With a temperature profile like the one shown above AND with water clarity of at least 4 ft with 11 ft of pond depth and no aeration you should grow trout in that pond until the water clarity drops to 3ft. When that happens in July -Aug the trout will very likely die. I suggest that you perform two more temperature profiles. One in mid July and one in mid to late August. Also record water clarity with these tests. Use a Secchi disk or a home made all white one for most accurate clarity measurements. Clarity measurements will provide a good idea of depth for DO production. Post the results here in this thread. This info will give a good idea how well trout might survive next year if your water stays with 2023 clarity of 6-7ft for a 11-12 ft deep northern pond.
@Bill Cody, here is the updated temperature profile, now that I have
my aeration system up and running for about two weeks. Wow, I am amazed at the temperature uniformity! Water clarity remains 6 to 7 feet with a Secchi disk. The only fish in the pond are FHM, and there are thousands of fry hanging around the plumes of the two airstations.
I am sad to see the cold, deep water fish haven disappear, but I assume the lack of a thermocline is less risky to fish and aeration is better overall for the health of the pond.
Recall, this is a newly dug pond, only 8 months old. My plan is to stock trout this fall for put and take fishing until next spring/early summer. Then, introduce YP, RES, and SMB next year.
