Snow packs in the mountains of the Pacific Northwest remain above normal. However, the area of significant snow cover yet to be melted is mostly in the Columbia Basin in Canada. The Lower Columbia River will remain high for the next several weeks, but only minor flooding is expected. Due to increased releases from Grand Coulee Dam, higher water levels are currently moving down the Middle Columbia River. Outflows from the Priest Rapids Dam will be fluctuating from 2 feet below to 2 feet above the 432 foot flood stage.
Flooding continues at several locations along the lower Ohio River.
Minor flooding of lowlands adjacent to the river will diminish as the river is expected to fall below flood stage over the weekend. Many rivers in southeast Colorado continue running high due to the recent heavy rainfall and saturated soils. The Arkansas River and Beaver Creek were both reported over their banks at some locations. Extremely high flows on the Upper Snake River will be moving downstream. These high flows will cause flooding along the banks of American Falls, Minidoka and Milner Reservoirs and along the Snake River channel between the dams.
