Streamflow data, including average seasonal flow, average annual flow and other information is shown in Table 5.5-2.  Flood ALERT equipment and SRP low-flow gages in the basin are shown in Table 5.5-3.  Reservoir and stockpond data, including maximum storage or maximum surface area, are shown in Table 5.5-4.  The location of streamflow gages identified by USGS number, flood ALERT equipment, SRP gages, USGS runoff contours and large reservoirs are shown on Figure 5.3-4.  Additional information on surface water in this basin can be found in Section 5.5.5 - Perennial/Intermittent Streams and Springs and Section 5.0.5 - Surface Water Hydrology. Where available, the header for each section provides a link to the data web site. 

Streamflow Data

• Refer to Table 5.5-2.

• Data from 36 stations located at 22 watercourses are shown in the table and on Figure 5.5-4. 

• The average seasonal flow at all stations but one is highest in the winter (January-March) and lowest at most stations in the summer (July-September).

• The largest annual flow recorded is 1,583,014 acre-feet in 1993 at the Verde River below Tangle Creek above Horseshoe Dam station and the smallest was seven acre-feet in 1964 at the East Fork Sycamore Creek near Sunflower station

• Seventeen streams in this basin have a mean annual flow of over 10,000 acre-feet.  One river, Verde River, has a mean annual flow of over 100,000 acre-feet.

Flood ALERT Equipment

• Refer to Table 5.5-3.
• As of October 2005 there were 41 stations in the basin. 

Salt River Project (SRP) Low-Flow Gages

• Refer to Table 5.5-3a

• There are four SRP low-flow gages in this basin.  These gages are a project of SRP, Prescott National Forest and Arizona Game and Fish, designed to provide real-time information to the public about the Verde River streamflow.

Reservoirs and Stockponds

• Refer to Table 5.5-4.

• The basin contains 13 large reservoirs.  The largest, Bartlett, has a maximum storage of 178,186 acre-feet.

• Surface water is stored or could be stored in 59 small reservoirs in the basin.

• There are 2,328 registered stockponds in this basin.

Runoff Contour

• Refer to Figure 5.5-4.

• Average annual runoff is 0.1 inches per year, or 5.33 acre-feet per square mile, in the northwestern portion of the basin and 1 inch, or 53.3 acre-feet per square mile, in the southwestern portion of the basin.  Average annual runoff increases to five inches per year, or 266.5 acre-feet per square mile, in the west central portion of the basin.
