Table 3. Summary of daily precipitation, snow pillow (snow water), and lysimeter (snow melt plus precipitation) from Upper Lookout, Hi-15, Vanilla Leaf, and Central Meteorological Stations, H.J. Andrews Forest, for February 1-10, 1996. Snowmelt is calculated as the difference between lysimeter outflow and precipitation; negative snowmelt represents snowpack storage of water. Total water available is calculated as the sum of previous day's snow water plus current day's precipitation.
