Lake Ontario Flooding

flooding along Lake Ontario with street under water

Due to significant rain in early May 2017, the Lake Ontario coastline rose to the highest levels in 20 years. Governor Cuomo declared a state of emergency (link leaves DEC website) for the affect communities along the shoreline on May 2. He deployed the National Guard, requested additional water release through the Moses-Saunders dam to lower Lake Ontario water levels, and authorized DEC to issue emergency permits.

As part of the Lake Ontario Rapid Response Team, DEC is deploying a team of experienced coastal engineers to Lake Ontario to work with property owners to address erosion, conduct site visits, meet with owners, and offer technical guidance. The team will rapidly review all emergency permit applications received. DEC's engineers stand ready to work with property owners so that protective structures can be repaired and homeowners can take appropriate actions expeditiously.

DEC, along with the Division of Homeland Security and Emergency Services and the Department of Financial Services, will staff NYS Emergency Response Mobile Command Centers which will be stationed in the flooding area the week of May 15. See the Governor's press release for locations.
