The prairie potholes in the North-Central States and in Canada are of glacial origin. Because many of them contain ponds or marshes, they are important in the production of livestock and waterfowl. The objective of the present investigation is to determine the amount of water that accumulates in and is used in the potholes in their natural environment.
Two study areas were selected in North Dakota, and construction of gaging facilities was completed in 1960. Each study area contains four potholes. Three of the potholes for each area contain dense growths of aquatic vegetation, and one is clear of aquatic vegetation. The instruments to provide the basic data for computing water losses include: water-stage recorder, water-temperature recorder, rain gage, anemometer, and hygrothermograph. Observations will also be made of ground-water levels, rate of growth and type of vegetation, and quality of water.
