I spend a lot of time at the lake - in fact heading out there right now - and haven't found any local providers.  They are probably there, but way under the radar because it is a very small town so all the locals know each other.

You have two choices - take someone with you or try pick up a lady in one of the bars, at the sand bar, at Copper Canyon or in the channel.  Lots to choose from, but if you want a "sure thing" better bring someone.  I've done that a haf dozen times and have always had a blast.
