On May 8 and 10, 2017 an herbicide treatment with endothall on five Potamogeton crispus-Curly leaf pondweed (CLP) beds occurred totaling 21.34 acres. A pretreatment survey and post treatment survey revealed a statistically significant reduction in the CLP after treatment (comparing the 2017 pretreatment CLP frequency to the 2017 post treatment CLP frequency) from 70.4% to 12.0% frequency of occurrence. The 2017 post treatment CLP frequency of occurrence was higher than the 2016 post treatment CLP frequency, from 4.6% in 2016 to 17.6% in 2017. The pretreatment survey from 2016 compared to the pretreatment survey from 2017 showed a small increase from 48.1% in 2016 to 54.0% in 2017. There was one native plant species with a significant reduction and one native species with a significant increase. The 2017 turion analysis resulted in an increase in turion density from 2016 (38.1 turions/m2) to 2017 (71.2 turions/m2). A whole lake meander survey was conducted for CLP and a new bed of CLP was located in the main lake basin. Other CLP locations from 2016 were not present in 2017.
