(Rick Bowmer | The Associated Press) This Thursday, Nov. 7, 2019 photo, shows the Mountain Dell Dam, 5 miles east of Salt Lake City. The window-like arches on the outside of the towering Mountain Dell Dam provide an artistic facade that fits with the natural beauty of the Utah mountain canyon where the century-old structure sits. The dam is listed in poor condition because of deteriorating concrete that allows seepage from the reservoir, said David Marble, Utah assistant state engineer.
