Mercer County Reservoir

— Miami and Erie Canal Feeder —

Grand Lake St. Marys was constructed between 1837 and 1845
as a feeder reservoir for the Miami and Erie Canal. The
reservoir provided a constant source of water for the
canal through a feeder canal located at the eastern
embankment of the lake. At the western embankment of
the lake a spillway was constructed in 1843 south of
the site of Coldwater Creek as a control structure
for the lake. Following the Flood of 1913 a new spillway
was constructed in 1914 at Beaver Creek near this site
The spillway complex included a gatehouse that housed
the gate opening mechanisms. Two historic plaques
from that gatehouse are mounted on this monument. The
present spillway was constructed between 1996- 1997 as
a replacement for the 1914 spillway, and is 500 feet long
and 19.5 feet from the crest to the toe of the
spillway.
