Stream Monitoring and Assessment

Stream monitoring

Metropolitan Council Environmental Services (MCES), with assistance from local partners, operates long-term, automated stream monitoring stations. We currently collect both water quality and flow information at 22 stream sites, and biological information on macroinvertebrates at 14 of those sites.

WOMP Sampling Dashboard

WOMP cooperators can use this dashboard to observe when autosamplers have registered a sample.

Stream assessment

We assess the data collected through our stream monitoring programs to characterize the conditions of individual streams, determine the extent and sources of point and nonpoint-source pollution in the metro area, and track water quality trends over time.
