I'm brand new to this forum. This happened to be the first thread I read so here's my 2 cents worth.
I needed a couple hundred yards of dirt so dug a borrow pit in 2005. Drained it down to less than a foot and doubled its size in late 2007. It is now about 1/3 of an acre and about 10 feet deep.
No fish were ever introduced into it until this spring. It is filled with runoff from 30 acres of farm land and the overflow is never under water in the ditch it drains to (which is dry except after rains).
Just before I went to buy some blue gill and channel cat to stock it, I found over 300 hundred blue gill 1-4" in size schooling and sunning themselves.
I'm not going to speculate how they got there but there they were. As best I can tell, blue gill is all that showed up on their own.
