A multiphase project to replace spillway gates at urlow Dam
started this summer and will continue into 2019.
e water level at urlow was lowered as much as 10 feet in
June to accommodate the project.
e 2018 drawdown is tentatively scheduled to end this fall,
with water levels returning to normal pool level. A similar
drawdown is planned for 2019 from June through October.
e drawdown is needed to replace the dam's spillway crest
gates, known as flashboards, which were installed in the 1920s.
e steel replacements, called Obermeyer gates, will be more
efficient than the old, 36-gate flashboard system. Obermeyer gates
use adjustable, inflatable bladders to control the gates and more
accurately manage water resources.
