Lake Nighthorse opens with limited spring access, daily hours coming soon

Lake Nighthorse’s spring window is narrow right now: nonmotorized boaters and swimmers can get on the water only Fridays through Sundays, from 9 a.m. to 4 p.m., until May 3. Daily operations are scheduled to start May 8, with motorized boating following on May 15, so this weekend is the kind of outing that works best if you want a quiet paddle, a swim session or a short family day near town rather than a full summer launch day.

The timing matters because Lake Nighthorse sits about 2 miles southwest of downtown Durango, close enough to be an easy day trip but far enough out to feel like a proper break from town. City spokesman Tom Sluis said the gradual rollout reflects the normal spring ramp-up. “Once the weather gets a bit warmer and demand increases, (Lake Nighthorse) opens up for additional days,” he said. For anyone deciding whether to make the drive now or wait, the answer is simple: if you want weekday access or a motorized boat run, this is not the weekend for it.

Getting there may take a little extra planning. The paved access road from the ticket booth down to the boat-ramp parking area is under construction during the 2026 season, and the city said the project will reduce available parking spaces through the summer. The work is being handled by the City of Durango and the Bureau of Reclamation, with grant funding and construction support from the Federal Highway Administration. Carpooling is already part of the practical reality for peak weekend hours, especially if you are hauling kayaks, heading to a swim window or trying to arrive late in the morning.

The lake’s rules also stay tight once you are on site. Recreation is limited to developed areas and land within 25 feet above the reservoir’s high-water line to protect cultural resources, and visitors receive rules brochures at the lake. The decontamination station, built in 2025 to keep invasive aquatic species out of the reservoir, is open around the clock for non-ballasted boats and runs Thursday through Monday for ballasted boats.

Lake Nighthorse’s draw is hard to miss. The 2023 season brought 98,117 visitors, up from 89,338 in 2022, and the season report linked part of that jump to new daily Wibit operations and reservations. Long before it became a warm-season hangout, the reservoir was part of the Animas-La Plata Project, authorized by Congress in 1968. Reclamation began construction in 2002, the lake began filling on May 4, 2009, and filled for the first time on June 29, 2011. At full pool, it stores 123,541 acre-feet at a maximum water-surface elevation of 6,882 feet.

Annual passes are available through the Durango Community Recreation Center, a useful detail for anyone who expects to keep coming back as the schedule opens up.
