Surface Water Conditions in the Duncan Valley Basin

Streamflow data, including average seasonal flow, average annual flow and other information is shown in Table 3.7-2.  Flood ALERT equipment in the basin is shown on Table 3.7-3.  Reservoir and stockpond data, including maximum storage or maximum surface area of large reservoirs and type of use of the stored water, are shown in Table 3.7-4.   The location of streamflow gages identified by USGS number, flood ALERT equipment, USGS runoff contours and large reservoirs are shown on Figure 3.7-4.  Descriptions of stream, reservoir and stockpond data sources and methods are found in Volume 1, Appendix A.  Additional information on surface water in this basin can be found in Section 3.7.5 - Perennial/Intermittent Streams and Springs and Section 3.0.2 - Surface Water Hydrology. Where available, the header for each section provides a link to the data web site.  

Streamflow Data

  • Refer to Table 3.7-2.
  • Data from two real-time stations located at the Gila River are shown on the table and on Figure 3.7-4.

  • As of 2005 only the Gila River near Clifton station had more than three years of annual flow record.  At this station, maximum annual flow was 480,118 acre-feet in 1915 and minimum annual flow was 17,670 acre-feet in 1956.  Average seasonal flow is highest in the Winter (January-March) and lowest in the Spring (April-June).

Flood ALERT Equipment

  • Refer to Table 3.7-3.
  • There is one station in the basin as of October 2005. 

Reservoirs and Stockponds

  • Refer to Table 3.7-4.
  • There is one large reservoir and two small reservoirs in this basin.

  • The large reservoir has a maximum surface area of 124 acres.  This reservoir is used for fire protection or is a stock/farm pond.

  • There are 373 registered stockponds in this basin.

Runoff Contour

  • Refer to Figure 3.7-4.
  • Average annual runoff varies from 0.5 inches, or 26.65 acre-feet per square mile, at the northern tip of the basin to 0.2 inches, or 10.66 acre-feet per square mile, in the southern portion of the basin.
