(Radio Iowa) – Officials with the U-S Army Corps of Engineers will cut short the navigation season on the Missouri River this fall due to the continued drought. John Remus, chief of the Corps’ Missouri River Basin Water Management Office, says they’ve been conserving water for months. “We restrict our releases from Gavins Point, we start cutting service to navigation,” Remus says. “When that both is a lesser service during the flow support season and then if it gets worse, we will make that flow support season shorter.”

Clear signs of the drought first began to emerge in July of 2020, and Remus says one priority is to keep a reserve of water in the upstream reservoirs. “If it gets real bad, if we reach a certain level of storage in the system, we don’t support navigation at all for that year,” Remus says, “and if we ever reach that, and we never have, we could maintain that lower level of service to all the other purposes, even if we get what we call lower decile run offs which are very, very dry years.”

The Corps has cut back releases, dropping Missouri River levels by a full foot, which will impact boat traffic and could affect municipal water supplies and other utilities that rely on the river. Navigation continues on the Missouri, though barges will have to lighten their loads to float. Remus says the navigation season will end November 28th, which is three days early.
