Big Sandy Reservoir is a 2,500-acre lake located about 15 miles north of Farson, Wyoming at an elevation of 6,760 feet. The reservoir offers primitive camping and boat launching facilities with no fees required. Access is via a county road that may require 4-wheel drive vehicles during wet conditions.

The lake is situated in an open, high desert setting with views of distant mountains. Water levels can fluctuate seasonally, impacting shoreline conditions. Paddlers should be prepared for potentially muddy shores and cloudy water. Strong winds are common in this exposed area and can create challenging paddling conditions.

Wildlife viewing opportunities include wild horses that occasionally visit the lakeshore, as well as pronghorn antelope on the surrounding plains. Birdwatching is also popular. Fish species in the reservoir include brown trout, cutthroat trout, and catfish.

Facilities are limited to vault toilets and some picnic tables/fire rings. There is no potable water available. Cell phone coverage is very limited. The area sees relatively low use, offering a sense of solitude, especially on weekdays.

Paddlers should be aware that the lake can have significant mosquito and other insect activity, particularly in calm conditions. Early mornings or breezy days may provide the most comfortable paddling experience. Given the remote location and lack of on-site management, paddlers should be self-sufficient and prepared for emergencies.

The Bureau of Reclamation manages recreation at Big Sandy Reservoir. While no specific paddling restrictions are mentioned, users are advised that all activities are undertaken at their own risk due to the primitive nature of the site.
