Major and minor springs with discharge rates and date of measurement, and the total number of springs in the basin are shown in Table 7.10-3.  The location of a major spring is shown on Figure 7.10-5.   There are no perennial or intermittent streams in the Western Mexican Drainage Basin.  Descriptions of data sources and methods for intermittent and perennial reaches and springs are found in Volume 1, Appendix A.

• There is one major spring with a measured discharge rate of 28 gallons per minute (gpm).  This discharge rate may not be indicative of current conditions; the spring was last measured during or prior to 1992.   This is the only major spring in the planning area.
• Springs with measured discharge of 1 to 10 gpm are not mapped but coordinates are given in Table 7.10-3B.  There are two minor springs in this basin.
• The total number of springs, regardless of discharge, identified by the USGS varies from four to six, depending on the database reference.
