Surface Water Conditions in the Virgin River Basin

Streamflow data, including average seasonal flow, average annual flow and other information are shown in Table 6.6-2.  Flood ALERT equipment in the basin is shown in Table 6.6-3.  Reservoir and stockpond data, including maximum storage or maximum surface area, are shown in Table 6.6-4. The location of streamflow gages identified by USGS number, flood ALERT equipment, USGS runoff contours and large reservoirs are shown on Figure 6.6-5.  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 6.6.5 - Perennial/Intermittent Streams and Springs and Section 6.0.2 - Surface Water Hydrology. Where available, the header for each section provides a link to the data web site.

Streamflow Data

  • Refer to Table 6.6-2.
  • Data from three real-time stations located at two watercourses are shown in the table and on Figure 6.6-5. 

  • In general, average seasonal flow is highest in the winter (January-March). 

  • The maximum annual flow was 597,522 acre-feet in 2005 at the Virgin River at Littlefield station with a contributing drainage area of 5,090 square miles.  This annual flow is not shown on Table 6.6-2 because the statistics are current as of December 2004. 

  • Figure 6.6-4 shows the periodic flood events in the Virgin River recorded at the Littlefield gage from 1930-2006.

Flood ALERT Equipment

  • Refer to Table 6.6-3.
  • As of October 2005 there was one station in the basin.  

Reservoirs and Stockponds

  • Refer to Table 6.6-4.
  • There are no large reservoirs and one small reservoir with a total surface area of six acres.
  • There are 45 registered stockponds in the basin.

Runoff Contour

  • Refer to Figure 6.6-5.
  • Average annual runoff is highest, 0.5 inches per year or 26.65 acre-feet per square mile, at the southeastern tip of the basin and decreases to 0.1 inches, or 5.33 acre-feet per square mile, to the north and west.
