Why are dam gates opened?
Why and when are dams open or closed? A dam operator can usually control the flow of water and the size of impoundment by opening or closing gates. Gates might be opened when water levels are high and the impoundment needs to be lowered, and may be closed if water levels in the impoundment are low.
How do gated dams work?
A gated dam is built to enable Seqwater to have some control over the release of water. Once a gated dam reaches its Full Supply Level, we control the release of water over the spillway using specially designed gates. Gated dams can mitigate flood impacts by controlling the release of water.

How do dams stay stable?
Consequently, the water’s downward force against the bottom of the barrier greatly exceeds its horizontal force against the barrier’s unfolded wall. By harnessing the water’s weight in this proportion, the dam adheres to the ground, remaining stable.
Will water continue to flow after the gate valve is closed?
Sometimes a little water will continue to flow after a gate valve is closed as fully as possible. In some cases the plumbing repairs inside the property can be performed with a little bit of water flowing through the system. But there is an other option as well.
