Cottonwood Lake in Williams County, North Dakota, offers paddlers a 306-acre natural lake experience in the northwestern region of the state. Located approximately 1 mile east and 0.5 miles north of Alamo, this fishery provides relatively straightforward access via a paved public boat ramp with a fishing pier on the south side of the lake. The lake reaches a maximum depth of about 13 feet, creating a shallow prairie environment that paddlers should navigate with appropriate caution, particularly during low water periods.

Cottonwood Lake has experienced periodic winterkills that significantly impact fish populations, most recently with a likely winterkill in 2023. This shallow nature and history of winter oxygen depletion means water quality can vary seasonally. The surrounding landscape consists of meadows, wetlands, and agricultural land, providing paddlers with expansive prairie views and open-water conditions. The relatively small size makes the lake manageable for a half-day outing, though paddlers should be prepared for limited wind protection on this open water body.

Wildlife viewing opportunities include waterfowl and shorebirds typical of North Dakota prairie wetlands. Access to the lake is straightforward, with the boat ramp providing suitable launch capabilities for canoes, kayaks, and small motorized watercraft. When water levels are adequate, the lake offers a peaceful paddling environment away from major population centers, though recreational use can be moderate during peak fishing seasons.

Paddlers should be aware that fishing regulations prohibit the use of live baitfish on Cottonwood Lake, which may affect other recreational use patterns. The lake's northern pike and yellow perch populations fluctuate based on environmental conditions. Given the shallow depth and agricultural watershed, paddlers may encounter variable water clarity and should plan trips during stable water conditions for the best experience.
