Chalk Cliffs Trout Rearing Unit
The mission of Chalk Cliffs Trout Rearing Unit is to provide catchable trout to waters throughout the Front Range and Eastern Plains of Colorado. Our stocking area reaches from Loveland to Trinidad, and out to the Kansas border.
“Catchable” trout refers to 10-inch-long trout that provide immediate recreation opportunities. We stock ponds and lakes that are open to the public. Chalk Cliffs produces about 700,000 ten-inch trout per year. Our stocking season starts in January and stays very busy from mid February until mid June, when the water temperatures in most waters get too warm to stock trout. We resume stocking in late September once waters cool down from summer temperatures, and continue through December.

Your Fishin’ Is Our Mission!
Colorado’s Fish Stocking Program
Since 1881, Colorado Parks & Wildlife fish hatcheries have been dedicated to improving the fish populations of our beautiful state. Today, CPW operates 19 hatcheries that breed, hatch, rear and stock over 90 million fish per year. Many of the fish produced are to enhance angling opportunities, while others serve a critical role in native species recovery efforts. Colorado fish hatcheries support our angling pastime, which contributes 2.4 billion dollars annually to our state's economy!
