ROCK RIVER COALITION, INC: Badfish Creek/Lower Yahara River Microbial Source Tracking


The Rock River Coalition Inc is sponsoring a River Planning grant to help explain increasingly high levels of Escherichia Coli (E. coli) in Badfish Creek & the Lower Yahara River using microbial tracking to determine possible sources and guide recommendations to help mitigate the problem for the protection of recreational users of these systems. Project Activities Include:1) Sample 9 different sites on 10 different dates from February 2020 to July 2021 for E. coli bacteria and send samples to the Wisconsin State Laboratory of Hygiene for analysis using microbial source tracking methods; 2) work with WDNR and Dane County Land and Water Conservation technicians to document any manure runoff events on lands with either Confined Animal Feeding Operation (CAFO) stacking permits or small farm nutrient management plans (NMPs) along either stream during the 20 month sampling period; 3) Record testing process with a video; 4) schedule educational workdays in coordination with Stoughton High School as well as other interest groups Project deliverables include:1) Graphs of the sample data will be created and correlated with graphs of E. coli testing done in Rock County during the same period and with a graph of the disinfection/non-disinfection schedule dates; 2) Provide a record of any documented manure runoff from permitted headland manure stacks or small farms with NMPs; 3) Create a presentation to be shared at meetings with Rock County Public Health Department, Madison Metropolitan Sewerage District and Wisconsin DNR It is recommended that Grantee provide the DNR water quality biologist with a draft for comment on report adequacy prior to making final payment to the consultant. It is recommended this be submitted 60 days prior to the desired final approval date to give adequate time for adjustments due to the size and complexity of this project. DNR to receive an electronic .pdf copy of the final report along with, or prior to submission of grantee's final payment request
