Streamflow was not measured in this basin.  Flood ALERT equipment in the basin is shown in Table 4.4-1.  Reservoir and stockpond data, including maximum storage or maximum surface area, are shown in Table 4.4-2.   The location of flood ALERT equipment, USGS runoff contours and large reservoirs are shown on Figure 4.4-4.  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 4.4.5 - Perennial/ Intermittent Streams and Springs and Section 4.0.2 - Surface Water Hydrology. Where available, the header for each section provides a link to the data web site.  

Flood ALERT Equipment

• Refer to Table 4.4-1.
• As of October 2005 there were six stations in the basin.

Reservoirs and Stockponds

• Refer to Table 4.4-2.

• The basin borders one large reservoir, Lake Mead, with a maximum capacity of 29,755,000 acre-feet.  The dam that creates Lake Mead, Hoover Dam, is in the Lake Mohave Basin.

• Other large reservoirs in the basin include Red Lake with a maximum surface area of 13,412 acres.  Red Lake is a dry lake and its use is unknown.

• Surface water is stored or could be stored in two small reservoirs in the basin.

• There are 72 registered stockponds in this basin.

Runoff Contour

• Refer to Figure 4.4-4.

• Average annual runoff is 0.5 inches per year, or 26.65 acre-feet per square mile, in the southwest corner of the basin around New Kingman-Butler and decreases to 0.1 inches, or 5.33 acre-feet per square mile, in the center of the basin.
