The Lock and Dam Number 4 boat ramp provides access to the Arkansas River, a major waterway that flows 1,207 miles across Arkansas. The river here has an average gradient of 7.9 feet per mile and an average flow of over 51,000 cubic feet per second, making it an exciting and dynamic river for kayakers, canoeists, and motorized boaters.
The boat ramp is located in Altheimer, Jefferson County, Arkansas, and offers a convenient put-in point for exploring this section of the Arkansas River. The surrounding area provides additional recreation opportunities, including the Arkansas River - Pool 4 and Arkansas River - Pool 3 sections, which offer overnight camping, additional boat launches, and scenic natural landscapes. Boaters should be aware of the river's strong current and plan accordingly, but the Lock and Dam Number 4 boat ramp provides a reliable access point for accessing this impressive waterway.
