Chatfield = if you can get there on a week day and especially if you can get there around 6am otherwise there is no use of it..
Sloans = Favortie private lake .. deepest part of the lake is 5ft though but insanely warm during the summer and private lake = king ... glass allll dayy and everyone who goes there pretty much wakeboards and is very friendly... but dont be shocked if you find a body or gun on the bottom
Aloha Beach = Coolest private lake Ive been to its like where you would never expect a lake to be in a neighborhood right off a major road ( dont worry is quiet ).. its narrow but long lakes ( 3 ) and pros ride there all the time ( liquid force team ) with houses around all of them and your backyard is sand and everyone is VERY VERY friendly there and cool luckily I have a friend who lives on there ... houses are anywhere from 600k to 3mil prob but you get your dock and your lake obviously... and if you dont mind sharing the lake for like 30-45 min intervals you would love it and everyone is pretty cool about your time limit on there and when your time is done just hop in the boat thats next and go again haha! :-D
