Due to Coralville Lake’s constant flow of water, ice on the reservoir is vastly different from ponds, small lakes and even Lake Macbride. Water levels at Coralville Lake can also fluctuate daily causing ice to weaken. Frozen portions of the lake may no longer be supported by water if levels drop and could give way at any time. These ice shelves can also cause dangerous slopes and ice bridges which can make escape or rescue from the ice nearly impossible.

For information on lake levels and reservoir conditions, contact the Coralville Lake Administration Office at 319-338-3543 ex. 6300 or Coralville.lake@usace.army.mil. Information about the lake and its conditions can also be found on the Coralville Lake Facebook page at www.Facebook.com/coralvillelake.
