Salmon use their sense of smell (olfactory organ) to return to the place in a stream in which they were born. The fish have an instinctual desire to complete this journey at all costs.Fish ladders provide a way for migrating fish to get around obstacles like dams.
Hydroelectric power has been touted as the 'environmentally clean, renewable source of power.' This is subject to debate, as hydroelectric dams use turbines to generate electricity, and these turbines are spun by shafts which have blades on them. Fish which get caught in the high-pressure streams of water directed at the turbine blades usually do not survive the encounter with the blades. Also, the impoundments, or lakes, behind hydroelectric dams slow the speed of the river so much that many young fish do not survive the long swim to the ocean, where food is plentiful in comparison to rivers. Of course, dams present a complete barrior to upstream migration, unless fish ladders are in place, and even fish ladders are not 100 percent effective, as many fish are unable to locate the ladders. Salmon populations upstream of Grand Coulee Dam, which does not have fish ladders, disappeared, except for the freshwater varieties.

A fish ladder is a structure which allows fish to move past an obstacle such as a dam. Without fish ladders, fish would be stuck downstream of the obstacle, and this could potentially have a negative impact on the breeding cycles and lifestyle of the fish. So, It protects the fish in the environment, and helps animals that eat fish.
