Portage Canal

About this property

The Portage Canal was built to connect the Fox River and Wisconsin River at Portage, Wisconsin along the Fox-Wisconsin Waterway. For a time, it completed a route from the north Atlantic Ocean, through the St. Lawrence Seaway and down the Mississippi River to the Gulf of Mexico, and back to the Atlantic. Numerous attempts were made to build the thin Wisconsin-Fox connection through the marshy land, beginning in 1837 with the formation of the Portage Canal Company. Digging and hauling by hand through two and a half miles of muddy terrain, the project was quickly abandoned. A second project, started in 1849, managed to cut a path usable by canoe, but not viable for commerce. The final project, complete with locks to raise the water level of the Fox to that of the Wisconsin's, was not completed until 1876 by the Army Corps of Engineers. Unfortunately, by then, the railroads were quick on their way, followed soon thereafter by the automobile. The Portage Canal acquired a new steel gate and concrete lock in 1926 due to a rupture of the 1876 wooden gate and the quoin post of the west gate of the lock in April 1926. A local contractor, M.E. White Company of Chicago, was awarded the bid in August 1926. The firm completed the repairs of the lock and replaced the 1876 wooden gate under the supervision of the U.S. Army Corps of Engineers in Milwaukee. The 1926 Portage Canal Lock was the first steel and concrete lock on the Fox River. The subcontractor for the steel gate was the Lakeside Bridge and Steel Company of Wisconsin. During the re-construction process, the Engineers were faced with containing underground springs beneath the lock, which caused considerable delays. The White Construction Co. repaired the fallen wall and dismantled the remaining wall of the lock, which were re-laid and constructed according to the original configurations of the 1876 construction. The White Construction Company used 9,000 barrels of Portland cement to build the locks. The canal lock and new gate were completed in May 1928. The use of the canal as a major means of commerce lasted only a few decades, though pleasure craft, including steamboats, continued to ply the narrow waterway. In following years, the canal began to degrade through lack of upkeep. The canal was used until 1951 when the Fort Winnebago Lock was bulldozed in, and the Wisconsin River Locks were welded shut. The canal has undergone a significant restoration project to clean up and restore the canal, revitalizing it as a community asset. Beginning in 2020 and continuing into 2021, the DNR, in collaboration with the City of Portage, removed 30,000 cubic yards of contaminated sediment from the canal, addressing the legacy contamination from years of heavy industrial use, primarily heavy metals. Additionally, 1.3 million gallons of contaminated water were treated, seven storm sewers were extended to maintain stormwater management, and 40,000 tons of material were placed to construct the base for the foundation of an Ice Age Trail addition.
