THE FIELD GUIDE

# A closed boat ramp can mean several different things

Distinguish trailer-launch closures, paddlecraft access, swimming limits and water-quality advisories before a Colorado lake visit.

Reviewed Oct 21, 2026 · Colorado Parks

## Read the permitted launch method

At Rifle Gap, low water closed the ramp to motorized boat access for the rest of the 2026 season, while hand-launched kayaks, canoes and paddleboards remain permitted. Crawford also distinguishes closed ramps from hand-launched human-powered craft. These notices concern particular methods of access. Check the exact language for your boat rather than treating a map marker or an activity badge as permission to launch.

## Do not assume every lake makes the same exception

Barr Lake's notice closes all boating, explicitly including hand-launched paddlecraft, and directs people and pets to avoid the water because of toxic algae. Boyd Lake's low-water notice instead permits hand-launched kayaks and paddleboards and swimming. A paddleboard exception at one reservoir says nothing about another reservoir. Read the water-quality notice as well as the ramp notice, and follow the current managing-agency instructions.

## A beach closure has its own boundary

Ridgway's Dutch Charlie swim beach is closed and swimming is prohibited in that beach area. The same notice discusses paddlecraft, boating and fishing elsewhere on the reservoir separately. Ridgway also has a November 1–March 31 motorized-boating restriction. Keep the beach, boating season and individual launch location distinct when planning a visit; a partial closure should not become a claim that the entire park is closed or that other activities are safe.

## Account for inspections and the return trip

Lake Pueblo requires boats to launch and load during inspection-station hours; gates close when the stations close. Weather can shorten those hours. At Mancos, hand launching remains possible during the ramp closure, but motorized craft still require inspection. Check both the access method and the inspection arrangement before departure, and leave enough time to retrieve the boat within the official operating window.
