Check this out they have cabins for rent that are lake front, most do not have a private dock but you can moore by just tying up any where near your cabin. Also there are campsites here that have lake frontage.
Also at the seven-points recreation area there are several campgrounds that have lake frontage and mooring is allowed right at your campsite,no dock.
I spend the month of October at this lake and camp at Point camp at the seven-points recreation area where mooring is available along the bank next to your campsight.
Don't want to discourage you but I stay away from the place from memorial day until after labor day.expect it to be very crowded during the summer months when school is out.Don't know how the economy affects this place but in a good economy you would have to get your reservations in very early.
Hope this helps PM me if I can help in any other way.http://raystownresort.com/
