Cultural Water Demand in the Detrital Valley 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 4.3-7.  Effluent generation including facility ownership, location, population served and not served, volume treated, disposal method and treatment level is shown in Table 4.3-8.  Figure 4.3-10 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 4.0.7.  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 is small but has almost doubled since 1980, increasing from 757 in 1980 to 1,373 in 2000.  Projections suggest a similar rate of growth through 2030, although large developments are

  • Groundwater pumping is minimal in this basin. Current pumping is comparable to historic pumping with an annual average of less than 300 AFA for municipal use from 2001-2005.  There are no recorded industrial or agricultural water demands in this basin.   There is, however, a small mine or quarry north of Grasshopper Junction.

  • All of the surface water diversions are for municipal use at Temple Bar within the Lake Mead National Recreation Area and are less than 300 AFA from 1991-2005.

  • Most municipal and industrial demand is around Dolan Springs at this time.  There are, however, a number of proposed residential developments in this basin east of Highway 93 and north of Pierce Ferry Road.

  • As of 2005 there were 168 registered wells with a pumping capacity of less than or equal to 35 gpm and 50 wells with a pumping capacity of more than 35 gpm.

Effluent Generation

  • Refer to Table 4.3-8.
  • There is one wastewater treatment facility, the Temple Bar Wastewater Treatment Facility, located within the Lake Mead National Recreation Area.

  • No other information on this facility was available.
