PER COORDINATION WITH LOCAL OFFICIALS, THE NWS IN DES MOINES WILL

AND TIME MENTIONED ABOVE. THE RIVER FORECAST SERVICES WILL CHANGE 
DURING THE WARM SEASON TO DAILY MORNING RIVER FORECASTS. THE WARM

AS HAS BEEN THE CASE FOR ALOI4, RIVER FORECASTS AND FLOOD WARNINGS 
WILL CONTINUE TO BE VALID ALONG THE REACH OF THE CEDAR RIVER 
EXTENDING FROM THE WATERLOO-CEDAR FALLS CITY LIMITS TO SPRING 
CREEK NEAR LA PORTE CITY.

THE CEDAR RIVER AT WATERLOO IS A REAL-TIME U.S. GEOLOGICAL SURVEY 
(USGS) STREAMGAGE WHICH PROVIDES STAGE DATA. THIS STREAMGAGE HAS A 
PERIOD OF RECORD BACK TO 1941. IT IS MAINTAINED BY THE USGS FIELD 
OFFICE IN FORT DODGE AND IS FUNDED BY BOTH THE USGS AND THE CITY 
OF WATERLOO.


...CONCLUDING REMARKS...

AS WITH OTHER NWS RIVER FORECAST POINTS, THE NWS WILL PROVIDE 
RIVER FORECASTS WHEN THE OBSERVED OR FORECAST STAGES GO ABOVE THE 
FORECAST ISSUANCE STAGE, ALSO KNOWN AS THE ACTION STAGE. IN 
ADDITION, THE NWS WILL ISSUE RIVER FLOOD WARNINGS AND FOLLOW-UP 
RIVER FLOOD STATEMENTS WHEN THE OBSERVED OR FORECAST STAGES GO 
ABOVE THE FLOOD STAGE.

ALSO, RIVER FORECASTS FOR THE ABOVE LOCATION WILL BE AVAILABLE ON 
THE NWS ADVANCED HYDROLOGIC PREDICTION SERVICE (AHPS) WEBSITE. IN 
ADDITION, RIVER FORECASTS FOR THIS LOCATION WILL BE UPDATED AS 
NEEDED WHILE THE STREAM REMAINS AT OR ABOVE THE FORECAST ISSUANCE 
STAGE IN THE EVENING DURING THE WARM SEASON, AND DURING BOTH THE 
MORNING AND EVENING IN THE COLD SEASON.
