Upgrades to the hydropower generators at Gavins Point Powerplant will result in water flows through the spillway gates. When the generators shut down for the upgrades, water that normally runs through the powerplant will be diverted to the spillway.
Spillway flows are expected to begin on Feb. 26 and continue through approximately May 15.
Boating restrictions will be in place on the Missouri River below Gavins Point Dam during this time. When water is released through the spillway, hazardous conditions may exist for vessels on the river and boaters are urged to use caution. The restricted area for boats is marked by signs located on the north and south bank of the Missouri River approximately 500 yards below the spillway. During spillway releases boaters will not be allowed to go upstream of these signs.
