The water levels were measured on February 10, 2015. The measurements <br />were taken after Brannan Sand and Gravel potholed the property in its efforts to eliminate observed <br />ponding on the Einspahr Property. <br />There are two shallow wells on the Einspahr Property (see attached Figure 1). The west well is in a <br />pump house near the Einspahr residence. The east well is located next to the pasture and MW -4 is <br />located on the Brannan property. According to Mr. Einspahr the west well is used in the summer for <br />irrigation of his lawn. The east well has not been pumped for "years ". <br />Three areas of residual ponding were located as shown on Figure 1. These ponded areas are much <br />smaller than the ponding in the past. The West Pond was approximately 10 feet in diameter. The <br />South Pond was about 10 feet wide by 40 feet long and the East Pond was approximately 30 feet in <br />diameter. <br />The water levels at these three ponds were correlated to the elevation of the ground water level at <br />MW -4. It is important to note that we did not correlate the water levels to a mean sea level elevation <br />benchmark as was done in a previous survey. Therefore the water levels are relative to each other. <br />The benchmark is 0.00 for the water level in MW -4. I am also providing a separate relative <br />comparison of the East Well water level to the East Pond and South Pond water levels. The <br />following table and attached Figure 1 show the water levels. <br />1499 W. 1201h Avenue, Suite 200 118 W. 6'h Street, Suite 100 <br />Denver, CO 80234 Glenwood Springs, CO 81601 <br />303 - 452 -6611 <br />www.applegategroup.com <br />
