#1 Broad Crested Weir

Description: The Sixth Street Dam, or more properly the Sixth Street Broad Crested Weir, is located near downtown Grand Rapids, Michigan on the Grand River.  It was constructed originally to power furniture mills but currently has no direct application.  Typically, there is a six to eight foot vertical drop from crest to the downstream water surface but in flood conditions this can be reduced to only two or three.  The Sixth Street Dam is also fitted with a fish ladder to allow migratory fish, like salmon and steelhead, to pass and continue up stream.
