Prior to its construction, the canal path was surveyed by Jesse Williams, the canal engineer of Indiana. The state of Indiana already owned most of the land required for the canal. The canal was six feet deep and sixty feet wide. The northern section was from Peru to Broad Ripple, Indiana. It was surveyed primarily by William Goody. It was to use the Mississinewa River to Alexandria, Indiana, and then parallel the White River. Only Delaware and Madison counties saw significant progress, which consisted of limited digging. The eight fully completed miles were entirely within the Indianapolis section, continuing to parallel the White River. This section consisted of that were dug and watered, from Waverly, Indiana, to Broad Ripple, where the construction began. Because the land was undeveloped, construction between Broad Ripple and downtown Indianapolis was difficult. In the last half of the 19th century, various water companies used the section to power the water system in Indianapolis, which used purified well water and not canal water. In 1904 the Indianapolis Water Company finally took advantage of the partially built canal as a source for a purification plant. In the late 1960s, construction of Interstate 65 forced a section of the canal underground and by 1969 the IWC ceased using it as a source of power for its West Washington Street pumping station. Subsequently, In 1976 the IWC deeded the canal south of 16th Street to the city of Indianapolis. The city later undertook a project, beginning in 1985, to drain, rebuild, lower and then restore water to the remaining downtown section of the canal. Some of that portion of the Central Canal is now within White River State Park as well as running through the Indiana Government Center. The southern section was from Port Royal to Evansville. It was primarily surveyed by Francis Cleveland. The attempted were in Vanderburgh and Warrick counties. The Central Canal Towpath of Indianapolis follows along a portion of the completed. It runs from Broad Ripple to 30th Street near Riverside Park and goes by Butler University and the Indianapolis Museum of Art. Six different species of turtle populate the Indianapolis section, and are studied to see how urban environments affect wildlife. In 1971 the canal was designated by the American Water Works Association as an American Water Landmark.
