Is it difficult for salmon to go up fish ladders, and if so, why?

Engineers design fish ladders to make it easy for fish to ascend. Each step of the ladder is a gradual increase in height and there are places for fish to rest. Usually a ladder is put in a place that is difficult or impossible for the fish to pass any other way. It can be hard for the fish to find the ladder, especially in a big river.
