John Martin Reservoir State Park

Colorado Parks and Wildlife (CPW) warns visitors to avoid direct skin contact with water in the west boat ramp cove at John Martin Reservoir State Park due to blue-green algae toxin levels exceeding the recommended threshold. Routine water sampling detected toxin levels above the safety limit, prompting the advisory.

Low water levels at John Martin Reservoir State Park in Hasty, Colorado, have forced the closure of the west boat ramp, while the east ramp remains open. The closure is expected to last the rest of the season, though kayaks, canoes, and paddleboards can still launch from the west ramp. Colorado Parks and Wildlife emphasizes maintaining safe recreation access despite the challenge.
