...NEW FLOOD PREPAREDNESS TOOL AVAILABLE FOR THE MASON CITY
AREA...

A DYNAMIC...NEW ONLINE FLOOD PREPAREDNESS TOOL WHICH WILL HELP
EMERGENCY MANAGERS IMPROVE FLOOD WARNINGS AND RESPONSE HAS BEEN
DEVELOPED FOR THE WINNEBAGO RIVER AT MASON CITY...IOWA.

THE NATIONAL WEATHER SERVICE COLLABORATED WITH THE IOWA FLOOD
CENTER TO DEVELOP A LIBRARY OF FLOOD INUNDATION MAPS. THE FINAL
VERSION OF THESE FLOOD INUNDATION MAPS ARE THE CULMINATION OF A
PARTNERSHIP BETWEEN THE IOWA FLOOD CENTER /IFC/...THE CERRO GORDO
COUNTY EMERGENCY MANAGEMENT AGENCY...THE NOAA CENTRAL REGION
REGIONAL COLLABORATION TEAM AND THE NATIONAL WEATHER SERVICE
/NWS/. THIS CAPABILITY WILL HELP COMMUNICATE THE RESIDUAL FLOOD
RISKS FOR AREAS BEHIND THE CITY/S LEVEE AND THE ADDITIONAL
FLOODING FROM WILLOW CREEK...A TRIBUTARY TO THE WINNEBAGO.

BECAUSE THIS NEW TOOL IS SO CRITICAL DURING FLOODS...IT IS
AVAILABLE FROM TWO SOURCES. THE FIRST SOURCE IS THE NWS ADVANCED
HYDROLOGIC PREDICTION SERVICE /AHPS/ WEB SITE. ON THE AHPS PAGE
FOR THE WINNEBAGO RIVER AT MASON CITY...CLICK ON THE TAB NEAR THE
TOP OF THE PAGE NAMED "INUNDATION MAPPING."  THE DIRECT LINK IS
HTTP://WATER.WEATHER.GOV/AHPS2/INUNDATION/INUNDATION_GOOGLE.PHP?GA
GE=MCWI4 . THE SECOND SOURCE IS THE IOWA FLOOD CENTER/S IOWA FLOOD
INFORMATION SYSTEM /IFIS/. THE DIRECT LINK IS
HTTP://IFIS.IOWAFLOODCENTER.ORG/IFIS/EN/ . GO TO THE FLOOD MAPS
SECTION ON THE RIGHT HAND SIDE OF THE PAGE AND SELECT MASON CITY.

FLOOD INUNDATION MAPS HELP PEOPLE VISUALIZE THE POTENTIAL EXTENT
OF FLOODING AT VARIOUS RIVER LEVELS. THIS INFORMATION CAN ASSIST
IN PLANNING AND MITIGATION DECISIONS.

DR. NATHAN YOUNG...ASSOCIATE DIRECTOR OF THE IOWA FLOOD
CENTER...SAID THE IFC HAS BEEN DEVELOPING FLOOD INUNDATION MAPS
SINCE THE IFC/S INCEPTION IN 2009. "THIS IS AN OPPORTUNITY FOR US
TO APPLY RESEARCH THAT IS USEFUL AND MEANINGFUL FOR IOWANS," HE
SAID. "THESE DETAILED MAPS DEMONSTRATE THE EXTENT OF THE FLOODED
LANDSCAPE WITH EVERY TWELVE-INCH RISE IN THE FLOOD LEVEL. WE
BELIEVE THIS INFORMATION WILL EMPOWER COMMUNITIES AND INDIVIDUALS
TO MAKE INFORMED DECISIONS ABOUT THEIR FLOOD RISKS."

JEFF ZOGG...SENIOR HYDROLOGIST FOR THE NATIONAL WEATHER SERVICE IN
DES MOINES...SAID THE DEVELOPMENT OF THE MASON CITY FLOOD
INUNDATION MAPS WAS A TEAM EFFORT WHICH RESULTED IN VALUABLE TOOLS
FOR PEOPLE IN THE MASON CITY AREA. "MANY PEOPLE WORKED TOGETHER TO
MAKE THESE MAPS AVAILABLE. WE ESPECIALLY APPRECIATE THE
INVOLVEMENT OF EMERGENCY MANAGEMENT AND PUBLIC WORKS OFFICIALS IN
THE MASON CITY AREA. THESE MAPS WILL HELP THE NWS PROVIDE ENHANCED
DECISION SUPPORT SERVICES TO PEOPLE THERE."

STEVE O/NEIL...DIRECTOR OF THE CERRO GORDO COUNTY EMERGENCY
MANAGEMENT AGENCY SAID THAT THE FLOOD INUNDATION MAPS WILL BE
VALUABLE FOR MULTIPLE REASONS. "THE FLOOD INUNDATION MAPS WILL BE
A GREAT ASSET FOR CERRO GORDO COUNTY EMERGENCY MANAGEMENT FOR LONG
RANGE PLANNING FOR OUR COMMUNITIES. THEY WILL ALSO BE INVALUABLE
FOR RISK MANAGEMENT DECISIONS TO ANTICIPATE POSSIBLE TROUBLE AREAS
EARLY ON IN FLOOD INCIDENTS WHICH WILL ALLOW US TO MAKE SOUND
DECISIONS REGARDING EVACUATIONS OR LOCATIONS FOR DEFENSIVE FLOOD
FIGHT TACTICS. OVERALL A VERY USEFUL TOOL FOR THE EMERGENCY
MANAGEMENT TOOLBOX."
