Inscription. The Florence Canal resulted from a desire to tame the shallow and craggy Muscle Shoals. In 1830, amid urgings for a navigable solution, James Kerney of the Board of Engineers for Internal Improvements completed plans for a thirty-five-mile canal through the Muscle Shoals. More than six hundred men, including enslaved laborers hired from the local plantation owners, worked on the project. The canal opened for operations in July 1837, but with unsatisfactory results. The Shoals, leaving the little Muscle Shoals and Elk River Shoals unnavigable. Additionally, canal commissioners had failed to construct culverts diverting water flow from adjoining tributaries, which gradually led to sediment buildup and left the canals useless.

As part of a renewed motivation to extend national trade routes via river travel, the United States Army Corps of Engineers began construction another canal in 1875. After nearly two decades of work, several changes in leadership, and slow progress altogether, Goerge Washington Goethals and his men completed the job on November 8, 1890. The finished project was a sixteen-mile segment of three individual

canals forming a single passage. A one-and-a-half-mile canal with two locks bypassed the Elk River Shoals. Further along, a much larger fourteen-mile canal with nine locks was cut through the Big Muscle Shoals. Engineers completed the final canal by dredging a channel through the Little Muscle Shoals and building two wing dams along either side other constrict water flow. The resulting canal system fueled industrial growth in the Shoals region.
