Rifle Gap Reservoir is the big-water state park near Rifle

Of the three state parks clustered north of Rifle, Rifle Gap is the one built around open water. Its reservoir sits in a gap between hogback ridges, and on a warm day you will see motorboats, water skiers, paddlers, and swimmers sharing it.

The reservoir supports full-size boating, with a boat ramp on the north side near the campground. Fishing is popular here too, and the park also has campsites, picnic areas, and trails for the days you would rather stay on land.

One step matters before you put a boat in: it has to pass an aquatic nuisance species inspection. Colorado checks boats at the ramp to keep out invasive mussels and other pests that can ruin a water body and are nearly impossible to remove once they take hold. If inspectors find something, the boat does not launch until it is cleaned. This is routine, not a hassle aimed at you, and arriving with a clean, drained, dry boat makes it quick.

Entering the park takes a valid Colorado parks pass, either a daily vehicle pass or the annual Keep Colorado Wild Pass.
