     Unlike other hatcheries around the state, the Como Bluff Hatchery was built at the turn of the century as a private facility.  The property was purchased by the Wyoming Game & Fish Department in 1939 after it became apparent the Red Buttes Hatchery south of Laramie would have to be abandoned due to lack of suitable water.  Because of the economic slowdown during World War II and the need to expand the original facility, the Como Bluff Hatchery was not put into full production until 1946.
     The hatchery was built here to take advantage of four natural springs, supplying 1,400 gallons of water per minute.  A variety of trout are raised, including Eagle Lake rainbow, fall-spawning rainbow, Kamloops rainbow, splake and cutthroat.  The hatchery also has an isolation facility where eggs and fish can be kept isolated from the main hatchery until they pass disease inspection.  Walleye eggs have been eyed there, hatched and then stocked back into the wild as “sac-fry.”
     You can fish for trout on nearby Diamond and East Allen Lakes.
