Water Resources

This catalog has been prepared to summarize available information for selected springs and seeps in the Upper Queen Creek and Devils Canyon watersheds. The springs and seeps included in this catalog were selected based on proximity to planned facilities as proposed by Resolution Copper for the Resolution mine project. Version 2.0.

Surveys were conducted for special-status plant species associated with water features that occur in the vicinity of the Study Area.

Fourteen sites were studied to provide baseline technical hydrologic monitoring in the Oak Flat area within or adjacent to the projected disturbance zone of the proposed RC block cave mine.

Computed flood flow frequency and volume‐duration‐frequency values for points of interest on Queen Creek and Devil’s Canyon.

The principal objective of this report is to present and review groundwater level and hydraulic head data for the RC hydrologic monitoring network.

A series of stream gauges is located within the upper Queen Creek, Devil’s Canyon, and Mineral Creek watersheds, located near Superior, AZ. These gauges are owned and maintained by Resolution Copper Mining (RCM). The historical stream gauge records were analyzed by JE Fuller Hydrology & Geomorphology, Inc in order provide an assessment of the quantity and quality of the surface water data. These data were also used to characterize and quantify volumetric surface water discharge characteristics in the three watersheds.

This report is an addendum to the Surface Water Baseline Report prepared by M&A (2013) that includes detailed analysis and discussion of surface water monitoring results in the Resolution Project study area; Devils Canyon, Queen Creek, and Mineral Creek.

This report is an addendum to several previous reports that include detailed analysis and discussion of hydrochemical sampling results for surface water and groundwater in the Upper Queen Creek/Devils Canyon (QCDC) study area.

Hydrologic test wells HRES-01, HRES-02, HRES-03, HRES-04, and HRES-05 were drilled and constructed during the period February 2 to March 11, 2004. The test wells were drilled evaluate lithologic and hydrogeologic conditions within the Apache Leap Tuff, and were terminated in the uppermost part of the Whitetail Conglomerate. Final test well construction was designed to permit hydrologic testing of the Apache Leap Tuff aquifer, and to provide access for long-term monitoring of groundwater level and groundwater quality for the aquifer.
