Lake Selmac in Josephine County offers a 300-acre paddling destination with two boat ramps providing easy water access. The lake features multiple developed access points, including Keller's Landing and facilities along South Shore Drive.

Paddlers should be aware of potential water quality issues. The lake can experience cyanobacterial (harmful algae) blooms, particularly in warmer months. The water tends to be murky with some pond weeds present, and the shoreline can be muddy in places. During blooms, paddlers should avoid creating excessive spray and limit high-speed water activities.

The lake environment supports diverse wildlife, making it an excellent destination for bird watching. Canada geese are frequently present along the shoreline. Multiple docks around the lake provide alternative launching points, though some areas have significant aquatic vegetation.

Facilities include multiple campgrounds along the shoreline (Osprey, Eagle, Heron, and Teal loops), offering both RV and tent camping options. Day-use areas with picnic shelters are available, and the park requires a Josephine County Parks day use fee.

The lake is most easily accessed from I-5 Exit 55, traveling south on Highway 199 for approximately 22.7 miles, then turning left on Lakeshore Drive and continuing 3 miles to the main park entrance. The location is roughly 24.5 miles from Grants Pass.

Lake Selmac is suitable for beginner paddlers, as demonstrated by positive experiences from first-time kayakers. The relatively small size of the lake makes it manageable for novice paddlers while providing enough space for extended paddling sessions. The lake is typically calm, though wind conditions can vary throughout the day.

Operating hours are from sunrise to sunset, and the lake supports multiple recreational activities including fishing and sailing, which paddlers should share the water with.
