Salmon Ladder

“The Salmon is a well-known fish, inhabiting both salt and fresh waters, and ranking prominent among the food fishes of the United States and other countries. It generally attains a length of from three to four feet, and an average weight of from 12 to 30 pounds. In the fall the salmon ascends rivers for the purpose of spawning, and often encounters obstacles. In many streams they are assisted by structures known as ‘salmon ladders.’"—(Charles Leonard-Stuart, 1911)
