About the Reservoir
Boat Ramps and Docks
Boats may be launched at either of our two boat ramps.
- The North Boat Ramps, located on the northwest side of the reservoir, have eight launch lanes and four courtesy docks.
- South Boat Ramp, located on the southeast side of the reservoir, has two launch lanes and one courtesy dock.
- The courtesy docks are available seasonally and will be removed when ice starts to form on the lake.
The reservoir can be quite busy during the summer season and is divided into use zones.
The main body of the reservoir is the Power Zone. This area is for general boating and water skiing and has a counter clockwise direction of travel.
There are two large No Wake Zones at the southwest and southeast ends of the reservoir.
These areas are great for fishing, canoeing or just taking a break. During times of peak use, the reservoir may reach boating capacity. When boating capacity is reached, rangers at the boat dock will not allow boats to launch until a vessel has left the reservoir.
- The reservoir closes to boating December 1 to March 1 AND ice off. During the off-season, many of the aids to navigation are not in place.
- Please recognize that not all hazards may be marked, so always use caution when boating. With the fluctuation of stream flows, boaters should always watch carefully for floating debris in the reservoir.
- Motorized vessels and sailing vessels are only permitted on the main reservoir.
- The Gravels Ponds and all other bodies of water are strictly for non-motorized use.
- All Colorado Boating Statutes and Regulations are enforced. Copies of current boating regulations are available at the entrance station, park office.
