Hydrologic Outlook
...Hydrologic Outlook - Issued Thursday, March 28, 2013...

Highlights for eastern Iowa, northwestern Illinois, and far northeastern Missouri:

  
  • The spring flood potential is slightly above normal for the lower Rock River.
  • The potential for spring flooding is below normal for the mainstem Mississippi River from near Dubuque, Iowa downstream to Gregory Landing, Missouri, and for the Iowa and Cedar Rivers.
  • Spring flood potential is near normal for all other area tributary rivers across eastern Iowa, northwestern and western Illinois and far northeastern Missouri.
  • Current conditions as of March 28, 2013:
    • Above normal winter season precipitation
      • There is considerable snow pack to the north with water equivalent of 2 inches across southern Wisconsin and southeastern Minnesota, and in excess of 4 inches of water equivalent across portions of central and northern Wisconsin and Minnesota
    • Near to below normal soil moisture
    • Deep frost, especially in areas along and to the north of Interstate 80
    • Near normal stream levels

* The frost depth will be an important factor to watch in the coming weeks. A deep frost could cause increased runoff from any heavy rainfall events that were to occur.

These Hydrologic Outlooks are issued near the end of each month throughout the year. Also, check out the   New Experimental Long-Range River Flood Risk graphical outlook information.
