Summary
Tumacácori National Historical Park (TUMA) was established in 1908 to protect, preserve, and communicate the history of the old Spanish and O’odham mission church. In 2002, Congress expanded the Park’s purpose and mission, increasing the Park’s area to include more than 1 mile of the Santa Cruz River and its associated riparian area. As part of the USGS–NPS Water-Quality Partnership, a three year investigation was conducted to provide TUMA with a better understanding of the spatial and temporal variability of Escherichia coli (E. coli) concentrations and sources within and upstream of the Park. The supplemental data release includes stream-stage datasets collected by the USGS using pressure transducers and effluent-discharge and E. [...]
Summary
Tumacácori National Historical Park (TUMA) was established in 1908 to protect, preserve, and communicate the history of the old Spanish and O’odham mission church. In 2002, Congress expanded the Park’s purpose and mission, increasing the Park’s area to include more than 1 mile of the Santa Cruz River and its associated riparian area. As part of the USGS–NPS Water-Quality Partnership, a three year investigation was conducted to provide TUMA with a better understanding of the spatial and temporal variability of Escherichia coli (E. coli) concentrations and sources within and upstream of the Park. The supplemental data release includes stream-stage datasets collected by the USGS using pressure transducers and effluent-discharge and E. coli concentration data collected by the U.S. International Boundary and Water Commission.
E. coli and effluent-discharge: E. coli concentration and effluent-discharge data were collected by U.S. International Boundary and Water Commission at the Nogales International Wastewater Treatment Plant outfall (SC6, 312724110580501). The E. coli data at this site were collected for the period of June 1, 2009 to March 31, 2015 and effluent-discharge were collected for the period of Octorber 1, 2012 to Octorber 31, 2016.
Stream-stage:
The stream-stage data was collected at 10 locations using non-vented Solinst 3001 Leveloggers during the period of February, 2015 to December, 2016. The data were logged continuously at a 15-minute interval and manually downloaded. Non-vented pressure transducers do not correct for the atmospheric pressure, therefore, data were corrected for barometric pressure using a Solinst 3001 Barologger located in the gage house at the Santa Cruz River at Tubac location (SC14, 09481740). The Leveloggers were fastened to a metal stake within the stream channel or mounted to a bridge pier.
Stream-stage datasets and period of collection are provided for the following stations:

Purpose
This data supplement includes stream-stage data collected from 10 locations during the investigation period, unit-value effluent-discharge data from the U.S. International Boundary and Water Commission-Nogales International Wastewater Treatment Plant (IBWC-NIWTP) during water years 2012–2016, and E. coli data collected from the IBWC-NIWTP outfall during water years 2009–2014. These datasets are used in a Scientific Investigation Report that investigates E.coli concentrations and sources in TUMA and the contributing upper Santa Cruz Watershed.
