Some rivers may exceed bankful due to this combination of snowmelt and heavy rains. Record flows are expected on the Snake River from the Palisades Dam to the confluence with the Henrys Fork River. The required releases from the Palisades Dam are the highest at Heise since the dam was constructed. These extremely high flows will cause some irrigation channels to overflow their banks with potential flooding well away from the main Snake River channel. Recent rainfall has caused the Big Wood River to rise rapidly, with flooding of low lying areas.
Flooding continues at several locations along the lower Ohio River.
This river flooding is the result of runoff from heavy rain in the area the last part of last week and the first of the weekend. The river has crested or is cresting at some locations along the river, affecting mainly agricultural and bottom land. Extensive lowland flooding will continue in the Mount Carmel area through Sunday. The crest on the Wabash River is approaching Mount Carmel Illinois as the combination of high water from the White River and another rise traveling down the Wabash River contributed to the high water. Upstream, lowland flooding extends from Lafayette to Vincennes.
