Corps of Engineers to inspect Mount Morris Dam

Published May 7, 2015
for the first time anyone can remember, the U.S. Army Corps of Engineers Buffalo District constructed a dirt coffer dam to divert the Genesee River through three open gates while they performed inspections inside six de-watered conduits, August 26, 2013.

Conduits are the tunnels beneath the dam through which the river passes. For this inspection, we were interested in the condition of the concrete conduits, the steel gates and all associated components.

As part of the U.S. Army Corps of Engineers (USACE) Dam Safety Inspection program, a multi-disciplinary team of engineers from the USACE Great Lakes and Ohio River Division will perform a 5-year periodic inspection of Mount Morris Dam, Mount Morris, NY on May 13. 

The USACE, Buffalo District would like to invite the media out to the dam May 13 from 11:30am to 1pm, to ask questions to the inspection team.

The USACE takes its dam safety responsibilities seriously and constantly monitors the Mount Morris Dam in order to detect potential weaknesses before they become a major concern and institutes a rigorous and thorough inspection process to reevaluate conditions and risks. As part of the process, recommendations for preventative maintenance and repair are provided and are included into routine operations and maintenance or as separately authorized and funded projects.

“As the Nation ages, so does its infrastructure,” said Steve Winslow, Manager of Mount Morris Dam.  “I am proud to say that the U.S. Army Corps of Engineers has routine processes in place to ensure that structures like Mount Morris Dam continue to function as they were designed and continue to minimize risk of disastrous flooding.”

Before the Mount Morris Dam was built, frequent and severe flood events caused major destruction in the city of Rochester and areas south of the city. Congress authorized the U.S. Army Corps of Engineers to build Mount Morris Dam in the Flood Control Act of 1944 at a cost of $24 million. Since it was built the dam has prevented over $2 billion worth of flood damages.

Mount Morris Dam is a massive concrete-gravity dam located on the Genesee River near the Village of Mount Morris in Livingston County, NY. The dam is situated deep in the Genesee River gorge near the northern end of Letchworth State Park and is approximately 245’ tall, 1,028’ across and is made up of over 750,000 cubic yards of concrete and has a storage capacity of nearly 302,000acre feet (98,000,000,000 gallons). The reservoir is able to hold water and serves to significantly reduce risk damages during catastrophic flooding events in areas downstream of the dam, including the City of Rochester.

In celebration of dam safety awareness month, May, USACE invites the public to learn more about the Mount Morris Dam by visiting the Mount Morris Dam and Recreation Area and the William B. Hoyt II Visitor Center. Admittance is free and ranger-guided tours inside the dam are offered daily. Call 585-658-4790 for more information.
