PHOTO OF THE DAY: Restoring lost capacity in shallow reservoir by Watermaster

A Watermaster amphibious dredger is restoring lost capacity in a shallow and hard-to-reach reservoir where larger conventional equipment cannot operate.

All reservoirs face the same problem: siltation.

Reservoirs store water for drinking, irrigation and hydropower, but siltation keeps reducing their storage capacity by 1–2% every year. That adds up to roughly 10–20% every decade.
