Welcome to the Friends of Hika-Bay Creek Monitoring Site.


The Site Map Seasonal Sampling link below gives access to all the current 2022 sampling data as well as the 2021 data results on a Google Satellite map. The link opens showing 2022 results for ecoli in the Centerville Creek Watershed. All of the results for Phosphorus, Nitrogen, Turbidity, Dissolved Oxygen, Stream Flow and ph are also available. Location names can also be selected. Sampling was also analyzed for Pine Creek, Calvin Creek and The Little Manitowoc River and can be selected from the web page. A legend is shown for the selected analysis and provides a link to current water quality standards.

Changes for 2022 include more sampling sites for Calvin and Pine Creeks. Sampling started in early June.

We need to understand the water parameters that affect us all! While water testing can be expensive and time consuming, we must collect benchmark data to develop and assess a management plan for Hika Bay. This data includes biological, physical, and chemical assessments of stream quality. An internship has evolved through a partnership between the Friends of Hika Bay, Lakeshore Natural Resource Partnership (LNRP) and the University of Wisconsin-Green Bay Manitowoc Campus. Student interns from the university are responsible for data collection and analysis of the watersheds of Hika Bay and the Little Manitowoc River on a weekly basis through the summer. This testing helps diagnose potential problems and establish a base-line of water quality. Once sampling is completed, LNRP will host a public presentation of the project results and analysis from the interns October 12 at the UW-GB Manitowoc Campus. Come meet your stream analyzer at this event and find out what is in your water!

For the summer of 2022, sampling for nutrient content and pathogens will be done every Monday morning and after rain events of a half inch or more from 25 locations. The site map details these locations and the Seasonal Sampling map shows results from analyzing the samples. The information is an important component to the Centerville Creek Restoration Project. Year to year comparisons will be made in an effort to detail water quality improvements due to the restoration. The wide area sampling information enables a comparison of how different land practices in each watershed impact water quality.
