CONTINUOUS WATER QUALITY MONITORING FOR THIS SITE IS OPERATED SEASONALLY


The precipitation data for this station are temporary and will be displayed only for the most recent 120 days. While the instrumentation is calibrated at least annually by the National Weather Service, standard USGS quality-assurance measures are not performed that would make the data acceptable for archival, retrieval, or future use in general scientific or interpretive studies.



Station operated in cooperation with the Michigan Department of Environment, Great Lakes and Energy, with financial assistance from the USEPA Great Lakes Restoration Initiative.
This station managed by the ESCANABA FIELD OFFICE.
