Boxelder Reservoir Number Three is one of Larimer County's newer fishing destinations, managed by Colorado Parks and Wildlife as part of the expanding network of state wildlife areas north of Fort Collins. Sitting at roughly 5,000 feet along the plains-to-foothills transition zone, this shallow prairie reservoir averages 5 to 10 feet deep with a muddy bottom, creating habitat suited to warmwater species like northern pike, bass, and panfish.
Fishing here rewards patience and technique over casual casting. Shore anglers will find the south bank most productive, while kayak anglers gain an advantage reaching submerged structure that holds fish throughout the reservoir. Pike fishing draws the most consistent reports of success, and experienced anglers working lures or dead bait along weed edges can connect with solid fish. Panfish and other species are present but catch rates run slow, so beginners may want to start at a more forgiving pond before tackling this water.
Facilities at Boxelder Reservoir Number Three are minimal but functional. A vault toilet stands near the access point, and a walking path circles the reservoir for those who want to scout shoreline or stretch their legs between casts. Parking is limited, so arriving early on weekends is a smart move. There is no boat ramp, but hand-launched kayaks, canoes, and float tubes are permitted under wakeless boating regulations. No swimming, picnic tables, or fire pits are available.
Dogs must remain on leash at all times, though visitors report that off-leash dogs are a frequent issue. The east side of the reservoir opens up to wider views of the surrounding plains and foothills. Boxelder Reservoir Number Three works best for anglers who enjoy quieter, less-developed waters where putting in extra effort pays off with diverse species and fewer crowds.
