Saint Marys Ohio has three water ways that run within a city block of each other.
The St. Marys River is the lowest of the
three water levels and provide the natural drainage. The Miami and Erie Canal,
which was constructed for
transportation, and with the aid of two canal locks, lowered that waterway
to an e medium middle elevation. The Saint Marys Ohio hydraulic canal was a water way
which split
from the Miami and Erie Canal prior Lock 12 and 13 with the Hydraulic
remaining at a high
elevation. Industry used to water from the Hydraulic to power water
wheels for factories with belt driven equipment prior to the expanded use of steam
boilers or the use of electric motors.
The rod iron fence on the north side of Spring St. in
downtown St. Marys Ohio avails that the hydraulic still flows under the building foundations.
