River Flows Are Highest in a Decade
IDAHO FALLS (AP) — The South Fork of the Snake River is flowing at more than 10,000 cubic feet per second, the highest rate measured in decades on Sept. 1.
In recent years, the river that cuts through southeastern Idaho typically drops to 8,000 cfs by the end of August. But Mike Beus, a Bureau of Reclamation hydrologist, says irrigation demand and water supply is allowing for the higher flows.
The river flowed at 13,100 cfs on Sept. 1, 1966. That marked the last time the river, which is controlled by the Palisades Dam, was measured at more than 10,000 cfs on that date.
Beus says cool weather in the spring delayed the onset of the growing season, creating the late season demand for water.
Palisades Reservoir was 99.9 percent full in June, but is now 58 percent full.
