As a prerequisite to updating this plan in 2018 and to compare how the lakes vegetation had changed since the last point-intercept survey in 2014, the BCCLA, Lake Education and Planning Services, LLC, and the Wisconsin Department of Natural Resources authorized a full point-intercept survey for all aquatic plants from July 28-29, 2017. During the survey, we found macrophytes growing at 201 sites (20.7% of the entire lake bottom and in 57.1% of the 11.5 littoral zone). This was a moderately significant increase (p=0.002) from the 148 sites with plants in 2014 (15.3% of the lake and 30.0% of the then 14.5ft littoral zone), and a near return to the 269 points with vegetation (27.7% of the lake/68.6% of the then 12.5ft littoral zone) we documented during the original 2008 survey.
The Big Chetac and Birch Lakes Association is sponsoring a project to collect baseline water quality and habitat data for Chetac and Birch Lakes, conduct fishing success surveys at resorts, and support stakeholder planning committee meetings.
Project deliverables include all monitoring and mapping data, stakeholder committee meeting agendas and minutes, fishing success survey data, and a final report summarizing the results of the project.
