The hole is about 10' wide, 3-4' deep and maybe 50' long, formed by scouring of water at highway thru 2 box culverts. Fence crosses it and there are tree limbs, cast net would be difficult to use. Am near Waco, Tx.
Will probably put a metal tank in the back of pick-up to save some fish of interest, if I run across any. The mud-cats however are the species I most want to prevent from entering pond.
