugouts capture the temporary surplus of surface water that occurs during snowmelt in the spring. Water may also be collected as runoff from summer rains, but it is typically of very low quality. In order to guarantee reliability of supply, storage capacity must be sufficient to compensate for years of insufficient runoff, summer losses due to evaporation, and winter losses due to ice formation....Read More

Module 2 Understanding Prairie Dugouts - Gives an understanding of some of the unique aspects of the prairie climate and the challenges involved in securing and maintaining a good supply of dugout water.

It is much easier to design, operate, and maintain high quality dugouts if you understand the natural processes that control them. This module explains some of these processes. Climate and landscape determine how much runoff will be captured by a dugout. Once the runoff is stored, the dugout provides an environment for a wide variety of plants, animals, and micro-organisms that can have a huge impact on water quality....Read More

Dugout Design: The construction and management of a dugout can have a large impact on water quality. Design options allow dugout owners to control inflow and permit only the highest quality water to be stored. Once runoff has been collected, good management can prevent water quality from deteriorating as illustrated in Figure 4-1 Dugout Design and Beneficial Management Practices....Read More

Module 5: Operating Systems - Discusses water intakes, pumps, piping, aeration and remote livestock watering systems.

Equipment Systems: A well-designed and efficient water system is a very important part of a farming operation. Dugouts are large reservoirs of water that can be pumped at a much faster rate than most wells on the Prairies. This is only an advantage if the water intake, pump, and water distribution lines are sized to meet the peak demands of the farm. Dugout aeration systems can make a dynamic improvement in dugout water quality. Remote watering systems that pump out of pasture dugouts help protect livestock from illness and injury as well as improve water quality and livestock production....Read More

Module 6: Water Quality for Domestic and Human Drinking Water Supplies - Identifies the health risks and water testing procedures necessary for guaranteeing a safe dugout water supply.

Domestic and drinking water supplies have higher quality requirements than most other uses. Water that appears to be acceptable based on visual appearance, taste, odour, and colour may contain contaminants that affect human health. Risks can be chemical or microbiological. It should be remembered that water that has been successfully treated for human consumption might become recontaminated and present real health risks. Re-contamination sometimes occurs in the distribution system.

On the other hand, water that is otherwise harmless may have such objectionable appearance, taste, and odour that it is unacceptable for household use....Read More

Module 8: Dugout Management - Looks at ways to monitor changes in dugout water quality and apply treatment strategies such as aeration and chemical control of algae and plants.

The goal of dugout management is to protect and improve water quality. Some of the strategies for doing this through dugout location and design have been discussed in Module 3 – Planning. This module provides suggestions for preserving and enhancing water quality in existing dugouts. The cost and effort to properly manage a dugout is generally small and most often rapidly recovered in the form of improvements in water quality. Improving water quality reduces treatment costs, improves productivity of livestock, and generally improves the quality of rural life.

At a minimum, dugouts need to be inspected weekly during April to September and monthly from October to March. Early detection of problems allows corrective action before water quality deteriorates significantly....Read More

Module 9: Trouble Shooting Guide for Dugout Problems - Provides tables to assist with the diagnosis and solution of dugout water supply and quality problems based on the symptoms observed.

Dugout problems fall into two broad categories: water quantity and water quality. Problems can result from the watershed; the dugout location, design, and construction; the systems and equipment for pumping, aeration, and treatment; as well as management practices. This module is designed to identify the source of a problem and provide suggestions for correction. The troubleshooting guide starts by identifying typical symptoms of water quantity or quality problems. It systematically lists possible causes, identification features, suggestions for corrective action, and references for further information within the manual. ...Read More
