Southwest Colorado boat ramps reopen as low snowpack shortens season

The first Southwest Region launch is back on at Navajo State Park, but this is not summer boating yet. Low snowpack has already shortened the playbook, and the next real decision is less about whether to launch than whether the reservoir, the wind and the water temperature are ready for you.

Navajo became the region’s first boat ramp to open this season, with weekend-only service from March 13 through April 12 before daily hours began April 14, from 8 a.m. to 4 p.m. Colorado Parks and Wildlife lists the Navajo ramp season as March 1 to November 30, with hours shifting with staffing. The ramp itself is one of the longest in Colorado, extending 110 feet down to the river channel. That matters at a reservoir where the Colorado side is expected to run low, even though a wet fall in 2025 helped preserve a quality experience and left some debris in the water that boaters still need to watch for.

Navajo is the kind of place people drive for, not just because it is about 35 miles southwest of Pagosa Springs and 45 miles southeast of Durango, but because the reservoir stretches 20 miles south into New Mexico. It is also the clearest example of why “open” does not mean “easy.” Colorado Parks and Wildlife classifies water under 70 degrees as cold water for most of the year, and temperatures around 40 degrees can turn a short swim into an emergency. Cold-water shock can drown even strong, experienced swimmers, and CPW says most swimming, paddleboarding and kayaking deaths happen when people are not wearing life jackets.

Wind is the other spring trap. On open reservoirs, a calm launch can turn ugly fast, so checking hourly wind forecasts before putting in is not optional. CPW has teamed with the National Weather Service before at Lake Pueblo to warn visitors about sudden wind and storms, and the same lesson applies across the Southwest Region: if the forecast looks sloppy, the water usually is.

The other piece of early-season boating is paperwork, and Colorado is strict about it. All trailered and motorized watercraft must be professionally inspected before entering the water, and motorboats and sailboats need an aquatic nuisance species stamp before launching. CPW also keeps pushing clean, drain and dry practices because invasive species can damage lakes, reservoirs, rivers and streams, along with the state’s economy, public health, property values and parks.

Sweitzer Lake State Park gives boaters another early option, especially for day-use trips near Delta. The 137-surface-acre reservoir opens its boat ramp today, April 15, with hours from 8 a.m. to 4:30 p.m. seven days a week. That is the season in miniature across southwest Colorado right now: access is back, but the best launches will come early, with a life jacket on and one eye on the weather.
