TRANSCRIPT OF AUDIO
From the Cumberland Gap to the Atlantic Ocean, this is Virginia Water Radio for the week of October 15, 2018.
SOUND - ~ 13 sec
Those were sounds of rainfall, an overflowing storm sewer, and a stream cascading into the New River at Radford, Va., on October 11, 2018, as that river was rising due to heavy rain from the remnants of Hurricane Michael and an approaching cold front. Those weather systems resulted in flooding in rivers and streams across the southern half of Virginia. The arrival of that rainfall and high water made this a good week to revisit a 2011 episode on the High Water Mark program coordinated by the National Weather Service and the U.S. Geological Survey.
Have a listen for about two minutes to part of the October 18, 2011, ceremony unveiling the high water mark sign for the New River at Radford. The comments are by Richard Harshberger, vice-mayor of the City of Radford; Anthony Phillips, who donated the Radford high-water marker; Dave Wert, meteorologist-in-charge at the National Weather Service’s Blacksburg Forecast Office; and Peter Corrigan, hydrologist at the Blacksburg office.
VOICES - ~ 1 min/53 sec.
[Richard Harshberger:] “Good morning. On behalf of the City of Radford, I’m honored and pleased to receive the second high-water-mark sign in the Commonwealth.”
[Anthony Phillips:] “The actual hurricane that produced these record floods developed down in the Caribbean on August 5th, 1940..... After it made landfall, it really slowed down, and actually spent three days over the southern Appalachians. And it started raining here in Virginia on August 13, and of course this flood occurred on August 14. And it spent three or four days over land, just producing copious amounts of rainfall. The water that produced this record rainfall actually occurred over Floyd in the Little River, which runs into the New upstream...they got 17 inches in two days in Floyd County.”
[Dave Wert:] “It’s flooding, and flash flooding specifically, that produces overwhelmingly the most number of deaths annually across the nation.... Just a simple Category 1 hurricane coming in on the border of Georgia and South Carolina—a lot of people think that Category 1, Category 2, Category 3, the stronger the storm, the more the potential impact. That’s not the case, especially when it comes to a flash flood or flooding situation.”
[Peter Corrigan:] “But, you know, one thing that we’ve noticed in the past five years, 10 years, in increase in massive flooding. Pennsylvania, Nashville, Tennessee, Atlanta, Georgia—floods that have greatly eclipsed past records. So, you know, we’re looking at, this is the highest we’ve ever achieved [at Radford] but there’s no reason it can’t be exceeded, even by significant amounts. Iowa broke a record by 10 feet just recently as 2008, a river that had 100 years of records. So, this is the highest it’s reached, but it’s not to say it couldn’t reach higher. And we hope not.”
As you heard, the record high level for the New River at Radford was produced by rainfall from an August 1940, category 1 hurricane that came ashore along the Georgia-South Carolina border. That hurricane’s rainfall raised the river level to almost 36 feet, or 22 feet above flood stage. That compares to the river’s October 12, 2018, crest at about 23 feet, or 9 feet above flood stage, following the impacts of Hurricane Michael.
The Radford high-water marker is one of three so far in Virginia, joining ones in Montgomery County and in the City of Franklin. About 130 markers are in place nationwide. Silently recalling dramatic histories, the signs are all intended to raise citizens’ awareness of an area’s flooding history and encourage their preparedness for storms and floods yet to come.

EXTRA FACTS ABOUT THE HIGH WATER MARK SIGN PROGRAM
The following was taken from the National Weather Service (NWS)/Office of Climate, Water, and Weather Services, “High Water Signs,” online at http://www.nws.noaa.gov/os/water/high_water/intro.shtml, as of 10-11-18.
“Severe flooding is part of the history of many communities in the southeast United States. Despite this reality, many residents are not fully aware of the flood potential in their area.
“To help raise awareness of flood risk, NWS began a project in 2006 to install High Water Mark signs in prominent locations within communities that have experienced severe flooding. Locations are selected based more on visibility than location of the flood. For example, a sign might be placed on the wall of a building downtown rather than near a rarely visited riverbank.
“Service Hydrologists from local NWS offices coordinate with emergency management and other local officials to select the best locations for the signs. The U.S. Geological Survey is involved as well, providing historical data and aiding with the surveying of high water mark signs in their districts.
“The first sign was unveiled in Rome, Ga., on March 21, 2007, during Flood Safety Awareness Week. Rome’s record flood occurred on April 1, 1886, when the Oostanaula River rose to a stage of 40.3 feet, inundating some parts of downtown Rome with more than 20 feet of water. The downtown area was so severely damaged that the city opted to fill in much of it, so that street level of present-day downtown Rome is what used to be the second floor. Even so, the high water mark was more than four feet above the ground. The sign was installed on the side of the Rome Area History Museum building.”
