I have heard the strip mine pits can be good, but I have never fished them. Farm ponds usually make excellent fishing spots just be sure to get the owners permission. The ODWC has lists of urban fishing ponds, quite a few in Tulsa in the old flood plains, they were built in the late 80s & early 90s to help control flooding, I haven't fished them in years though. The outdoor ponds at Bass Pro hold some nice size fish too.
