106 Water Quality Water Summer Workshop

The CRST 106 Water Quality Program grant was first awarded in 1993 by the Environmental Protection Agency. The grant's primary goal is the protection of our nations waters according to the Clean Water Act. 106 Water Quality Program objectives are determined from year to year by the CRST Department of Environment in Natural Resources. The cornerstone of the program is the establishment of the Water Quality Monitoring Program on the Cheyenne and Moreau Rivers. Four sampling stations on both river systems are presently being monitored. The two concerns the CRST Department of Environment in Natural Resources has with these river systems is agriculture and mining pollution. On both river systems numerous studies have been and are presently being conducted which include: Biological (macro invertebrate and periphyton) surveys, fish sampling, soil sampling, habitat surveys, as well as Water Quality monitoring.

Water quality in the Cheyenne River, Moreau River, and surrounding tributaries s affected by many natural and anthropogenic factors such as geology, effluent discharges, agricultural practices, irrigation return flows, and past/present mining practices. The Cheyenne River Sioux Tribe 106 Water Quality Program is addressing these factors through cooperation and understanding with all concerned: monitoring sewage lagoon discharges, developing stream restoration projects, and fixating on the people's needs are only a few of the goals set forth by the CRST Department of Environment in Natural Resources.
