What would indicate a bale barrier is not performing as intended?

• A. Runoff flows under/around/over/in between the bales
• B. All water is stopped by the barrier
• C. The barrier becomes permanent and unmaintained
• D. The bales wrap around the posts

Answer: (A)

Bale barriers are meant to slow and capture sediment by intercepting runoff. The clearest sign they’re not working as intended is if runoff flows under, around, over, or through gaps between the bales. That bypasses the barrier and allows sediment-laden water to continue downstream, showing the control isn’t performing its job. Keeping water from all flow isn’t a realistic expectation in practice and would indicate perfect performance, not a problem. If the barrier becomes permanent and unmaintained, that’s a maintenance/design issue that can lead to failure over time, but it isn’t the immediate field indication of current performance. Bales wrapping around posts signals installation or damage problems that can impair performance, but bypass of the barrier is the most direct indicator.
