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, nw river forecast. 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 nw river forecast 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.

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. Section 2. Section 3. Section 4. Storage Reservation Diagrams 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.

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.

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.

A significant winter storm is expected to develop over the Northern Plains this weekend before spreading into the Upper Midwest. Widespread showers and thunderstorms will be possible from the Deep South through the Mid-Atlantic. Localized heavy rainfall, gusty winds, hail and a few tornadoes are possible with stronger storms.
