The Northern Great Plains Inventory and Monitoring Network (NGPN) began monitoring water quality in the Knife River at Knife River Indian Villages National Historic Site (KNRI) in 2013, with the assistance of the U.S. Geological Survey (USGS). This report summarizes the data collected during the 2016 ice-free season (March 10 through November 3) for streamflow, water temperature, dissolved oxygen, specific conductance, and pH. 2016 was a moderately dry year and discharge on the Knife River peaked at 800 cubic feet per second in April. There was considerable seasonal variation in all water quality measures. A summary of our results can be found in Descriptive Statistics Summary tables for the ice-free season (Table 2) and for each month (Table 3). Notably, water temperature exceeded state standards in summer months although these exceedances made up less than 2% of all records. NGPN’s collaboration with USGS supported real-time and archived access to this data through the USGS National Water Information System Website, where it remains available to the public.
