The second set of falls, the Otter Creek Falls, is in the town of Middlebury, the site chosen in 1800 to be Vermont's original seat of higher education, Middlebury College. According to Around Middlebury, Otter Creek is the longest river in Vermont and was once an important "highway" through the western part of what is now the state.
In Addison County, Otter Creek passes through significant wetlands, in particular Cornwall Marsh, Little Otter Creek Marsh and the Brandon Swamp.
Because it is called a creek, the unusual situation of a river emptying into a creek occurs several times along its length. The source and mouth are separated by 68 miles (109 km) miles distance-the (approximate) additional 44 miles (71 km) are due to meandering.
