View a list of all agencies providing funding for this site.
Here is a partial description of the hydrographs.
  • Note left vertical coordinates are in feet, right vertical coordinates are in Cubic Feet Per Second.
  • Horizontal scale is time with the forecast issuance time centered, this is also indicated by the vertical dashed blue line.
  • The magenta 'x's are the actual forecast. The green 'o's are observed values. The black 'N's are USGS median daily flows (where available).
  • There may or may not be a horizontal dashed line which indicates flood stage and a horizontal dashed blue line which indicates flood of record.
Here is a partial description of the text guidance.
  • The text-based guidance uses Standard Hydrometeorological Exchange Format (SHEF) code and contains a time series of forecast river heights every six hours.
  • Two forecasts are issued for each point; one with forecast precipitation included (the official guidance) and one without forecast precipitation.
  • If flooding is imminent or occurring, the guidance may also include flood crest information and forecaster commentary.
  • These guidance products are internal NWS products as produced by the ABRFC for use by NWS WFOs (National Weather Service Weather Forecast Offices) and various other entities. Official flood forecasts are those as issued by the appropriate NWS WFO.
Observed data and other information about the gage sites and river information comes from a variety of sources including the United States Geological Survey and the Army Corps of Engineers.
