a big man-made pond. probly a 1/2 acre 12-16' deep.
fresh last year and plenty capable of sustaining fish year round.
what would you put in there so in five years it's sprawling with life?
id probably go with largemouth and some sort of panfish, bluegills, pumpkin seeds etc... You gotta have some sorta forage like shad as notaro said. A buddy of mine has a small pond that he put bass in, they are really skinny fish, there isnt enough food for them. These bass are bout 10 years old and might weigh 3 pounds after a good feeding.
