What are the steps to convert a sediment basin to a wet pond?

• A. Dewater, Dredge, and Regrade
• B. Dredge, Regrade, and Dewater
• C. Dewater and Regrade
• D. Dewater, Dredge, and Remove

Answer: (A)

Converting a sediment basin into a wet pond requires a practical sequence: remove the water, remove the accumulated sediment, and then shape the basin to the desired final form. Dewatering first is essential because with the basin drained you can access the floor, inspect structures, and perform large earthwork without the interference of standing water. Once it is dry, dredging follows to physically remove the built-up sediment that has filled the basin and reduced storage capacity, so the pond can hold the intended water volume and the outlet structures function correctly. After the sediment has been removed, regrading is done to establish the proper bottom elevations and side slopes for a functioning wet pond, ensuring the permanent pool depth and safe, stable geometry around the outlet and embankments. Skipping dredging or trying to regrade without removing the sediment would prevent achieving the required water storage and drainage performance, so the three steps in that order best accomplish the conversion.
