Rathbun Lake, located in south-central Iowa, is one of the state's largest lakes, covering over 11,000 acres. Known as "Iowa's Ocean," it offers paddlers expansive waters to explore along its 155 miles of shoreline. The lake's picturesque setting features rolling hills and timbered landscapes of the Chariton River Valley.

Paddlers can access the lake via multiple boat ramps located throughout the various parks surrounding Rathbun. The lake's calm waters make it suitable for beginners, while its size provides ample opportunity for longer excursions. Canoes and kayaks share the lake with motorized boats, so paddlers should be aware of boat traffic, especially during peak summer months.

Wildlife viewing is a highlight of paddling Rathbun Lake. Bald eagles, Canada geese, and wild turkeys are commonly spotted. White-tailed deer can often be seen along the shoreline. The lake is also known for its fishing, with crappie, walleye, channel catfish, and bass being popular catches.

Facilities for paddlers include multiple campgrounds around the lake, many offering electric hookups and amenities such as showers, toilets, and drinking water. Some campsites are waterfront, providing easy lake access. Two marinas, one at each end of the lake, offer supplies and services.

The lake is open year-round, but the main recreation season runs from May through September. Spring and fall can offer quieter paddling experiences with opportunities for wildlife viewing. Summer is busiest, with warmer water temperatures ideal for combining paddling with swimming.

Paddlers should be aware of the potential for strong winds on this large lake. It's also important to avoid the designated swimming beaches and the whirlpool area near the Rathbun Dam's control tower. As with any large body of water, weather conditions can change quickly, so paddlers should check forecasts and be prepared.
