Army Corp of Engineers Uses Fly Ash to Battle Flooding

(KETV 2-9-10) The U.S. Army Corps of Engineers is racing the clock as it builds a new line of defense along the Platte and Elkhorn rivers. They are trying to complete their work before the ice melts, bringing the potential for flooding. On Monday, the Corps was shoring up the levee where Salt Creek meets the Platte River.
“The levee stretches from Highway 6 over to Thompson Lakes, which is about three miles,” said Paul Johnston with the Army Corps of Engineers. Plans have been in the works for years to add to the levee. Now it will be eight feet higher. Johnston said that’s important because the potential for flooding is high this year. Engineers said they don’t want the ice to melt too fast on the river. That could lead to ice jams and eventual flooding. To avoid that, the Army Corps is planning to spread a material called fly ash on the ice. “We provided the state with recommendations that they dust,” said Johnston. “We’re looking at six locations along the river.” Officials said they intend to start spreading the fly ash next week.
