This video clip was captured from a boat while collecting water quality samples on the White River on April 20th, 2011. The gage height at the time was 17.39* feet and discharge was 32,900* cubic feet per second. The conditions seen here are considered bank full, which is the point at which the flow of the river completely fills river channel.

The Maple River Dam is a pass-through dam that lets a limited amount of water flow through year round and fills the reservoir only during high flow. If the water rises high enough to fill the reservoir, water flows over the spillway shown in this photo. Video taken at the same time is available online.
