....like 1600.
I came across this on Flyfisherman. Ironically my wife grew up about 3 blocks from Green Acres Pond they refer to in the article. It's a put and take drainage pond for the streets of Clovis, and not a place I'd eat any fish out of due to the nature of street runoff, yard runoff, and the inherent chemicals/oils/etc in the water. Surprised the person could actually catch that many fish out of that sink hole (probably about 3-4 acres in size.
