Grew up in Springfield and still here, I also stay at TableRock. Yes, many of the old storm drains about 5' high and 8' wide use to flow to Jordan Creek and into Wilson Creek, and out to the James, all that was redone 25 to 30 years ago, walled off and redirected with pipe. The old "tunnels" are still there if ya know where the access points were, just blocked now with a thin concrete wall. Anyway, forgot what the thread was about...
Take care man and have a good one!
