The fall spawning rainbow trout were culled from the breeding stock at Boulder Fish Rearing Station. The fish are about 16 inches long and weigh an average of 3 pounds, although a few are about 22 inches long and weigh 6 to 7 pounds.
As breeding stock, the fish produce between 2.5 and 3 million eggs per year. The eggs are shipped to fish hatcheries around the state where they are raised and eventually stocked into public waters. When broodstock fish reach three to five years old they are beyond their peak spawning production and are released into lakes and rivers in the state for anglers to enjoy. Crystal and Granite Springs reservoirs receive some of the brood culls each year.
Ice is beginning to form on both of the reservoirs but is still unsafe and anglers are urged to use caution.
