Where does MPCA get its data?
The data viewer application presents daily, annual, and period average water quality data from monitors and stream monitoring sites throughout the state.
Daily values are a mix of observed and modeled values, and the source of annual and average values. There's a two-year delay between data collection and publication to allow for data analysis and review.
