Although it is a small community, Lowell is part of the Chicago metropolitan area, that is, it is classified as a suburb of Chicago, due to its being only about 40 miles away from the Chicago Loop.
According to the United States Census Bureau, the town has a total area of 4.2 square miles (10.8 km²), of which, 4.1 square miles (10.6 km²) of it is land and 0.1 square miles (0.2 km²) of it (1.92%) is water.
Located five miles outside the Great Lakes Basin, Lowell sought permission to pipe in lake water to replace city water drawn from its high fluoride deep wells. However, diversion of water out of the Great Lakes requires the approval of the Great Lakes Commission, which includes representatives of all the US states and Canadian provinces that border on the lakes. Lowell's request was turned down in 1991.
Lowell lies on the Valparaiso Moraine, almost on the Kankakee Outwash Plain. The town also lies near the St. Lawrence Seaway Divide.
