Pond Boss Forums AERATION Systems questions How to aerate a long, thin retention pond system?

I'm a complete noob to managing ponds and am struggling to determine the best way to aerate our HOA's retention pond system. Map of ponds attached, but the pond forms a rather thin "U".

The East and West arms are connected by a culvert on the South end. Additionally, the entire south end is very shallow (1-3' max). We'd like to dredge to get to 4-6' prior to adding aeration. The rest of the pond is probably 3-6' deep other than corners on the north end.

Let me know if any additional info is needed. Any advice is greatly appreciated!
