Your mix of fish sounds ok. I am suprised you have been able to keep trout throughout the summer. I have a simular pond in both size and depth in about 40 miles east of you and loose my trout every summer. I have used Haretta Hills fish farm and they charge about $100.00 for delivery, have allways had good luch with their fish. I am pretty sure there is also a fish farm in Rose City as well. Good luck!!
