try going in the Springfield lake park entrance. Take the small road until you see the turn in for the children's playground. Drop the kids off, if you have them:D then go down the hill to the water. There are a few open spots down there. If you're after perch, no problem, throw some worms, or chicken livers for catfish and perch. For bass, continue on down to the lake house at the end of the road. Try to hit the wooden stumps with a crankbait or spinnerbait
good luck
