Groundwater Conditions in the Detrital Valley 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 4.3-5.  Figure 4.3-6 shows aquifer flow direction and water-level change between 1990-1991 and 2003-2004.  Figure 4.3-7 contains hydrographs for selected wells shown on Figure 4.3-6.  Figure 4.3-8 shows well yields in two 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 in Volume 1, Appendix A.  For more information on groundwater in the Detrital Basin click here.

Major Aquifers

  • Major aquifers in the basin include recent stream alluvium, basin fill and sedimentary rock.  The principal water-bearing aquifer is the basin fill.
  • Flow direction is generally from the south to the north.

Well Yields

  • As shown on Figure 4.3-8 well yields in this basin range from less than 100 gallons per minute (gpm) to 500 gpm.
  • One source of well yield information, based on six reported wells, indicates that the median well yield in this basin is 31.5 gpm.

Natural Recharge

  • Refer to Table 4.3-5.
  • The estimate of natural recharge for this basin is 1,000 acre-feet per year (AFA).

Water in Storage

  • Refer to Table 4.3-5.
  • Storage estimates for this basin range from 1.0 million acre-feet (maf) to 7.0 maf to a depth of 1,200 feet.

Water Level

  • Refer to Figure 4.3-6. Water levels are shown for wells measured in 2003-2004.
  • The Department annually measures 11 index wells in this basin. Hydrographs for two index wells (A and C) and one other well are shown in Figure 4.3-7.  More recent hydrographs of index wells may be available through the Department's GWSI database.
  • The Department measures water levels four times daily at one automated groundwater monitoring site in  the west-central portion of the basin.  
  • The deepest recorded water level in the basin is 597 feet west of Dolan Springs and the shallowest is 68 feet west of Temple Bar.
