Streamflow data, including average seasonal flow, average annual flow and other information is shown in Table 5.3-2. Flood ALERT equipment in the basin is shown in Table 5.3-3. Reservoir and stockpond data, including maximum storage or maximum surface area, are shown in Table 5.3-4. The location of streamflow gages identified by USGS number, flood ALERT equipment and USGS runoff contours are shown on Figure 5.3-5. 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 5.3.5 - 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.
Data from four stations located on two watercourses are shown in the table and on Figure 5.3-5.
The average seasonal flow at all stations is highest in the winter (January-March) and lowest in the summer (July-September).
The largest annual flow recorded is 469,256 acre-feet in 1978 at the Tonto Creek above Gun Creek near Roosevelt station and the smallest is 1,245 acre-feet in 1971 at the Rye Creek near Gisela station. For a hydrograph of Tonto Creek above Gun Creek near Roosevelt station from 1941-2008 see Figure 5.3-4.
Flood ALERT Equipment
- Refer to Table 5.3-3.
- As of October 2005 there were nine stations in the basin.
Reservoirs and Stockponds
- Refer to Table 5.3-4.
- The basin does not contain any large reservoirs.
- Surface water is stored or could be stored in one small reservoir in the basin.
- There are 389 registered stockponds in this basin.
Average annual runoff is two inches per year, or 106.6 acre-feet per square mile, in the southern tip of the basin and increases to five inches per year, or 266.5 acre-feet per square mile, in the northern portion of the basin.
