In 1888 William G. Steel, considered the founder of Crater Lake National Park, made the first recorded attempts to stock Crater Lake. National Park Service researchers believe that before that time, Crater Lake contained no fish. William Steels motive for stocking the lake was probably to improve the lake's recreational value.
Around the turn of the century, a regular stocking program was begun. Stocking continued through the early part of the century until creel censuses showed that the fish were naturally reproducing. Six species were introduced to Crater Lake during this time. The last recorded stockings were silver salmon in 1937 and rainbow trout in 1941.
