Long Description:The Court Street Dam functions as a water-control structure for the
lower Genesee River to regulate water levels in the nearby Erie
Barge Canal during navigation season and to furnish water for the
Rochester Gas and Electric hydroelectric plant at the west end of
the dam. Constructed in two phases in 1917 and 1926, the facility
consists of four sector gates, separated by two concrete operating
piers and a center mass-concrete pier and bounded by two concrete
abutments. The sector gates are pie-shaped and hinged at their
downstream end; they float up into position under hydraulic
pressure. Through a series of interior valves and weir tubes
located in the operating piers, the internal hydraulic pressures
can be increased to lift the gates for water retention or can be
decreased to lower the gates to release water downriver. This type
of gate was first built in the Chicago area for a facility on the
Chicago Drainage Canal at Lockport, IL. The original design has
been credited to Mr. E.L. Cooley (Cooman 1927), and it is believed
there are only a couple of other similar facilities in this
country.
