VARQ was developed to improve the multi-purpose operation of Libby and Hungry Horse while maintaining the current level of system flood control protection in the Columbia River.

This FCOP supersedes all previous versions. Storage Reservation Diagrams SRD define the flood control space required in each reservoir to provide flood protection for the Columbia River. Storage space required is a function of time of year and the seasonal runoff volume. The diagrams are designed to provide an orderly evacuation of each reservoir prior to the reservoir refill period with consideration to project operating limits and the regulation of the Columbia River reservoir system.

Atmospheric rivers are expected in the Pacific Northwest this week as heavy rainfall continues to deluge the region. The National Weather Service on Saturday issued a flood watch for most of southwest Washington and northwest Oregon that will remain in place until Wednesday afternoon. Flooding may occur in poor drainage and urban areas. Atmospheric rivers are long regions in the atmosphere that transport water. The water vapor they carry is roughly equivalent to the average flow of water at the mouth of the Mississippi River, according to the National Oceanic and Atmospheric Administration. When the rivers make landfall and release all that water, they can cause extreme flooding. Rain amounts through Sunday afternoon are expected to be anywhere from inches along the south Washington and north Oregon coast, and up to 2 to 5 inches over the Coast Range and Willapa Hills, according to NWS. Oregon's Coast Range could see between inches of rain. Heavy snow, rain lash Pacific Northwest. Please enter email address to continue. Please enter valid email address to continue.

The forecast shows near-average water supply in the northern half of the Columbia River Basin and below-average supply in the southern half. Abnormal to severe drought , particularly in Oregon, affected some regions in the southern half of the Columbia River Basin. Overall, EIA expects the forecast of near-to-below normal water supply across the region to decrease the electricity generated from hydropower this summer. As such, hydroelectric supply in the Pacific Northwest can have implications for the use of other electricity-generating fuels in the region, such as natural gas, and for electricity trade with neighboring areas. Two main factors help predict water supply in the region: seasonal precipitation and snowpack accumulation.
