Groundwater Conditions in the Meadview 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 4.7-5.  Figure 4.7-6 shows aquifer flow direction and water-level change between 1990-1991 and 2003-2004.  Figure 4.7-7 contains a hydrograph for a selected well shown on Figure 4.7-6.  Figure 4.7-8 shows well yields in one yield category.  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. 

Major Aquifers

  • Refer to Table 4.7-5 and Figure 4.7-6.
  • The major aquifer in this basin is sedimentary rock, Muddy Creek Formation.
  • Flow direction is from the south to the north in this basin.

Well Yields

  • Refer to Table 4.7-5 and Figure 4.7-8.
  • As shown on Figure 4.7-8 well yields in this basin are less than 100 gpm.
  • One source of well yield information, based on five reported wells, indicates that the median well yield in this basin is 33 gpm.

Natural Recharge

  • Refer to Table 4.7-5.
  • The estimate of natural recharge for this basin is 4,000 acre-feet per year (AFA).
  • Recharge in this basin is minimal because of high evaporation rates and low rainfall.  Most of the basin’s recharge comes from infiltration of runoff at higher elevations surrounding the basin.

Water in Storage

  • Refer to Table 4.7-5.
  • Storage estimates for this basin range from 62,440 acre-feet to a depth of 700 feet to 1.0 million acre-feet to a depth of 1,200 feet. 

Water Level

  • Refer to Figure 4.7-6. Water level is shown for wells measured in 2003-2004.
  • The Department annually measures one index well in this basin. A hydrograph for this well is shown in Figure 4.7-7.
  • The Department measures water levels four times daily at one automated ground water monitoring site in  the west-central portion of the basin.  
  • There are only three water depths recorded in this basin in 2003-2004.  In these wells, the deepest is 931 feet in the southern portion of the basin along Pierce Ferry Road and the shallowest is 134 northeast of Meadview.
