Major and minor springs with discharge rates and date of measurement, and the total number of springs in the basin are shown in Table 3.10-5.  The locations of major springs as well as perennial and intermittent streams are shown on Figure 3.10-5.   Descriptions of data sources and methods for intermittent and perennial reaches and springs are found in Volume 1, Appendix A. Additional information on surface water in this basin can be found in Section 3.10.4 - Surface Water Conditions and Section 3.0.2 - Surface Water Hydrology.

• There are numerous perennial stream reaches located primarily along the western boundary of the basin, as well as the San Carlos River and the Blue River in the northern part of the basin.

• Numerous intermittent streams occur primarily along the western boundary of the basin.

• The Gila River is predominantly an intermittent stream through the basin, with perennial reaches shown on Figure 3.10-6.

• There are 24 major springs with a measured discharge of 10 gallons per minute (gpm) or greater at any time. The largest discharge rate is 3,398 gpm at Warm Spring.  This is the largest recorded discharge in the planning area.

• Springs with measured discharge of 1 to 10 gpm are not mapped but coordinates are given in Table 3.10-5.  There are 30 minor springs identified in this basin.

• Listed discharge rates may not be indicative of current conditions.  Most of the measurements were taken prior to 1990 and many measurements date from the 1940’s and 1950’s.  Three major and two minor spring measurements post-date 1990.

• The total number of springs identified by the USGS varies from 379 to 387, depending on the database reference.
