Kootenai River in Northern Idaho Not Expected to Rise – Levee System Weak

There is good news for now for residents near the Kootenai River at Bonners Ferry in northern Idaho, close to the Montana border. The river is not expected to rise above flood stage today, as predicted by water managers.

They expect the water level in the Panhandle River should stay a half-foot below the flood mark and should continue to drop later today.

However, more rain and warmer temperatures could cause more natural run-off from the mountains, more outflow into the river from Libby Dam in Montana, and therefore pose a threat for flooding and further weakening of the levee system.

The Army Corps of Engineers (USACE) has completed an assessment of the status of 100 miles of levee system within the county.   They are estimating that 51 miles of the levee has received damage.  The USACE continues to repair and shore up levees within the city of Bonners Ferry.  Region X staff is in contact with USACE staff.

The City of Bonners Ferry and Boundary County have declared local Disaster Emergencies and opened their Emergency Operations Centers (EOC).  The State Department of Environmental Quality continues to monitor the threat to potable water and waste water systems in cooperation with city and county officials. The State Bureau of Homeland Security EOC has been activated to a level 3. The Governor has issued a State Disaster Declaration for Boundary County. The Local and State are discussing the potential for a Federal Request for Disaster Assistance. (Region X, media sources)

In southwestern New Mexico's Gila National Forest, 12 miles northeast of Silver City, a lightning-sparked fire that burned at least 8,500 acres forced the evacuation of about 200 homes after wind gusts of about 40 mph pushed the blaze over a hand-cleared line. No homes had been damaged and the fire was 30 percent contained by Friday night, authorities said.
