These data contain groundwater level measurements at 55 locations, used in construction of the potentiometric map of the South Coast aquifer in the Santa Isabel area of southern Puerto Rico during March 31 to April 17, 2014. Measured values of the potentiometric surface ranged from -22.8 feet to 185.4 feet above mean sea level.

A groundwater level survey and reconnaissance of the hydrologic conditions in the South Coast aquifer in the Santa Isabel area of southern Puerto Rico was conducted during March 31 to April 17, 2014. The field survey included groundwater level measurements at 55 wells and instantaneous streamflow measurements at 15 locations in streams and irrigation canals. A potentiometric surface map of the alluvial aquifer provides an indication of the directions of groundwater flow. The objective of the field survey was to delineate the potentiometric surface of the study area defined as the South Coast aquifer between the Río Descalabrado to the west and the Río Jueyes to the east of the town of Santa Isabel. Instantaneous streamflow measurements were made at selected sites along the Río Coamo, Río Descalabrado, Río Cañas, and the Canal de Juana Díaz to evaluate groundwater and surface-water interactions during the synoptic survey. Potentiometric contours are based on water-level measurements collected at wells during the dry season from March 31 to April 17, 2014. Measured values of the potentiometric surface ranged from -22.80 feet to 185.4 feet above mean sea level. The results of the study indicate a cone of depression in the aquifer near the center of the study area, where the potentiometric surface is below mean sea level.

This dataset contains stream-stage data for the Santa Cruz River near Nogales International Wastewater Treatment Plant Upstream of Railroad Trestle (SC5). The pressure transducer was mounted to a metal post secured in the stream near the right bank. The data were recorded using non-vented Solinst Levelogger for the period of February 12, 2015 to December 31, 2016. The data were logged continuously at a 15-minute interval and manually downloaded. Data were corrected with the atmospheric pressure collected from a Solinst Barologger located at SC14 and checked for erroneous data.

This dataset contains stream-stage data for Santa Cruz River at Santa Gertrudis Lane (SC10). The pressure transducer was mounted to a metal post secured in the stream near the right bank. The data were recorded using non-vented Solinst Levelogger for the period of February 12, 2015 to December 31, 2016. The data were logged continuously at a 15-minute interval and manually downloaded. Data were then corrected with the atmospheric pressure collected from a Solinst Barologger located at SC14 and analyzed for erroneous data.

This dataset contains stream-stage data for Agua Fria Canyon near Rio Rico, Arizona (AF2). The pressure transducer was housed in a crest-stage pipe mounted to the bridge pier of West Frontage Road. The data were recorded using non-vented Solinst Levelogger for the period of October 7, 2015 to December 31, 2016. The data were logged continuously at a 15-minute interval and manually downloaded. Data were corrected with the atmospheric pressure collected from a Solinst Barologger located at SC14 and checked for erroneous data.
