Bender,
Without supplemental cold well water at a rate faster and more in quantity then you are apparently going to provide, I think your pond will get too warm at some point in the summer for trout. I also see your underground pipes clogging with algae that gets sucked into them. I have underground overflow pipes up to 6 inches that still have debris buildup no matter what I do. I even screen them! My present underground 6 inch pipe can no longer handle about 40 gpms of overflow! I have finally gone to an open trench to run my overflow away from the trout pond.
With the juice you use for your 11,000 gph pump (about 183 gpm) you could easily power a well and accomplish the same thing cheaper.
Just my two cents and I could be wrong.
You could have trout from fall to spring if you don't want to run the well water. No need to run well water then. I shut mine done the beginning of November and don't start it back up until April of so. (depends on the how fast it warms up in spring). And that's with the equivalent of 5000 pounds of fish per acre.
