Project Description
During the unprecedented flood of September 2013 in the tributaries to the South Platte River, a
significant number of diversion structures and dams along the river corridor were damaged including
the Green Ditch. The flood relocated Boulder Creek upstream of the Green Ditch diversion thereby
leaving the Green Ditch headgate dry. The project included repairing the Boulder Creek channel breach
with compacted embankment material and riprap erosion control. Boulder Creek currently flows in its
pre-flood flowline alignment over the Green Ditch diversion structure. The Company analyzed a plan to
relocate the diversion structure but has since decided to instead focus on fully restoring and improving the
structure at its historic location. Work continues on this front but emergency loan funds will not be needed
to complete the task.
