10) Groundwater-level change for Smith Valley and Mason Valley, Nevada, 1996-2006, approach 2

This raster dataset represents groundwater-level change from 1996 to 2006 in Smith Valley and Mason Valley, Nevada, calculated using approach 2. For this approach, depth-to-water measurements from 53 monitoring wells, represented as point values, were differenced between 1996 and 2006. Point values of change were interpolated into a raster to calculate valley-wide groundwater-level change. Groundwater-level change was estimated using two methods (approach 1 and 2) to address groundwater-level measurement uncertainty and constrain groundwater-level change estimates.
