  • Don't let the size of this lake fool you, it's a ton of fun. Fishing, boating, swimming, kayaking, etc. Will fill your day with a ton of fun. The lake is really clean and has natural coal so it may be good for your skin. This lake is cheap and very worth a visit.
  • Really beautiful!!! The camping sites are really well layed so each has a nice view. Only draw back is there is only water and electric, with no showers.
  • Nice camping area. Great fishing for my boys. enjoyed our 1 night.
  • Easy gettaway!!! Their policies are fallowed if not the lake police see that everything's taken care of.
  • Grew up on these waters. I love it here. Anytime of year.
