We have no sewers just drywells, which only have a 5000gal capacity so draining 300,000 isnt realistic.
I sincerly doubt it has ever been dredged before either.
I have read about underwater air diffusers which would seem fairly simply to install but I'm not sure if it would help my situation.
Also I spoke to a local pond specialist yesterday who suggested a wetland bog filtration system for the bargain price of 20K which he swears will work but just isnt in the budget.
