Boat Ramps at Grand Lk, Green Mtn, Lake Granby, Williams Fork, Wolford, and Shadow Mtn Are Closing for the Winter
Colorado Parks and Wildlife
As the fall season progresses and temperatures drop, Colorado Parks and Wildlife reminds boaters headed to the Grand Lake, Green Mountain, Lake Granby, Williams Fork, Wolford, and Shadow Mountain Reservoirs that they are closing to boating for the winter. Concurrently, aquatic invasive species watercraft inspection and decontamination stations at these reservoirs will stop running through the winter after their last days.

Here are the current hours and last dates for the reservoirs:

Grand Lake
Hours: 6 a.m.- 6 p.m.
East Inlet Ramp: Last Day, Nov 17

Green Mountain
Closed for the season on Sept 30.

Lake Granby
Hours: 6 a.m.- 6 p.m.
Sunset Ramp: Closed for the season on Oct 13.
Stillwater Ramp: Last Day, Dec 1

Williams Fork
Hours: 7 a.m.- 7 p.m.
Last Day: Oct 31

Last Day: Oct 15

Shadow Mountain
Hours: 6 a.m.- 6 p.m.
Green Ridge Ramp: Last Day, Oct. 31

Last days and hours are weather dependent.

Located between Kremmling and Estes Park, the reservoirs are popular among anglers and boaters for their kokanee salmon and their surrounding landscapes.

CPW encourages outdoor enthusiasts to take advantage of the last weeks of adventure at the lakes, but kindly ask that hours of operation and winter closures be respected.

While the weather is changing, the threat posed to Colorado waters by invasive species remains present. Per Colorado state law, watercraft requiring an aquatic nuisance species inspection may not launch outside the hours of operation, or when inspectors are not on duty. Boat ramp gates are physically closed when the inspection station is not open.

This year alone, CPW decontaminated 1,304 watercraft at the six reservoirs to reduce the biological risk that they posed. CPW and their partners continue to work on a daily basis to keep infested boats at bay from the state’s waters by providing inspection stations across Colorado. A stakeholders group is working collaboratively to protect state waters from harmful invaders through the inspection program and education efforts.

While Green Mountain Reservoir is considered suspect for the presence of quagga mussels, a containment watercraft inspection and decontamination program is currently being implemented. All boats leaving the reservoir are required to be inspected, and boats headed from Green Mountain Reservoir to any other location are required to be decontaminated prior to departure. Thus far, 2019 ANS sampling has not shown any presence of ANS species in Green Mountain Reservoir, and Invasive Species Specialists are optimistic that it will be delisted following the 2020 sampling season.

At waters without inspection stations, boaters are required to 'clean, drain and dry,' and should never launch without checking their vessels and following recommended procedures.
