BLACKFOOT — The Snake River in Blackfoot is expected to rise two feet in two days, once again surpassing flood stage and approaching 11 feet by Saturday.
The National Weather Service has issued a flood warning for the Snake River through this weekend. The Snake River, currently measuring 8.8 feet, will rise to 10 feet by noon Friday and 11 feet by 2 p.m. Saturday.
The rise will be a result of increased flows from Palisades Reservoir, which was 90 percent full Wednesday afternoon. The U.S. Bureau of Reclamation will increase flows from Palisades beginning this morning, increasing to 23,000 cubic feet per second. The increased flows will likely be sustained for 7-10 days, Bingham County Emergency Manager Craig Rowland said.
At 11 feet, flooding will likely occur in the Rose and Riverton areas. The levee at Rose Ponds has not been fixed due to saturation of the ground and Rose Ponds will flood again, Rowland said.
Rowland said most Bingham County residents should still be prepared after many areas flooded in May and June. But Rowland said if the river reaches 12 feet again the impact would be likely be devastating. The Snake River crested above 12 feet May 30, flooding Rose Ponds, Riverview Arena in Firth and several fields throughout the county.
The Snake River is not currently forecast to rise above 11 feet in Blackfoot.
