Missouri River Water Management July Update

12 Jul 2018 5:13 PM | Tom Poer (Administrator)

MOARC continues to monitor flow releases from the upper basin mainstem reservoir system to the lower basin and its effect on the interests and economy of the region and MOARC membership. The Corps of Engineers (Corps) water management offices are reporting waters currently stored in the upstream reservoirs are at levels reaching into the flood exclusion zone.  Due to the higher-than-average upstream runoff forecast in the upper basin the Corps has increased the system’s flows to 25,000 cfs above full service levels to facilitate the continued evacuation of stored flood waters. Storage issues and releases continue to be driven by the melting of the above average mountain snowpack and moderate heavy plains snowpack along with periodic rainfall events across the basin. 

The increased service level means that Gavins Point releases will be increased to approximately 60,000 cfs, as downstream tributary flows recede.  Gavins Point releases to the lower basin will remain near 60,000 cfs for the remainder of the navigation season to ensure evacuation of all stored flood waters.   Storage within the mainstem reservoir system (storage was 67.8 MAF as of July 1, occupying 11.7 MAF of the 16.3 MAF flood control zone. The Corps reports that approximately 25 percent of the system’s flood storage remains available to capture additional runoff and provides the system flexibility to lessen downstream flooding.
