Lon Hagler Reservoir is a no-wake reservoir near Loveland in Larimer County, popular with anglers, trail users, and archery enthusiasts. Located just outside of town, this compact body of water offers free fishing access and a 2.25-mile trail that loops around the entire reservoir. Mountain views frame the western horizon, and the relatively quiet atmosphere draws visitors looking for a low-key outdoor experience without the crowds of larger Front Range reservoirs.
Fishing at Lon Hagler Reservoir is the main attraction, with anglers targeting stocked trout and occasionally landing impressive catches, including fish reported at thirty-one inches. The reservoir is stocked with trout, and shore fishing is the most common approach, though the relatively shallow shoreline can make casting to deeper water challenging. Boat fishing is permitted under trolling-only, no-wake rules, which keeps the water calm for everyone. Anglers report that the fish are not heavily pressured compared to other nearby waters, making it a productive spot when conditions cooperate. Summer months see heavier fishing activity, and some visitors note the lake can feel over-fished during peak season.
Kayaking and stand-up paddleboarding on Lon Hagler Reservoir benefit from the no-wake restriction, which keeps the surface smooth and safe for human-powered watercraft. The calm conditions also make it suitable for beginner paddlers. Water skiing has been mentioned by visitors as well, though the no-wake rule and small size suggest this refers to the general area rather than motorized skiing on the reservoir itself. Wind can be a significant factor, with gusts reported reaching forty miles per hour on exposed days, so checking conditions before heading out is wise.
The free archery range at Lon Hagler Reservoir is a standout feature that sets it apart from typical fishing reservoirs. The range accommodates compound bows and includes a dedicated area for shooting broadheads, making it popular with hunters practicing before season. Multiple visitors specifically highlight the archery range as a reason to visit, even independent of the water activities.
The trail circling Lon Hagler Reservoir stretches 2.25 miles and serves runners, hikers, bikers, and dog walkers. The path is easy and mostly flat, making it accessible for families and pets on leash. Some sections can get muddy, particularly near the shoreline and after rain. The area around the reservoir has very few trees, so sun exposure is constant and sunscreen or a hat is strongly recommended during warmer months. Sunsets over the water are frequently praised by visitors.
Facilities at Lon Hagler Reservoir are minimal. Restroom options are limited to a pit toilet or portable restroom that visitors report is inconsistently maintained. There is no camping, no concession stand, and no store. Parking is available but the lot surface is rough with potholes and large holes, so driving carefully on approach is advisable. The reservoir is free to access, though a valid Colorado fishing license is required for angling and game wardens do check. Dogs are welcome on leash, and the open terrain provides good space for training and exercise. There is no potable water on site, so visitors should bring their own supply for themselves and their pets.
