What is a fish ladder?
Quick Answer
A fish ladder is a structure built around a dam or waterfall to help fish move upstream. It provides stepped pools or channels that reduce the barrier created by the drop.
The Full Story
Fish ladders are used to support migrating species such as salmon, shad, and eel that need to reach upstream spawning grounds. By creating a series of small drops and resting pools, the structure makes passage possible at a barrier that would otherwise be too steep. Designs vary from simple step pools to more advanced fish lifts and bypass channels. They are a common part of river restoration and dam management.
