(Burns, OR) -- Evacuation levels in Harney County stay unchanged as the Silvies River will remain at minor flood stage due to warm temperatures melting the snowpack. The U.S. Army Corps of Engineers completed work reinforcing a dike with large permeable rock. They say some water will flow through the dike, but the heavy rock is expected to hold most of the water back. Cleanup work is underway in Burns and at the Burns Paiute Tribe. Public health officials continue to warn about health risks in flood water. The drinking water is safe.
