Additional Comments
One of two culverts at this crossing of County Line Rd and Stony Creek (along with SC05A to the south). The culverts are wide apart and each takes a branch of Stony Creek; the creek then rejoins west of County Line Rd. Area up- and downstream flooded, did not do riffle since it widens out into a flood plain/swamp.

Summary Information
A future visit to this site is recommended. The culvert has been pieced together- upstream is old and rusty, downstream end clean and new. It is not handling flow, leading to large flooded areas. If addressed, need to consider SC05A as well.
