<br />2.5 Flood Characteristics
<br />
<br />Major flooding in the White River basin has been primarily the result of rapid snowmelt
<br />beginning as early as late April. Snowmelt flooding can continue into early July. Flooding can
<br />also occur from rainfall on snowmelt and from ice jams in late winter or early spring. Due to
<br />the sma1l areal extent and limited duration of thunderstorms, they do not typically constitute a
<br />major flood threat on streams as large as the White River. They do, however pose a problem for
<br />some of the smaller tributaries in the White River basin.
<br />
<br />Snowmelt flooding is characterized by moderate peak flows, large volume of runoff, long
<br />duration, and diurnal fluctuation of flow. Flooding from general rainfall alone, though
<br />uncommon on the White River, is characterized by high peak flows and moderate duration of
<br />floodflows. Historically, ice jams, rain on snow, and local thunderstorms have caused the greatest
<br />flooding around Rangely. Snowmelt floods of 1983 and 1984 produced 100-year flows at
