Michael Johnson, lead project engineer, looks at the water flow from a 1:50 scale model of the Oroville Dam spillway at Utah State University’s Utah Water Research Laboratory in Logan on Friday, June 16, 2017. The approximately 100-foot-long, 60-foot-wide model replicates the spillway in its current state and features the terrain conditions that were formed following the damaging flow events in February. USU engineers are taking measurements on various sections of the model to determine depth of flows, wave action, pressures, velocity profiles and more.
