Old Lock 15 Boat Ramp offers a quiet access point to Holt Lake north of Tuscaloosa, featuring a single-lane paved launching ramp and paved parking area. A use fee is required for all visitors, and the location can get busy during summer months and holidays.

Basic amenities include pit toilets, making it a functional option for paddlers and anglers seeking a less-crowded gateway to the Black Warrior River system.
