| Comments | Observed by ODNR Fisheries staff during annual sampling. Multiple locations throughout waterbody. From N. Radabaugh: Most of the shoreline sampled had thick patches of hydrilla in water less than 6ft, and shallow bays were even more extensively covered. Some of the worst areas seemed to be in the Big Run arm of the lake (the west arm where the lake breaks into two). This area is shallower than the main lake and had areas of hydrilla growing from shore out several hundred feet into depths of around 8ft. |
