DOW TOGS 3.1.5 – GUIDANCE FOR DAM HAZARD CLASSIFICATION
New York State uses a dam downstream hazard classification
system similar to that of many states and federal agencies. The
following three classification levels are used in New York. They
are listed in order of increasingly adverse consequences from a
dam failure.
These classification levels build on each other, with the higher
levels adding to the consequences of the lower levels. These
downstream hazard classifications are defined in 6 NYCRR Subpart
673.5(b), and are repeated here for reference.
(1) Class "A" or "Low Hazard" dam: A dam failure is unlikely to
result in damage to anything more than isolated or unoccupied
buildings, undeveloped lands, minor roads such as town or county
roads; is unlikely to result in the interruption of important
utilities, including water supply, sewage treatment, fuel,
power, cable or telephone infrastructure; and/or is otherwise
unlikely to pose the threat of personal injury, substantial
economic loss or substantial environmental damage.
(2) Class "B" or "Intermediate Hazard" dam: A dam failure may
result in damage to isolated homes, main highways, and minor
railroads; may result in the interruption of important
utilities, including water supply, sewage treatment, fuel,
power, cable or
telephone infrastructure; and/or is otherwise likely to pose the
threat of personal injury and/or substantial economic loss or
substantial environmental damage. Loss of human life is not
expected.
(3) Class "C" or "High Hazard" dam: A dam failure may result in
widespread or serious damage to home(s); damage to main
highways, industrial or commercial buildings, railroads, and/or
important utilities, including water supply, sewage treatment,
fuel, power, cable or telephone infrastructure; or substantial
environmental damage; such that the loss of human life or
widespread substantial economic loss is likely.
