Many of Wisconsin’s water quality standards require multiple visits to make an assessment decision. Every year, several stream sites are monitored and the field data collected during each visit are used to “flag” problem waters. In the next year, follow up monitoring is carried out on the “flagged” waters where the data suggest there is an impairment, but there are insufficient data to make that determination based on the State’s minimum data requirements. In 2015, stream monitors assisted in the monitoring process by collecting water samples to be analyzed for total phosphorus at the Wisconsin State Lab of Hygiene.

Historic water quality data, used as part of the Shawano Lake Watershed Assessment (UW Stevens Point - Center for Watershed Science and Education 2008), indicate that total phosphorous levels exceeded the impaired listing threshold in several of the tributaries to Shawano Lake. DNR staff and WAV volunteers began collecting total phosphorus data for these streams in 2013 and have continued in 2014 to fill any remaining data gaps.

In 2013 NER region monitoried and sampled 8 stream segments and 1 lake site for impaired waters considerations. 6 of the 8 stream segments indicated impaired biological communities which are identified for additonal impaired waters monitoring in 2014 of the biological communities. In additon 6 monthly TP samples will be collected to identify the suspected pollutant as TP in all 8 stream sample locations. The lake sampling site on Mud Lake will again be sampled at spring turnover, June, July, August, and September for TSI criteria. NER proposes to monitor 6 streams and 1 lake which are tributaries to Shawano Lake during the 2013 project cycle for impaired waters identification. Historic water quality data from the UWSP- Center for Watershed Science and Education in their Shawano Lake Watershed Assessment (2008) indicates that Total Phosphorous samples have exceeded the listing threshold in these streams. The 6 streams will be monitored for biological impairments by conducting fish and qualitative habitat surveys, collecting macroinvertabrate samples, and continuous water temperatures. Chemistry samples will be taken on Mud Lake for Chlorophyll a and total phosphorous. Flow and basic Water quality parameters will also be collected during each field visit. It is anticipated that this will be a 2-year project so that 2012 WisCALM Guidance can be followed for TP listing with biological impairments. The 6 monthly TP samples will be proposed on those stream segments in 2014 that show biological impairments from 2013 monitoring to fill remaining data gaps. The second year will also include the remainder of growing season lake monitoring for TP and Chl a.
