1 Latitude and longitude determined using global positioning systems based on 1983 datum. Altitudes estimated from U.S. Geological Survey 1:24,000-scale maps: Ruby Lake NW, 1968; Franklin Lake SW, 1968; Sherman Mountain, 1985.
2 See section "Methods of Estimating Evapotranspiration" for description of each method.
3 Plant cover: sparse, 5 to less than 25 percent; moderate, 25 to less than 75 percent; dense, 75 percent or greater. Only dominant plants are listed in order of relative abundance. Water depths are for period of ET data collection and were estimated from water levels measured in selected wells (fig. 2).
