One of the consequences when President Nixon signed the Lassen Volcanic Wilderness Act of1972 was the elimination of fish planting in two-thirds of the park. The area comprised the national park’s eastern section where the majority of the lakes are located.
One of the earliest known plantings was done prior to the creation of the park. In mid-July 1915, the first planting occurred through the efforts of San Francisco resident E.T. Niebling. The California Department of Fish and Game provided him with 5,000 small rainbow trout, which he planted in Juniper Lake. Beginning in 1927, the park, with the assistance of the Department of Fish and Game, began annual fish plantings in the majority of the lakes, that ceased at the conclusion of 1972.
