English: The present-day fish ladder at Bonneville dam is a pool-and-weir fish ladder, completed circa 1974. However, there was at least one earlier fish ladder there. This category includes all fish ladders at the dam, because identification is not always easy. Subcategorization to distinguish particular fish ladders would be welcome.
