2019 Big Green Lake TWA WQM Plan (2017)

Purpose

This TWA will reassess the water quality of the southern Big Green Lake sub-watershed (HUC-12 040302010902) after watershed and instream BMP work was completed to evaluate its effectiveness. A TWA in this HUC 12 was assessed in 2014 for baseline (pre-restoration) data.

Objective

The 2014 TWA (See attached document) involved collection of a baseline water quality assessment on the south side of Big Green Lake including total phosphorus (TP), habitat, fish, and aquatic macro invertebrates. In 2019, the intent of the TWA is to repeat the TP, habitat, fish and macroinvertebrate monitoring to compare the aquatic community and nutrient concentrations pre/post BMP installation.

Outcome

All inorganic chemistry and macroinvertebrate data will be entered into SWIMS. All fish and habitat data will be entered into the FMDB by Water Resources staff. A final report comparing the 2014 TWA to the 2019 TWA will be uploaded into SWIMS by 12/31/2020. This TWA supports Big Green Lake's partners' efforts to reduce the TP entering the lake. The Big Green Lake LMP Team is comprised of Green Lake Association, NRCS, USGS, Green Lake and Fond du Lac County LWCDs, and Green Lake Sanitary District. This also meets the monitoring plan recommendations within the submitted 9KE application.

Study Design

Methods, Equipment and Quality Assurance: Collection of TP, habitat, fish, continuous temperature, and aquatic macroinvertebrates used standard DNR data collection methods and samples were sent to certified laboratories in the state. No specific in-field duplicates, replicates or blanks were collected for the study; however quality assurance sampling procedures were used in the collection and preservation of samples for all parameters.

This Targeted Watershed Assessment (TWA) will address needs for baseline water quality monitoring of the watershed on the south side of Big Green Lake. This watershed discharges between 15-30% of the Total Phosphorus load into Big Green Lake. Considerable stream restoration and watershed BMP work has been done and is projected for the future by multiple agencies, including Green Lake County LWCD and NRCS.

ATTAINS Follow-up monitoring conducted
Monitoring the Big Green Lake watershed will be used for comparison of future monitoring after watershed enhancements have been made to improve water quality in Silver Creek and reduce the nutrient and suspended solids load into Big Green Lake. Considerable creek restoration and watershed best management practice work was conducted and is projected for the future by multiple agencies, including Green Lake County Land Conservation Department (Green Lake County LCD) and Natural Resource Conservation Service (NRCS).
