In 1832, the Cumberland and Oxford Canal opened, connecting Portland with Sebago Lake. A series of 27 locks lifted vessels from sea level at Casco Bay to Sebago Lake, above sea level. From there they traveled up the Songo River to Brandy Pond, then continued along the Chute River to Long Lake. As the company name indicates, the canal was originally planned to reach Oxford County, but instead terminated at Harrison. The town became a center for trade and transportation, with wharves and warehouses lining the shore.
