There was macrophyte growth to the bottom. Lots of damselflies observed. Typha latifolia, Potamogeton praelongus, Aphanizomenon sp. The calculated TSI is an estimate. All valid TSI values are indicative of an eutrophic lake.
Secchi values are invalid due to small sample size.
The large plant population and considerable algal growth are additional indicators of an eutrophic lake. Osprey, lots of ducks and geese. Plants growing throughout the lake, could not get secchi depth. Pulled Lythrum salicaria in one area, could not easily access another spot. Shoreline with Scirpus and Nuphar nearly throughout.
