i bought a house about 1 and 1/2 ago. been deployed most of this time. have huge, and i mean HUGE hole in back yard. imensions are about 115' long and about 45' wide. i am thinking of turning it into a pond was wondering what i should line it with posible aeration procedures and type of fish. my major concern is mosquitos in the summer. i live in virginia and they get pretty bad around here as it is. the only proble i see with this is that everyones yard around me drain into mine. the question i have is would it be worth it to put in a pond or maybe fill in first. i will try to get a picture and post it tommorow. any help would be greatly appreciated. pretty much new to the whole home owner/gardener scene.
