Thanks. That's what I thought, but needed some confirmation by people who know a lot more.
Even though pretty new, my BOW not only stratifies, the bottom layer can become nasty. A year ago the water coming out the standpipe smelled like rotten eggs for a few weeks. This was during a prolonged hot & dry spell.
Will have to aerate at some point. I have an 80 yard (not feet) long island in the middle, which obviously reduces natural wind driven oxygen exchange, something Bob Lusk pointed out several years ago. Haven't done so due to lack of electricity and extra $ to pay for system, but now that the fish are growing and the pond has become more fertile I'm gonna have to bite the bullet.
