Maps showing ground-water conditions in the upper San Pedro basin area, Pima, Santa Cruz, and Cochise Counties, Arizona; 1978
A.D. Konieczki
1980, Open-File Report 80-1192
The upper San Pedro basin area includes about 1,800 square miles in southeastern Arizona. The main use of groundwater is for irrigation. During 1966-77, about 481,000 acre-feet of groundwater was withdrawn. Except near Sierra Vista and Fort Huachuca, the groundwater withdrawals have had little effect on water levels. Information shown...

A primary monitoring network of 12 stations, with measurements at 1-meter depth intervals every 2 weeks during periods of high inflow from the Sacramento-San Joaquin River delta, and every 4-6 weeks during seasonal low delta inflows, appears adequate to observe major changes in ambient water quality in San Francisco Bay....
Map showing the potentiometric surface of the Aquia Aquifer, May 19-23, 1980
Frank Chapelle, Dave Drummond, Tracey Curley
1980, Open-File Report 81-416
The map is based on water level measurements made May 19-23, 1980. The well network used included 83 wells which have been screened in the Aquia aquifer (Aquia Formation of Paleocene Age). Highest levels of the potentiometric surface, 20 to 35 feet above sea level, were measured near the outcrop...
