This catalog has been prepared to summarize available information for selected springs and seeps in the Upper Queen Creek and Devils Canyon watersheds (UQC/DC). The springs and seeps included in this catalog were selected based on proximity to planned facilities as proposed by Resolution Copper (RC) for the Resolution mine project. The catalog was prepared by Montgomery & Associates (M&A) and WestLand Resources, Inc. (WRI) on behalf of RC.
As part of continuing biological resources support for Resolution’s GPO, WestLand conducted surveys for special-status plant species associated with water features that occur in the vicinity of the GPO (Study Area). The objective was to survey for special-status species with potential to occur in the Study Area, and to continue compiling baseline data on wetland and riparian plant species at a combination of lentic (ponds and stock tanks) and lotic (perennial and intermittent drainages, seeps, and springs) habitats (hereafter, “sites” and “reaches”, respectively).
This report presents a flood-duration flow frequency analysis for selected durations (1 day, 3 day, 7 day, 15 day, and 30 day) at 173 streamgaging stations throughout Arizona and in western New Mexico.
Flooding is among the worst natural disasters responsible for loss of life and property in Arizona, underscoring the importance of accurate estimation of flood magnitude for proper structural design and floodplain mapping. Twenty-four years of additional peak-flow data have been recorded since the last comprehensive regional flood frequency analysis conducted in Arizona. Periodically, flood frequency estimates and regional regression equations must be revised to maintain the accurate estimation of flood frequency and magnitude.

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.
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.
