It's a traditional parkland layout with either lakes or streams in play on eight of the holes, 45+ sand traps, and numerous dog legs along tree-lined fairways. Designed by Roger Packard in 1980, the course plays to 6,541 yards from the back tees, with 71.1/126 course/slope ratings with two shorter tees.
