Yeah sorry for the confusion. Normally I just lurk and keep my fingers from typing but I got excited when I realized where you were talking about. ;)
I guess what I was trying to get at is that it doesn't really solve the supply and demand problem. The people who would be interested in a private lake community in that specific location would have to be incredibly dedicated to watersports. So if you get high volume of people (100+ homes and 210 multi-family units, potentially 1000+ persons!) all wanting the same thing and paying a premium for it, it creates the same problem that was existing before: Too much demand, not enough resources. Say I have a family of 5. Thats at least an hour for each to have 1 turn. What about the other 25-30 families that want a turn that same night? What if I wanted to invited friends for a tug? I mean, you could say that maybe only 500 of 1000 people actually want to use the lakes. Thats still 500 people to share 2 lakes in 5ish months of warm weather.
This is how I look at it. Lets say the lakes are open from 0700-2100, 14hrs per day, 7 days a week. Thats 98 hrs of availability a week, times 2 for each lake, so 196 hrs total. Divide that by the 500 people 196/500=.39hrs, each person gets just under 25 minutes a week. That absolute best case scenario. Most people have jobs, kids have school, etc. and are only available in the evenings/weekends. Wind/weather restrictions as well. So in reality its much less that 25 minutes per person each week. You'd be lucky to get in 1 turn a week in my opinion. But it all depends on how you set it up I guess.
Hard core waterskiiers have 3 courses and private lakes within 30 minutes of the valley that they could potentially have access to. Plus, no permanent slalom course on the lakes... you most likely won't sell to any skiers. So your audience would be the average Joe who is an avid wakeboard/surfer or who is really weathly who could afford the homes and take an occasional tug. I just don't see how the balance of cost vs. time on lake pans out. That area has many other activities (snow ski, MTB, Hiking, rock climbing, dirt bike, RZR) that families could put their money into and just deal with the crowds at the local lakes.
But again, I haven't researched or marketed that area for this specific thing so this is just my obvservations/opinions. If it works out, I'm all for it.
