Reservoirs fill and spill

Several Denver Water reservoirs filled this spring during the runoff. Cheesman, Strontia Springs, Eleven Mile Canyon and Williams Fork all had water going over the spillways.

The high water allowed Denver Water to conduct the first full-capacity test of Cheesman Dam’s jet flow gate on June 10 and 11, 2014. The gate was installed in 2012 as part of a project to upgrade the dam. The dam’s valve system controls the amount of water flowing from the reservoir into the South Platte River. Water successfully passed through the gate at a rate of 937 cubic feet per second.

Check out the photos and video 7News captured from a helicopter during the test.

Jeff Martin, Denver Water engineering project manager, said the test was successful and the gate will provide better redundancy in dam operations.
