Good spot to fish certain times of the year. Boat traffic here is heavy. If you want to fish the river on a Saturday, good luck as people with yachts want to run the river when the channel is only 25 yards wide in some spots. Lake is nasty green from July through mid September. There are better fisheries within the state and a lot less traffic in the summer

The lake has always had wind erosion to contend with. Now there is extensive boat traffic that is causing extensive erosion of unprotected shores which fills in the deeper holes. Along with modern technologies and winter draw downs are decimating the sport fish populations. IMHO. Joe Due

This lake is a proven producer for big pan fish! I have caught just about every species of fish on this big brown lake! I even caught a five pound catfish on my jig pole through the ice one year! If you haven't fished this lake in the winter, be cautious. The ice can be "tricky"! Plus it is almost always windy! We have had to chase buckets and shacks across the ice! Good luck!
