UPDATE: With the Colorado River flowing below 9,000 cfs, the City of Grand Junction plans to switch from a red to a yellow flag on Friday, June 21 at the Las Colonias River Park. Under a yellow flag, visitors are welcome to enjoy the channel with innertubes and other watercraft. Remember that the River Park channel is NOT a continuous loop and users must exit at the end behind the Amphitheater or risk ending up in a side channel or the main section of the Colorado River. Life jackets are always recommended for those enjoying recreation in the River Park and on the Colorado River.
The flags used to notify the public about hazard levels are located near the east and west ends of the River Park. A yellow flag signifies a medium hazard warning and while innertubes are acceptable, visitors should still exercise caution using the park. A red flag indicates a high hazard warning and only experienced river users should use the park with strong caution. Users are asked to watch for an update to a red flag next week as the winter snow melt continues to increase river flow and water levels.
Life jackets are strongly recommended for all visitors of the River Park. Life jackets, through the Save-A-Life Life Jacket Program, are available free of charge at each kiosk on the east and west ends of the park. No lifeguards are on duty at the River Park and guardians are responsible for all youth. City River Park hosts are present at busier times to provide educational materials and to help visitors have a positive experience.
The River Park at Las Colonias includes a lengthy and accessible water channel, a standing wave water features, a beach and wading areas. These amenities are accessible to a wide range of ages, ability, and experience levels. There is also a boat ramp on the east side of Las Colonias Park for boats to enter and exit the Colorado River.
Each summer when river flows drop below 810 cubic feet per second (CSF) the main channel of the River Park is cut off with the placement of sandbags. While the River Park remains open, due to the lower water levels, the experience is different for users of the park. The water flow in the channel is closed to protect the habitat for the four endangered fish species in the Colorado River. The River Park channel was developed as an ecological enhancement to create additional aquatic and riparian areas and recreation was a secondary factor. Learn more about the River Park.
