i have about a 1/8 acre pond and i am considering doubling it's size to about 1/4 acre or a little more maybe... its 2.5yrs old now with fish. wondered how that would effect the fish and the pond in general by doing this? its a oval and my plan was to dig another oval then connect them as the last move by digging out the middle, ultimately giving it more of a peanut shape.

MY POND: 50'X100' (1/8 ACRE) dug in 2006. get's deep quick with a trench dug in the middle that reaches 17' deep. i have aeration. i stock bluegill, bass, trout, and perch and couple crappie.
