The Missouri River basin has enough water for the Corps of Engineers to provide flow support for a full navigation season, the Corps' Missouri River Basin Water Management Division announced July 10. Above-average rainfall and fast-melting snow led to above-average runoff in the upper basin in June. Runoff above Sioux City, Iowa, was 6.7 million acre-feet (maf), 122 percent of average. The updated forecast for full-year runoff above Sioux City is 29.2 maf, which would be 114 percent of average. "The annual forecast for the upper basin has been increased due to the rainfall and snowmelt in the month of June," said John Remus, chief of the division. "The mountain snowpack has completely melted out, approximately two weeks ahead of schedule, further increasing the June runoff. The basin will need additional rainfall to continue the trend of above-average runoff." |
