Cultural Water Demands in the Tonto Creek Basin

Cultural water demand data including population, number of wells and the average well pumpage and surface water diversions by the municipal, industrial and agricultural sectors are shown in Table 5.3-8.  Effluent generation including facility ownership, location, population served and not served, volume treated, disposal method and treatment level is shown in Table 5.3-9.  Figure 5.3-11 shows the location of demand centers. A description of cultural water demand data sources and methods is found in Volume 1, Appendix A.  More detailed information on cultural water demands is found in Section 5.0.7.  For information on gpcd and annual water demand by individual community water systems in this basin see ADWR's Community Water System Program annual water use reporting summary.

Cultural Water Demands

  • Population in this basin has increased from 1,934 in 1980 to 7,975 in 2000.

  • Groundwater use has fluctuated from a low of 2,000 AFA in the 1970s to an average of 4,000 AFA from 1986-1990. During 2001-2005 the average annual groundwater demand was 3,050 AFA.

  • Municipal groundwater use has increased from an average of 1,600 AFA in 1991-1995 to 2,400 AFA in 2001-2005.

  • There was no reported industrial groundwater use in 1991-1995.  In 2001-2005, industrial demand was less than 300 AFA.

  • Groundwater demand for irrigation was less than 1,000 AFA during 1991-2005.

  • Information on surface water diversions is not available from 1971-1990.  From 1991-2005, 1,000 AFA was used for irrigation.

  • Municipal and industrial demand is principally found in the vicinity of Payson and Star Valley with smaller demand centers scattered along State Highways 188 and 260 as well as east of Rye.

  • A small amount of agriculture is located east of Rye and in T9N, R10E.

  • There is one small mine or quarry in this basin along Highway 87 south of Payson.

  • As of 2005 there were 1,948 registered wells with a pumping capacity of less than or equal to 35 gpm and 280 wells with a pumping capacity of more than 35 gpm.

Effluent Generation

  • Refer to Table 5.3-9.
  • There are three wastewater treatment facilities in this basin. Data on population served, volume treated and disposal method was only available for one facility.  This facility serves approximately 100 people, generates 13 acre-feet of effluent each year and discharges to Houston Creek.
