Cattail Bay Boat Ramp

Cattail Bay offers a boat ramp on Lake Oahe with a large gravel parking area, vault toilets, and a portable dock.

The existing single-lane ramp (241 feet long, 17 feet wide) experiences heavy congestion during peak fishing season, with an average of over 20,000 vehicle visits annually, making it a popular but potentially crowded access point.

A widening project was planned to create a two-lane ramp to improve launching efficiency and reduce bottlenecks.
