Major and minor springs with discharge rates and date of measurement, and the total number of springs in the basin are shown in Table 4.2-5.  The locations of major springs as well as perennial and intermittent streams are shown on Figure 4.2-5.   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 4.2.4 - Surface Water Conditions and Section 4.0.2 - Surface Water Hydrology.

• Numerous intermittent streams are  located throughout the basin with the largest concentration in the northeastern portion of the basin.

• There are six major springs with a measured discharge of 10 gallons per minute (gpm) or greater at any time.  The largest discharge is 228 gpm at Genung spring.

• Springs with measured discharge of 1 to 10 gpm are not mapped but coordinates are given in Table 4.2-5B.  There are 13 minor springs identified in this basin.

• Listed discharge rates may not be indicative of current conditions.  All of the measurements were taken prior to 1983. 

• The total number of springs identified by the USGS varies from 249 to 303, depending on the database reference.
