Wisconsin Year 2020 TWA Water Quality Plans and Reports
While each study is unique, the core work conducted in each one includes surveys of fisheries, habitat, water chemistry, aquatic macroinvertebrate species. The timeframe for monitoring conducted in these studies varies, with a few areas monitored in 2015-16 and others with more recent monitoring.
To learn more about Targeted Watershed Assessment Monitoring, see DNR's
TWA Monitoring Webpage.

TWA Monitoring Projects statewide.
The objective of the Targeted Watershed Assessment monitoring study design is at its core a comprehensive snapshot of physical, chemical, and biological aquatic condition in the studied area. Effectiveness project studies evaluated the success of best management practices implemented in the 1990s, while protection studies identify the overall condition of some of state's most pristine waters and provide recommendations for future actions to maintain these likely healthy watersheds.
Evaluation studies are conducted to understand the potential for site specific surface water effluent permit limits or other WPDES related work, and overall general assessments provide comprehensive snapshots of water condition for DNR and partners to apply for grants or initiate other types of restoration, protection or implementation work in the watershed.
Water quality biologists and water resources field supervisors provide detailed analyses, monitoring recommendations, and management recommendations based on the data analyzed and statewide standards. The report summaries and recommendations reflect years of professional management experience,peer-to-peer collaboration and data analysis best practices,and critical connections with local, state, and federal implementation opportunities. Restoration and protection work may include TMDL implementation plans, County Land and Water plan implementation, and Nine Key Element Plans management design, and recommendations for funding under the state's Surface Water Grants Program,including lakes, rivers, aquatic invasive species, and runoff management project funding opportunities.
