New York State Flood Investigations

Science Center Objects

Flooding can be a serious problem in many parts of New York State. Information on floods and analyses of flood data are needed to aid in the design of bridges, culverts, dams, highways, and buildings, and for the prudent management of flood-prone areas. Documentation of floods and a more thorough understanding of flood hydrology and hydraulics will result in more effective management of flood plains and design of structures.

The New York Water Science Center (NYWSC) provides information on the magnitude and frequency of floods to agencies and individuals involved in flood-protection, planning, and design. The NYWSC also develops regional flood-frequency relations for streams in New York to allow flood-frequency determinations at locations without stream gages and conducts local site studies using hydrologic and hydraulic analyses.


New York Peak Flow Map

This Interactive Map identifies locations (depicted as orange dots) in New York State where the New York Water Science
Center has records of maximum recorded stages and discharges. Many of the locations have flood frequency statistics computed.
