Table 4. Differences between water levels measured manually and those recorded by the monitoring network, Eastbank Aquifer system, Douglas County, Washington, February 2006 and July 2007.
[Locations of wells are shown in figure 2. USGS well no.: See figure 4 for explanation of well-numbering system. Latitudes and longitudes of the wells are on file with the U.S. Geological Survey. Difference between manually measured and recorded water levels: negative values indicate that manually measured water levels are lower than recorded water levels, and positive values indicate that they are higher. February 6-8, 2006: Values computed from data provided by K. deRubertis and others (written commun., 2007). July 18, 2007: Values are medians of differences computed from multiple measurements between 11:00 a.m. and 3:30 p.m., Pacific Daylight Time. Abbreviations: USGS, U.S. Geological Survey; –, not available]
