The S-193 Taylor Creek Lock in Okeechobee, FL, is one of the largest locks to provide access in and out of Lake Okeechobee. Lake Okeechobee is the largest freshwater lake in the state of Florida and is the seventh largest in the United States. Lake Okeechobee covers approximately 730 square miles (1890 square km). Taylor Creek is located at the northernmost tip of Lake Okeechobee. 

The S-193 Taylor Creek lock was constructed in 1936. The full length of the lock is 230 ft (70 m). The current width of the lock is 50 ft (15 m) and the lock gates are 32 ft (10 m) high. 

The South Florida Water Management District (SFWMD) is the managing authority for the S-193 lock. In 2012, SFWMD determined that the erosion on the submerged portions of the lock walls were in need of repair. After nearly 70 years of operation, the concrete beneath the surface of the water had been eroded by the sulfates and other elements in the water of Lake Okeechobee.

The renovation contract called for the removal of 3 in. (75 mm) of existing concrete from the floors and for a 12 ft (4 m) height at the walls. The concrete was removed using high-pressure water-blasting equipment. After this process, dowels were inserted into the concrete at 24 in. (600 mm) on center. A 6 x 6 in. (150 x 150 mm) welded wire mesh was attached to the concrete dowels prior to the application of 4.5 in. (115 mm) of shotcrete material to the walls. The wall concrete mixture was designed for an 8000 psi (55 MPa) wet-mix shotcrete with granite coarse aggregate. The removed concrete on the floor was replaced with 4.5 in. (115 mm) of 6000 psi (41 MPa) concrete.
