Harding Lake is a large freshwater lake located about 45 miles south of Fairbanks, Alaska. The lake spans nearly 3 miles at its widest point and reaches depths of up to 140 feet. Access is via the Richardson Highway, turning east at mile 321.5 onto Harding Drive.

The lake is home to Harding Lake State Recreation Area, which provides a boat launch facility for paddlers. A canal from the launch leads to the main body of the lake. The recreation area offers over 90 campsites, picnic areas, and hiking trails, making it convenient for multi-day paddling trips.

Harding Lake is surrounded by spruce and birch forests, with views of the Alaska Range visible on the horizon. The lake is fed by hillside runoff, springs, and two inlets. Large icebergs can sometimes be found in the lake, creating a unique paddling environment.

Wildlife viewing opportunities include the chance to spot harbor seals and black bears. The lake supports a variety of fish species, including Arctic char, lake trout, and burbot. Anglers should check current fishing regulations before casting a line.

Water temperatures in Harding Lake remain cold year-round due to its depth and glacial influences. Paddlers should be prepared for very cold water conditions even during summer months. While the lake can accommodate motorized boats and jet skis, its size allows for peaceful paddling experiences as well.

The lake was named after President Warren G. Harding, who visited the area shortly before his death in 1923. Originally known as Salchaket Lake, it has been a recreation destination for decades, with the state park established in 1967.

Paddlers should be aware that weather conditions can change rapidly. The lake's location in Interior Alaska means summer days can be long, potentially allowing for extended paddling hours. However, proper safety precautions, including carrying appropriate gear for cold water immersion, are essential year-round.
