With more than 8,000 miles of rivers and 2,000 lakes, Colorado has a lot to offer in the way of fishing, but Horsetooth Reservoir keeps rising to the top when it comes to the best spots to reel one in.
The reservoir sits in the foothills just west of Fort Collins, Colorado, and offers nearly 20 miles of shoreline. At six-and-a-half miles long and half a mile wide, the reservoir provides ample, shallow coves that make fishing smallmouth bass a favorite. The people at Buckhorn Ridge Outfitters state, “The scrappy smallmouth bass is a part of Colorado and it dominates the spring and summer shorelines of Horsetooth Reservoir … the coves of Horsetooth Reservoir become a smallmouth bass frenzy, rivaling the top lakes in the country!”
Fish & Regulations
In addition to smallmouth bass, you can expect to catch walleye, trout, splake, white bass, crappie, bluegill, and perch, according to the Horsetooth Reservoir Fish Survey and Management Data.
A quick search on fishidy.com or fishbrain.com will give you an even better picture of the fish they’re pulling out of the reservoir. Each of these sites has an interactive map, coordinates to favorite fishing holes, and pictures of catches—including a rainbow trout weighing in at over 20 pounds, and smallmouth bass coming in at just under three pounds. While the lake is open year round, spring and summer will bring you the biggest catches, with many of the best fishing done right from the shore. The cold slows down the fish as they scatter throughout the lake, leaving the coves where they’re so abundant in the warmer months.
And the fishing regulations at Horsetooth are pretty straight-forward.
|Fish||Daily Limit||Minimum Length|
|Bass (small and largemouth)||5||12”|
|Bass (white, striped, wipers)||10|
|Trout (rainbow, cut-bow, brown)||4FFF||None|
|Panfish (bluegill, crappie, sunfish)||20||None|
Note: Fishing from the dams isn’t allowed due to security concerns, and the reservoir isn’t open for ice fishing.
While fish is one of the healthiest foods you can eat, it’s also prone to be high in mercury in certain bodies of water because fish absorb mercury from the water around them. Since it’s toxic, it’s important to check mercury levels before consuming large portions.
Studies of the fish in Horsetooth have confirmed high levels of mercury in several types of fish, including some smallmouth bass, walleye, and wipers. This doesn’t mean you have to avoid all of them entirely, but you do need to know which are okay to eat, and which you should only eat limited amounts of.
Colorado Environmental Records provides the following recommendations.
Lures & Baits
When fishing near the dams, some people swear by live crawfish. They recommend throwing it out and letting it sink to the bottom and then jig it back in slowly, but that’s not what the 20 pounds trout came in on. That catch is attributed to a Matzuo Nano crank.
Anglers who’ve logged their catches into Fishbrain attribute their success to a variety of fishing lures and baits, including plastic tubes and worms, cranks, jigs, and spinners. Whichever baits you choose, if you plan on fishing from shore:
- Explore different areas, such as outcroppings, coves, and along the dam
- Alter your retrieval rate to see if fish bite better at a faster or slower rate
- Try your lures at different depths
This will help you determine where the fish are hiding

Named after Horsetooth Mountain, a summit at the southern end of the reservoir, construction on the reservoir began in 1946, and took three years to complete. In 1951 the reservoir began to hold water, with a capacity of 156,735 acre-feet of water and a maximum depth of 180 feet. The water in the reservoir comes primarily from the Colorado River headwaters beginning about 13 miles to the south through the Hansen Feeder Canal.
The reservoir is a supplementary source of water for Fort Collins, Greeley, and other nearby communities. It also provides water for irrigation.
Recreational boating, kayaking and canoeing have become popular during the summer months at Horsetooth and swimming is allowed at the designated beach and in some of the coves. Because of the shallow coves and rocky outcroppings, fishing has become highly popular from boats or from shore.
