One of the easiest to find. South on I-35 to Black Bear, Hwy 210, then west on 210, til a mile from Cromwell. You'll see the water tower, and if you go too far, you'll drive over the lake just before entering Cromwell. Take the last left before the lake and Cromwell. It has a DNR public access sign. You should be able to find this one.
As for fish, either Largemouth or pike are good choices.
