Just out of curiousity, how deep is the 3/4 acre pond? Those surface temps are pretty high for trout survival, do they show any stress or do you have any die-off? Now will the bottom pond be fed with outflow from the top one and if so is it overflow water or drawn from the bottom? My concern about mixing the water cloumn would be more from the 750 gpm running down your waterfalls/streams then from the springs... I am not sure how much cooling you can expect from the trip through the shaded area... do you plan tyo build a pool of some kind at the top? How long of a run through the woods do you expect?
