Benz Lake is private and has a max depth of only 8 ft. but holds fish on and off depending on the weather conditions. To my knowledge an aerator was in place, but failure to keep it operating caused a winterkill. Reports of walleyes up to 25'' and crappies in the 10 in. area before the kill(07' 08'). The numbers were also good. Could be something there, just need permission, good luck. Says Russ W.
There are plenty of people from Stillwater here at Benz
Lake. Stay the night at Lake Elmo Park Reserve Equestrian, and if you like skiing, you're in luck; Wild Mountain is relatively near.
