    An ice jam pushes water levels close to the top of the levee in Greybull, Wyo. Sandbagging crews from the Wyoming Department of Transportation and the Wyoming National Guard had placed sandbags in low or threatened areas along the Greybull levee at the instruction of John Bartel who was providing technical assistance from the Omaha District.

    Greybull Levee performs as designed reducing risks from ice jam flooding

    While snowmelt and ice jam flooding can occur at any time, they typically occur during early spring thaw. Any ice jam can cause flooding or rapid increases in water levels within a short time period. Residents living near these rivers are reminded to monitor reports closely for ice jam flooding and be prepared to relocate to higher ground if flooding occurs. The levee in Greybull, Wyo., reduced risks to the town during recent ice jam flooding.
  • The scaffolding platform reaches first across the draft tube from the door and then builds out geometrically from the center structure. The hexagonal structure connects to anchor brackets on the draft tube wall and then supports a deck surface, which will accommodate scaffolding to provide safe access to the areas where cavitation impacts the turbine blade and the draft tube liner. Project crew members Mike Schnetzer and Dale Stibral place the scaffolding platform in the draft tube beneath the Kaplan Turbine at Gavins Point Dam.

    Project maintenance, cavitation repairs and OJT

    Among the various projects taking place at Gavins Point Power Plant, generator unit number three was recently dewatered to allow project crews to inspect the draft tube for damage caused by cavitation and make the necessary repairs. Cavitation repairs in the draft tube for unit three will continue through mid-March. Additional maintenance and rehabilitation projects are also underway at the Gavins Point project including replacing three power transformers and rehabilitating the spillway’s tainter gates. Work will move to unit two for annual generator maintenance, to install new un-watering and drain valves, to install a new motor control center, and replace switchgear equipment.
