Matt Kocian, Rice Creek Watershed District <br />4/22/2024 <br /> <br />Notes: <br />• Our last rigorous statistical test of trend (Mann-Kendall) was completed in 2018. <br />At that time, no statistical trend in TP or Chl-a was found. Looking at the data <br />since then, I’m confident that no statistical trend has emerged – Karth Lake <br />continues to have no statistical trend, up or down. <br />• 2023 was a good year – all parameters were better than their 10-year averages. <br />TP was 12% lower, Chl-a was 71% lower, and Secchi was 32% higher than their <br />10-year means, <br />• Overall, Karth Lake continues to have very good water quality. It easily meets all <br />State Standards (e.g. not impaired). <br />
