Abstract

The water resources within the Lake Traverse Indian Reservation consist of streams, lakes, wetlands, and groundwater stored in alluvium and glacial outwash deposits. Streamflow may cease during dry periods and during the winter. Lakes and ponds within the reservation are found predominantly within an internally drained basin. Dissolved-solids concentrations in the lakes generally range from 500 to 10,000 mg/L. Dissolved-solids concentrations in the streams generally ranging from 500 to 1 ,000 mg/L. However, nutrient concentrations tend to be larger than natural background levels in both lakes and streams and indicate unidentified sources of nutrients that effect the quality of water. Major development of surface-water resources is hindered by the lack of storage capacity within the numerous lakes, the lack of sustained streamflow, and the lack of suitable sites for construction or reservoirs. Water within the Coteau des Prairies, a glacial upland, occurs in outwash deposits. The sand and gravel deposits in the Coteau may be as thick as 70 ft. The quality of water from these aquifers generally is suitable for most uses, with calcium, magnesium, and bicarbonate the dominant ions. Water in sand and gravel deposits within the Red River and Minnesota River lowlands tends to have larger concentrations of dissolved solids than the sand and gravel deposits in the Coteau des Prairies. The quality of water in these deposits tends to be more mineralized than water in the sand and gravel deposits in the Coteau des Prairies. The regional flow of groundwater generally is to the east towards the Minnesota and Red River basins and west in the Coteau des Prairies. (USGS)
