I can only chime in with my similar situation. I get ~ 60 acres of Ag run off feeding my pond. It does go through two silt ponds and some grass, which helps. BUT, last fall we received 13 inches (yes, 13) over a 2 day period, which turned the pond into chocolate milk for almost 2 weeks. I continued to run aeration non stop throughout (even though I wondered if the turbulence from the diffusers would prolong the particle suspension). No overt evidence of a fish kill later in the fall, and good ice fishing this winter.
And in the past 5 days, we've gotten over 5 inches, with some coming in 1 or 2 inch gully washers. Pond is again chocolate milk color, with a white jig invisible in 2 inches of water. I continue to run the air and fret. I'm gonna be positive and say it'll be okay.
