This FCOP supersedes all previous versions. Storage Reservation Diagrams SRD define the flood control space required in each nw river forecast to provide flood protection for the Columbia River. Storage space required is a function of time of year and the seasonal runoff volume.

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.

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. VARQ reduces the contribution of reservoir space at Libby and Hungry Horse for system flood control of spring runoff in the Columbia River in years with low to moderate potential for flooding. The procedure was designed to provide higher outflows from the projects during the spring runoff than under the current flood control operation as outlined in the Columbia River Treaty Flood Control Operating Plan. These outflows are more consistent with releases made to meet flow objectives for the listed Endangered Species Act Kootenai River white sturgeon and Columbia and Snake River salmon and steelhead. The report is comprised of an Executive Summary and four sections, which are listed below. Section 1.

This office specializes in flood and water resource forecasting, river modeling, and hydrologic system development. It works with water management agencies to provide the best possible operations of the Columbia reservoir systems. The center is very active in recreational and navigational hydrological forecasting. Mission: - To save lives and decrease property damage by the issuance of flood warnings and river stage forecasts. Provide basic hydrologic forecast information for the Nation's economic and environmental well being. Provide extended forecast information for water resources management. Service Area: - The area of responsibility encompasses over , square miles and includes parts of 7 states and parts of western Canada. Flood Forecasting: - Floods are a natural and inevitable occurrence along the rivers of our country.

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.
