Water Adequacy Determinations in the Yuma Basin

Water adequacy determination information including the subdivision name, location, number of lots, adequacy determination, reason for an inadequacy determination, date of determination and subdivision water provider are shown in Table 7.11-9A and B for water reports and analysis of adequate water supply.  Designated water provider information is shown in Table 7.11-9C with date of application, date the designation was issued and projected or annual estimated demand.  Figure 7.11-12 shows the general locations of subdivisions (to the section level) and designated providers keyed to the Table.  A description of the Water Adequacy Program is found in Volume 1, Appendix C.  Adequacy determination data sources and methods are found in Volume 1, Appendix A.

  • All subdivisions receiving an adequacy determination are in Yuma County.  Two hundred and sixty-two water adequacy determinations for 29,264 lots have been made in this basin through December 2008.  Twenty-seven thousand, five hundred and twenty-three lots in 241 subdivisions, or 94% of lots, were determined to be adequate.
  • The most common reason for a determination of inadequacy was because the applicant chose not to submit necessary information and/or available hydrologic data were insufficient to make a determination.
  • There is one analysis of adequate water supply for 54 lots.
  • There is one designated provider, City of Yuma.  The designation does not have a projected or annual estimated demand.
