Meeker. Ice jams can occur at bridge crossings and channel constrictions where flooding can <br />occur from otherwise non-damaging flows in areas ordinarily only affected by much higher flows. <br />The jams can reduce channel capacity so much that the small flows cause significant flooding. <br />' Additionally, ice jams can release stored water without warning when the jams fail, causing a <br />destructive wave to move downstream. Rain on snowmelt floods result from the augmentation <br />of already high snowmelt flow volumes by the added runoff of rainfall. These types of floods <br />can be characterized by the already moderate peak flows of snowmelt floods followed abruptly <br />by a short duration high flow. The construction of a dam approximately 7 miles upstream of <br />Rangely, although not constructed for flood control purposes, is expected to reduce the flooding <br />caused by ice jams in Rangely by altering the temperature patterns in the river. <br />8
