EX-6 Rain Gage, Macheche, Guam PERIOD OF RECORD.—New station, established May 20, 2004. Record from May 20 to December 17, 2004. EX-6 Exploratory Well 133034144500871, Local number, 18-3050-04 Macheche Exploratory Well EX-6 LOCATION.--Lat 13° 30' 34' N., Long 144° 50' 08" E., Hydrologic Unit 20100003, Macheche area. Owner: Government of Guam AQUIFER.--Barrigada Limestone WELL CHARACTERISTICS.--Drilled basal ground water exploratory well. Sounded depth at time of drilling 407 ft, Well deepened to 462 ft in August, 1981. Sounded depth for this study 448 ft, Borehole diameter 12 in., Casing diameter 6 in., cased to bottom. DATUM.—Altitude of land surface datum is 309 ft. Measuring point and new altitude (determined for this study): black inked triangle on top of PVC 6-in. casing, 309.06 ft above mean sea level. Old measuring point and previous measuring point altitude: top of steel surface casing, 309.40 ft above mean sea level.
