Fish ladder near the south shore of long island, where recorded alewive migration was occurring. Dams, waterfalls, and locks are all examples of obstructions that impede fish migration patterns. Fish ladders provide a detour route for migrating fish so that they can get over or around a dam that's blocking the way.
How Does The Brenke Fish Ladder Work?
Fish ladder is constructed to allow fishes to pass over a dam by providing water velocity which a fish can negotiate while moving upstream. Fish ladders are small elevated steps or passes made in dams, with water releases to enable fish to migrate in the upstream (or downstream) of the dam. A fish passage that is designed to allow fish to pass upstream may not allow passage downstream, for instance.
