New Flood Gauge in Rodanthe Being Installed
to Help Determine Flooding Impacts
By JOY CRIST
new flood gauge is being installed at the Emergency Ferry Dock in
Rodanthe, per a recent announcement by North Carolina Emergency
The new gauge will join a network of more than 560 strategically
positioned rain and stream gauges across the state that measure
rainfall and water levels in order to warn first responders and
residents who live near flood-prone areas.
As the backbone of the state’s Flood Inundation Mapping and Alert
Network (FIMAN), the gauges provide real-time data that is used to
formulate forecasts, issue alerts, and convey the anticipated flood
impact to buildings and infrastructure. The data collected by the
NCEM is provided to federal agencies and is available through NOAA and
the National Weather Service.
FIMAN can show precisely which buildings and homes will flood when
local rivers or streams reach certain flood levels. During Hurricane
Matthew in 2016, this capability was used to direct efficient and
appropriate evacuations and resources.
Currently, three flood gauges are stationed along Hatteras and Ocracoke
islands, which includes a gauge at the NCCAT campus in Ocracoke, a
gauge at the U.S. Coast Guard Station in Hatteras, and a gauge at the
Oregon Inlet Marina.
The new gauge in Rodanthe is part of 13 more devices that will join
this state network, and help alert local communities to dangerous
“Time and again over the last several years, we’ve used data from these
flood gauges to warn residents and communities about dangerous flood
conditions,” said State Emergency Management Director Mike Sprayberry.
Much of the flood data is available in real time through the ReadyNC
mobile app developed by NCEM. App users can click on Flood Gauges to
check the current status of sounds, creeks, and rivers nearby to see if
the water level is at normal levels or minor, moderate or major flood
“Adding new gauges in these areas will help communities be more aware
and prepared for flooding, and will allow for better warning when
floods are coming,” said State Emergency Management Director Mike
Sprayberry. “FIMAN is a powerful tool that helps us very
accurately define what areas will be affected by flood waters, so
emergency managers and local officials can take the appropriate actions
to keep people safe.”
