Fish Ladder
A fish ladder is a special structure built at hydroelectric dams and other water barriers that helps fish swim upstream to spawn. Think of it like a water staircase or ramp that allows fish to bypass the dam by swimming through a series of small pools that gradually rise in height. This is important because many power companies must maintain these structures to meet environmental regulations and protect local fish populations. When this term appears in resumes, it usually relates to experience with designing, maintaining, or monitoring these passages as part of hydroelectric facility operations.
