The Department of Agriculture and Natural Resources maintains an extensive surface water quality monitoring network at many of South Dakota's streams. There are currently 153 active ambient monitoring stations across the state. The data from these sampling stations helps the Department identify problems, document improvements and demonstrate overall trends in the quality of South Dakota waters.

As stated above, South Dakota conducts sampling at numerous stream sites throughout the state. This information is entered into a national database called "WQX," which stands for Water Quality Exchange.
Water quality information from these sites can be obtained from the Water Quality Portal, and is used to develop Surface Water Discharge Permits and evaluate ambient stream quality. For more information, contact Aaron Leingang or by calling (605) 773-3351.
