Just moved from a private lake in WA where tubes out number skiers, wakeboarders, and barefooters combined. Lake sat empty a majority of the time.
I sold to be closer to grandkids and downsize in retirement, but over the 14 yrs I lived there watched the # of course & tournament skiers decline every year. Saw it change from waiting to get a set to become not being able to find a driver.
Access wasn't an issue, but more recent owners seemed more interested in living in a gated community then being on a ski lake.
