Cedar Shores provides public boat ramp access to Pontoon Creek and the Missouri River near Oacoma in Lyman County. This access point is designated for high water conditions, making it a valuable option when water levels are elevated. The site offers a practical launch point for kayakers, canoeists, and motorized boaters looking to access the Missouri River system in central South Dakota.
**What to Know Before You Go:** A South Dakota park entrance license is required to use this access point. The area features public boat ramps alongside several private marinas in the region, some of which may offer amenities like RV hookups and camping. Be aware that some private ramps can become difficult to use during low-water periods, so confirm conditions before your trip. As a high-water access site, Cedar Shores is most reliably usable when water levels are running above normal—check current water conditions on the Missouri River before launching.
