The US Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS) operates a near real time remote snow measuring system called SNOTEL in the Western US. The SNOTEL system has been in full operation since 1980 and currently has 693 stations across the West. Each station collects snow water equivalent, precipitation and temperature. Additional sensors can be installed at the remote sites to measure other types of data of interest to the cooperators. One of the additional sensors are ultrasonic snow depth sensors which were field tested on the SNOTEL system in 1996. This study focuses on the results of the 1st year of operation of depth sensors installed at 3 stations on Mount Hood in the Cascade Mountains located East of Portland, Oregon. These sensors were installed to add to the snowpack information already collected at the sites. This additional information has improved our knowledge on how the snowpack reacts during melt events
