Dillon

Denver Water participated in the Coordinated Reservoir Operations study process, however, no releases
from Dillon Reservoir were made during 1997. Dillon Reservoir was prepared to make bypasses, but it
was determined that they would not have been passed through Green Mountain Reservoir due to capacity
limitations at the Green Mountain Reservoir Hydropower Plant.
