Interior Flooding

Flooding from the regionally heavy rains continue on this Summer Solstice Day 2014. The Salcha River at the Richardson Highway Bridge crested at 11pm Friday with a gauge height of 18.34 feet, as seen in this hydrograph:

This is the fifth highest crest of record for the Salcha, and the third highest summer crest (the other two being spring break-up floods), and the highest summer crest since August 1986.

On the Chena River, the river crested at the Granite Tors Campground late Friday morning and has now reached the Moose Creek flood control project. At both the upper Chena and Hunts Creek guage (above the dam) this was the 6th highest of record and highest crest since 2003.
