Possibly fished out...but I also think there's another possibility.
When I got news of this place, I went down just to check it out since I live so closely. There is only a very small area with access to fish and restricted against floating craft.
As such, and with 4 acres and significant depth, once the fish get acclimated and explore, they'll soon find that they can find a depth with comfortable temperature and can cruise around in peace away from the dock when there is too much pressure/noise/disturbance and just not reachable. So, there may still be a good number of fish still around for all we know, but just impossible to reach/catch if they're spooked by the crowd and hide out in the depths and/or the 98% of that water nobody can effectively fish.
What I mean by effective, is even if you can cast a mile and reach quite a ways, there's still no guarantee that's where the fish are cruising and more importantly no way to know what depth your presentation needs to be...they won't necessarily be on the bottom and how far do you suspend it to get to the fish?
Just some thoughts...I think there very well may be some holdovers in there.
