Birch Creek - St Route 343 to Little Miami at Jacoby Rd. **Access Restricted** (OH)
Approximate - nearest available gauge. Use as general reference only.
At 2/3rds mile, Birch Creek ends as you confluence with Yellow Springs Creek. It has ~4.92 sq.mi. drainage at this point, thus (most likely) meaning from here to the Little Miami, you'll have slightly more than double the flow.
