Site Details

• 

• Snow surveys provide 30+ years of spatially distributed snow water equivalent (SWE) and snow depth observations. Annual snow surveys from the Imnavait Creek (20,036 measurements from 1985 to 2017) and Upper Kuparuk River (5,804 measurements from 1997 to 2017) watersheds were conducted to capture end-of-winter snow accumulation.

  The end-of-winter snow surveys occur once a year around late April. Snow sampling protocols include gravimetric SWE measurements and snow depth measurements collected over the snow course area.
