Nelson Lake, located in Oliver County near Center, North Dakota, offers a unique paddling experience as the state's only lake that maintains warm water year-round. Fed by the cooling system of the nearby Minnkota Power Plant, the lake never freezes over in winter, making it an exceptional destination for anglers but also creating distinctive paddling conditions. The 573-acre lake features approximately 13 miles of shoreline with depths averaging 16 feet and reaching 35 feet at its deepest point. The warm water temperatures foster an abundant largemouth bass fishery—considered among the best in North Dakota—along with populations of bluegill, white crappie, and northern pike. This fish-rich environment attracts diverse wildlife, including waterfowl and wading birds.

Paddlers can access Nelson Lake from public boat ramps and fishing piers maintained by the park district. The lake's warm water creates comfortable paddling conditions during spring and fall when other North Dakota waters may be uncomfortably cold. Summer paddling is popular, with the lake serving as a hub for family recreation including swimming, water skiing, and fishing alongside kayaking and canoeing. The lake's protected location 5 miles east and 3 miles south of Center provides some shelter from North Dakota's persistent winds, though paddlers should remain aware that open water conditions can still develop.

The relatively small size makes Nelson Lake suitable for paddlers of various skill levels, including families and beginners looking for a manageable adventure. The surrounding landscape offers scenic views of rolling prairie and agricultural land typical of central North Dakota. Primitive and developed camping facilities near the lake make it convenient for extended paddling trips, and the proximity to town allows easy access to supplies and services. Given the lake's popularity for multiple recreational activities, paddlers should expect company during peak summer months and weekends. The warm water and diverse amenities make Nelson Lake a distinctive paddling destination that stands out among North Dakota's many recreational waters.
