A digital model was used to describe a ground-water system in glacial deltaic deposits near Kindred, N.D., and to predict the effects on ground-water levels of a planned lake at the 950-, 960-, 970-, 984-, and 995-foot stages. Model analysis indicates that only the area within a radius of about 2 miles of the dam on the present Sheyenne River would be affected by rising water levels as a result of a lake stage at 995 feet. The rise of water levels depends on time and hydraulic properties of the aquifer. The maximum projected rise in water levels at the various stages should occur in about 50 to 100 years. Evapotranspiration and existing drains will be effective in limiting the extent of water-level rise. (USGS)
