TO:Emergency Management Officials, News Media,and Other Users

SUBJECT: River Forecast Services for the Nimishillen Creek in
North Industry Ohio will be modified effective July 10, 2017.

Effective Thursday Monday July 10, 2017 the National Weather Service
will change the official flood stage at the Nimishillen official
forecast point at North Industry. The minor, moderate, and major
flood stages will be changed from the current stages of 9.0, 10.0,
12.0 feet respectively to 10.0, 12.0, and 13.0 feet.

Minor flooding is defined as the point at which property is
inundated or a flooded roads cut off emergency access. Moderate
flooding is considered the stage at which numerous roads are
threatened or a few low lying properties become inundation. Major
flood stage is considered the point where flood waters cause major
property damage or extreme threat to life. Based on the impacts
associated with specific river stages, it is recommended that the
minor flood stage be raised to 10.0 feet, moderate flood stage to
12.0 feet, and the major flood stage to 13.0 feet.

It is necessary for the National Weather Service to periodically update
flood stages at river forecast points as changes, both natural
and manmade, occur over a watershed. These updates are needed to
ensure the best quality river forecasts and resulting warnings to
local communities. The NWS, Ohio River Forecast Center (OHRFC),
and Local and County Officials have supported the above
corrections.

The data and forecasts for is site can be found at:

Additional river forecasts can be found at: water.weather.gov/ahps/

The data for these sites are provided by our partner the USGS.
Without this critical data forecasts and warnings would not be possible.
