Releases Scheduled for the North Fork South Platte (CO)
These kayaking flows are being planned in accordance with the South Platte Protection Plan, which
was developed by water providers, environmental groups, recreation groups, governmental
organizations, local landowners and many other interest groups as an alternative to Wild and
Scenic river designation. Included among the organizations that created the plan are Trout
Unlimited, the Sierra Club, American Whitewater, the Colorado Division of Wildlife, Denver Water
and the U.S. Forest Service. One of the goals of the plan is to enhance whitewater
recreation flows on the North Fork when possible. Denver Water considers the needs of
whitewater enthusiasts when making operational decisions in its water system and at the Roberts
Tunnel. Denver Water’s management of its water system has resulted in many
high-quality kayaking days on the North Fork over the past several years, but this is the first
time we are planning a weekend event.
The Roberts Tunnel delivers water from Dillon Reservoir on the Western Slope to the North Fork of
the South Platte on the Eastern Slope. There are many things to consider in managing tunnel
operations. For example, Denver Water does not take water from the Western Slope unless it
is needed to meet water demands in the city. Rain events that reduce water demands or lack
of sufficient storage space on the Eastern Slope cause reductions in flow through the Roberts
Tunnel.
We have chosen the weekend of August 14–15 because historically Denver Water has been able
to deliver higher flows from the tunnel during August. Denver Water anticipates providing
tunnel flows of approximately 300 cfs which, when combined with the natural flow in the North
Fork, should produce very good kayaking conditions. However, rain or water rights issues
beyond Denver Water’s control may cause those flows to be less. Stay tuned, and we
will let you know how conditions look for the event during the week of Aug. 8.
