Groundwater Conditions in the Aravaipa Canyon Basin

Major aquifers, well yields, estimated natural recharge, estimated water in storage, number of index wells and date of last water-level sweep are shown in Table 3.1-3   Figure 3.1-6 shows aquifer flow direction and water-level change between 1990-1991 and 2003-2004. Figure 3.1-7 contains hydrographs for selected wells shown on Figure 3.1-6. Figure 3.1-8 shows well yields in four yield categories.  A description of aquifer data sources and methods as well as well data sources and methods, including water-level changes and well yields are found here.  For more information on groundwater in the basin see Aravaipa Canyon Basin Hydrology.

Major Aquifers

  • Refer to Table 3.1-3 and Figure 3.1-6.
  • Major aquifers in the basin are recent stream alluvium and basin fill.
  • The recent stream alluvium is the primary source of groundwater in the basin.
  • Flow direction is generally from southeast to northwest.

Well Yields

  • As shown on Figure 3.1-8 well yields in this basin range from less than 100 gallons per minute (gpm) to 2,000 gpm.
  • One source of well yield information, based on 36 reported wells, indicates that the median well yield in this basin is 350 gpm.
  • The highest reported well yields in the basin are located in unconsolidated sediments in the vicinity of the Klondyke and Klondyke-Bonita Roads.

Natural Recharge

  • Refer to Table 3.1-3.
  • Natural recharge estimates range from 7,000 acre-feet per year (AFA) to 16,700 AFA.

Water in Storage

  • Refer to Table 3.1-3.
  • Storage estimates for this basin range from 5.0 million acre-feet (maf) to 5.1 maf to a depth of 1,200 feet. 

Water Level

  • Refer to Figure 3.1-6.  Water levels are shown for wells measured in 2003-2004.
  • The Department annually measures three index wells in this basin.  Hydrographs for these three wells are shown in Figure 3.1-7.  More recent hydrographs of the index wells may be available through the Department's GWSI webpage.
  • There are two wells with water depth reported in 2003-2004.  The wells are located along the Klondyke and Klondyke-Bonita Roads and measure 39 feet and 64 feet to water.
