These contours represent water level change in the shallow aquifer in Lahontan Valley from 1992 - 2012 based on depth-to-groundwater measurements made in 73 wells in 1992 and 2012, with limited measurements made in 2013. Measurements collected in 2013 were used to develop the contours only in limited cases where the measurement well was being pumped or was inaccessible in 2012. Water-level change in the shallow aquifer was determined by differencing measurements made in 1992 with current measurements. The difference values were used to interpolate a change surface and contours were developed from that surface.

These contours represent water levels based on depth-to-groundwater measurements made at 98 wells in July of 2012 in the Lahontan Valley near Fallon, NV. Water level measurements collected before or after July of 2012 were included only in cases where the well was being pumped or was inaccessible in July 2012. The contours were developed to compare with 1992 water level altitude contoured by Seiler and Allander (1993).
