Purchase a reproduction of this item on


William H. Rowe and a colleague clear the trout breeding pools at the Clear Spring Trout Ponds. Breeding pools stretched on either side of the hatchery building for over one mile. The pools were cleaned every other day to fight fungus and parasites. Traps were set along the side to catch predators such as heron, kingfishers, and rats.

The "Portland Evening Express", September 3, 1924 issue included an article "How Would You Like to Cast a Fly Into a Five Acre Pond Which for a Certainty Contains 20,000 Trout?"
