2021 NFCRWD TROPHIC STATE INDEX (TSI) Carlson s Trophic Status (TSI), is a benchmark for lake water quality, by the Secchi disk, Chlorophyll 'a , and total phosphorus. Eutrophic (TSI 51-70): Decreased transparency, lack of oxygen in the lower levels during the summer, weed problems evident, warm-water fisheries only. Mesotrophic (TSI 41-50): Water moderately clear; some probability of no oxygen in the lowest levels during summer.
Grove Lake No Significant TSI Trend Exists Total phosphorus is decreasing, which indicates improving water quality (99.9% confidence). Secchi depth is decreasing, which indicates declining water quality (95% confidence).
Rice Lake Rice 209 South - Total phosphorus is decreasing, which indicates improving water quality (95% confidence). Rice 203 North - Mean TSI is decreasing, which indicates improving water quality (90% confidence).
Pirz Lake Mean TSI is decreasing, which indicates improving water quality (99% confidence).
Lake Koronis Koronis 211 South - Mean TSI is decreasing, which indicates improving water quality (99.9% confidence). Koronis 206 North - Mean TSI is decreasing, which indicates improving water quality (95% confidence).
