New York Governor DeWitt Clinton, the
inspiration behind the canal system in his state, was on hand in Middletown to help turn
the first spade of earth on the Miami Canal as part of a ceremony on July 21, 1825. The
Ohio Canal Commission had carefully planned the construction in the months prior to that,
however.Canal commissioner Micajah Williams of Cincinnati planned the Miami Canal route
and supervised its construction. The commission hired talented surveyors, some of whom
were from Europe. Samuel Forrer (at right) surveyed much of the canal route through
Shelby County, Ohio.
Standard specifications called for the canal to be 28 feet wide at the bottom, 40 feet
in width at the top, with the water to be at least 4 feet deep. The tow path was 10 feet
wide, and the berm or 'heel' path (on the other side of the canal where a boat could tie
up) 5 feet. Banks were to be lined with clay. Locks on the Miami Canal were made of
limestone.
