How Sediment Buildup Reduces a Pond's Storage Capacity

Every inch of sediment in a pond is an inch of storage capacity it no longer has.

During a big storm, that lost capacity is exactly what leads to on-site overflow or flooding.

It builds slowly, but the effect is real.

Across Chapel Hill and the Triangle, ponds that haven’t had a cleanout in a few years often carry more sediment than property managers realize. Tracking storage capacity is an important part of storm-season readiness.
