INTRODUCTION along the San Pedro River about 6 miles long and several miles wide at the northern boundary of the San Pedro Riparian National Conservation Area had increased water Depth to water (DTW) measurements were taken in the Upper San Pedro basin by levels in most of the wells from about 0 to 5 feet. Water levels generally decreased from 0 personnel of the Arizona Department of Water Resources at 636 wells from November 14, to 5 feet in wells more than a few miles from the river. Hydrographs of the wells in this 2001 to December 14, 2001, and at 596 wells from November 27, 2006 to December 18, area generally do not exhibit significant long-term trends (hydrographs E, F, and G). 2006. These data were reviewed, and measurements made with accompanying remarks (potentially indicating non-standard conditions of water-level measurements) were not Tombstone included in this analysis. The most common remarks related to known pumping, but Water-level changes in wells in Tombstone ranged from an increase of 7 feet to a R21E several measurements were remarked for having anomalous water levels that may have decrease of 11 feet.

Regardless, the water level in this well has been significantly declining at an increased (water-level decline) in 241 of the wells, remained unchanged in 8 wells, and average rate of 1.1 ± 0.1 feet per year since 1973. Also, the water level in a well located at T12S decreased (water-level rise) in 118 wells. The water-level changes ranged from an D-21-20 16AAC (hydrograph I) has been significantly declining at a rate of 0.629 ± 0.002 increase of 33.4 feet to a decrease of 30.2 feet. Most of these large changes – both feet per year since 1977 (the standard error of the slope of this trend is small due to the increases and decreases – occurred near streambeds and mountain fronts and are fact that this well is equipped with automated monitoring equipment taking 4 susceptible to large short-term water-level fluctuations due to recharge events. measurements daily, and there are thousands of measurements collected since February, 2001). Other hydrographs from wells in this area also exhibit long-term declines in water North of Little Dragoon Mountains levels (hydrographs L and M). Water-level changes north of the Little Dragoon Mountains are generally small, ranging 3 from a decline of -9 feet to a rise of 3 feet. The hydrograph of a well near the Tres Alamos Sierra Vista – Charleston Wash (hydrograph A) is shown on sheet 2. From northeastern Sierra Vista to Charleston, most of the water levels of wells have -1 increased, ranging from a decrease of 2 feet to an increase of 19 feet. This is the location -1 0 San Pedro River North of Benson of the new Sierra Vista Environmental Operations Park which opened in 2002 and is using Water levels of wells within several miles of the San Pedro River north of Benson generally treated water to recharge the aquifer. The hydrograph of a well located at D-21-21 22DDC -2 -3 declined, ranging from 0 to 19 feet. The hydrographs of these wells do not typically exhibit does not exhibit a significant long-term trend (hydrograph K), but the water-level rise since T13S significant long-term trends (hydrograph B). 2001 may reflect the influence of the recharge from the Sierra Vista Environmental Operations Park. Benson Water levels of wells in the vicinity of Benson ranged from an increase of 20 feet to a Hereford – Palominas decrease of 16 feet. Many of these wells are completed in both a shallow aquifer and a Water-levels of most wells in this area have increased slightly, ranging from a decline of 3 -9 deeper (artesian) regional aquifer (Barnes and Putman, 2003). Most of the water levels of feet to an increase of 11 feet. The hydrographs of these wells do not typically exhibit the wells to the west of the San Pedro River decreased. Hydrographs of many of these significant long-term trends (hydrograph N). wells exhibit a significant long-term decline; the water level of a well located at D-17-19 Upper San Pedro Basin 14ACA, for example, has declined about 0.63 ± 0.04 feet per year since 1982 (hydrograph Bisbee – Naco C). However, not all hydrographs of wells in this area show a significant trend (hydrograph Water-levels of most wells in the area of Bisbee and Naco have been significantly D). Water-levels to the east of the river generally increased, but hydrographs of the wells decreasing for years. Water levels of most wells in this area decreased about 7 feet in five in this area do not typically exhibit any significant long-term trends. years from 2001 to 2006. A general decrease of about 25 feet from 1990 to 2001 was
