Army Corps flood teams remain, provide assistance for anticipated rise in flood waters

Published May 21, 2018

SEATTLE— Flood teams from the Seattle District, U.S. Army Corps of Engineers, are continuing to monitor levees and providing technical assistance to local communities as receding floodwaters are expected to rise again in the coming days. 

Yesterday flood teams completed the last of 13 direct assistance requests in Okanogan, Washington, and initiated a $161,550 project to stabilize and protect the Turah Levee in Missoula County, Montana. Work also continues in Plains, Montana and on a flood berm in Pend Oreille County, Washington.

Teams are providing technical assistance to Missoula County, Montana; Yakima, Stevens and Pend Oreille County, Washington; Twisp, Washington; Benewah County, Idaho, and the Kalispel and Colville Confederated Tribes.

The Seattle District has provided about 1,460,500 sandbags so far to Okanogan County, Pend Oreille County and Tonasket in Washington; Missoula County in Montana; Bonner County, Idaho; and to the Kalispel and Colville Confederated Tribes. USACE has provided 2,800 Supersacks to Missoula County and Okanogan County, and five pumps with 1,400 lineal feet of hose to the Okanogan basin. USACE also delivered 2,700 lineal feet of Hescos to Pend Oreille County.

Warm temperatures combined with above normal snow levels have created a situation where Pend Oreille River flows downstream of Albeni Falls Dam are likely to remain above flood stage through the 10-day forecast period and beyond. Flows on the Pend Oreille River and Lake Pend Oreille are now forecast to meet or possibly exceed 2011 levels. Albeni Falls Dam operational information is available on line at:

Corps of Engineers’ officials warn boaters and the public to be safe and watch out for floating or submerged logs or debris on Lake Pend Oreille. For safety purposes, all of Albeni Falls' boat ramps are closed including Riley Creek's. The Corps’ swim beaches are all closed for swimming. There is no re-opening scheduled yet.

Flood fight teams are coordinating with the States of Washington, Idaho and Montana. Agency representatives will continue to coordinate with the Tribes, counties and cities along the rivers.

Public Law 84-99 authorizes USACE to provide flood fight assistance at the request of local officials when rivers are at or above flood stage and local resources are fully used.

Private citizens seeking sandbags should contact their local government offices. 

USACE coordinates closely with the National Weather Service. The Weather Service issues flood watches and warnings and should be consulted for that information.
