Take a tour of the Sacramento District's new Isabella Lake Dam scale model at Utah State University's Water Research Laboratory in Logan, Utah. Engineers from the U.S. Army Corps of Engineers Sacramento District's Isabella Dam Safety Modification Project team tested the model against the most extreme storms and water flows on Feb. 12-13. The 1:45 scale model is an essential part of the Corps' pre-construction engineering and design phase and allows engineers to test the design and improve it before construction begins. Construction of Isabella Lake Dam upgrades is scheduled to begin in 2017. Photos: http://bit.ly/1ms3YiF
