Out for another walk on the lake and thought this area was missing a cache. When the cache was placed, the water was much lower than usual and seemed more blue. Maybe that was just because the last time was I was there it was foggy...
Anyway you can walk a little ways from GZ and have a nice view over the lake on the "observation deck." There you will also see the meter on the side of the deck, which will tell you how high the water level is. Lots of frogs there too.
Enjoy the walk and enjoy the cache!
