Rocky Mountain National Park staff was notified last Saturday night that an old culvert in Grand Ditch is leaking at the intersection of Lady Creek and Grand Ditch. The company who operates the Grand Ditch (Water Supply and Storage Company) have made temporary repairs to reduce the leakage and have opened head gates to reduce water flow. The additional water is being rerouted to the Kawuneeche Valley.
Needless to say, RMNP staff quickly began assessing any immediate and potential impacts to trails and bridges in the Kawuneeche Valley as a result.
The Colorado River Trail is flooded approximately 0.6 miles from the trailhead, just beyond the Red Mountain Junction. A sign cautioning conditions was posted at the trailhead, and the staff assures additional assessments are ongoing.
In addition, that was increased sediment movement near Shadow Mountain Reservoir, though it's unclear exactly how much earth was moved in the event.
Grand Ditch Road is currently closed to pedestrians, but there are no other closures in place at this time. Long Draw Road, which leads to this area from just outside RMNP, is closed this time of year - it is still set to open for the season in early July.
