The Marcus boat ramp provides easy access to the Ouachita River, a major waterway in Arkansas. The ramp is located in Felsenthal, Union County, with coordinates 33.06717447, -92.12979938.
The Ouachita River is a substantial headwater stream, spanning 548 miles with an average flow of over 27,000 cubic feet per second. It has a moderate gradient of 3 feet per mile, making it navigable for a variety of watercraft. Paddlers and boaters can expect moderate current and water levels that fluctuate with seasonal rainfall.
The boat ramp itself is a new concrete structure, recently improved by the Arkansas Game & Fish Commission, Montgomery County, and the U.S. Army Corps of Engineers. This access point provides a convenient entry point to the river for kayaks, canoes, and small motorized boats. Nearby recreation areas include the Upper Ouachita National Wildlife Refuge and the Ouachita-Black River Felsenthal Pool, offering additional opportunities for exploration, fishing, and camping along the Ouachita River.
