I've lived in a private gated four lake community (avg of 12 homes per lake) and have also lived in a two-lake community which was very much like what you have outlined: higher density of lots at 'reasonable' prices, a limit of 15 'lake/boat use permits' per lake, but everyone could 'access' the lake, located in a very small town but within 40 minutes of a city with 2.7 million people, etc.
The four-lake community I miss every day… 48 other lot owners who had the same passion as I did, appreciated the lakes for what they are, worked to keep them in great shape, and (mostly) respected each other.
The two-lake community, even though we built a beautiful home that my wife still says was her favorite, I could not leave fast enough. Sold after living there 2.5 years. At that price point, at that density, there was not the appreciation of a private ski lake with a slalom course. Other than a few of us it was full of weekend warriors who felt it was there right to do as they pleased, partied as much as they'd like at all hours of the night (city had no noise ordinance, so the police were no help). When I skied it usually involved 30-60 minutes of fixing the course beforehand. Make a pass down the lake and come back for another only to have kayakers paddling down the center of the course. Or another boat coming straight at you because they felt your 10 minutes were up. I could go on and on.
I commend you for what you are undertaking, and I hope you are successful, but unless you are in an area that can support that many homeowners who understand private lake/slalom skiing living you really need to nail down your CCR’s and Lake Use rules and enforce them.
