With a 5' minimum depth, it will be hard to avoid fish kills in your location. Distance to electric may not be as economically prohibitive as you think for aeration if you cover the distance with an air line rather than electric.
I'm guessing this is because it will get too hot in summer and too cold in winter plus the solid freeze would trap gases, etc...? So would the only option be to dredge? If so, how deep would it need to be ideally? I was already tipped off to the idea of running air line instead of electric and am reading up on that now.
