Brief Information about the Advanced Hydrologic Prediction Service (AHPS)
AHPS reduces loss of life and property, mitigates flood damages (three fourths of all Presidential Disaster Declarations involve flood damages).  AHPS river, flood and drought forecasts are prepared by hydrologists and hydro-meteorologists at the both the Ohio River Forecast Center and the Paducah Weather Forecast Offices.  AHPS provide forecasts of river levels and river flow volumes from an hour to a season for areas large and small, including river forecast information such as:

• How high the river will rise
• When the river will reach its peak

• the chance or probability of a river exceeding minor, moderate, or major flooding,
• How long flooding will continue

What is the Source of AHPS Real-time Observational Data?
The majority of the observed water level data displayed on the AHPS web pages originates from the United States Geological Survey's (USGS) National Streamflow Information Program which maintains a national network of streamgages. In addition, real-time water level information is collected from other federal, state, and local streamgage networks.
