 Two canals cross the divide: The Chicago Sanitary and Ship Canal crosses the Chicago Portage and connects Lake Michigan to the Mississippi River watershed.
 The Erie Canal connects Lake Erie to the Hudson River watershed.
 Historically there were additional canals, e.g., the Ohio and Erie Canal, but most of these are no longer in operation.
The Chichester Canal is a navigable canal in England.
 It runs 4.5 mi from the sea at Birdham on Chichester Harbour to Chichester through two locks.

 When completed the canal could take ships of up to 100 tons.
 Dimensions were limited to 85 ft long 18 ft wide and a draft of up to 7 ft .

The Ashby-de-la-Zouch Canal is a 31 mi long canal in England which connected the mining district around Moira, just outside the town of Ashby-de-la-Zouch, with the Coventry Canal at Bedworth in Warwickshire.
 It was opened in 1804, and a number of tramways were constructed at its northern end, to service collieries.
 The canal was taken over by the Midland Railway in 1846, but remained profitable until the 1890s, after which it steadily declined.
 Around 9 mi passed through the Leicestershire coal field, and was heavily affected by subsidence, with the result that this section from Moira, southwards to Snarestone, was progressively closed in 1944, 1957 and 1966, leaving 22 mi of navigable canal.
The Stainforth and Keadby Canal is a navigable canal in South Yorkshire and Lincolnshire, England.
 It connects the River Don Navigation at Bramwith to the River Trent at Keadby, by way of Stainforth, Thorne and Ealand, near Crowle.
 It opened in 1802, passed into the control of the River Don Navigation in 1849, and within a year was controlled by the first of several railway companies.
 It became part of the Sheffield and South Yorkshire Navigation, an attempt to remove several canals from railway control, in 1895.
 There were plans to upgrade it to take larger barges and to improve the port facilities at Keadby, but the completion of the New Junction Canal in 1905 made this unnecessary, as Goole could easily be reached and was already a thriving port.
