lowhead dam


lowhead dam
a dam extending across a river of low height, usually 15 feet (about 5 metres) or less. It impounds the water behind it, has minimal effects on the downstream regime and allows water to fall over its whole width. Quite dangerous as boaters and swimmers may not see it until too late and can be caught in the backwash beneath the dam. Also called channel dam or run-of-the-river dam
