Side channel spillway at
Hope Dam in Scotland
Side channel spillways are used mainly with embankment dams. They are located just upstream and to the side of the dam. The water flows over the spillway, into a side channel.
Spillway chute from
side channel to river
Then it flows down a chute and joins the river downstream of the dam. Sometimes, a tunnel is used which may divert the water elsewhere.
