Major and minor springs with discharge rates and date of measurement, and the total number of springs in the basin are shown in Table 4.1-5.  The locations of major springs as well as perennial and intermittent streams are shown on Figure 4.1-5.   Descriptions of data sources and methods for intermittent and perennial reaches and springs are found in Volume 1, Appendix A.

• There are five perennial streams located in the basin, Cottonwood Creek, Willow Creek, Fort Rock Creek, Trout Creek and the Big Sandy River.

• Numerous intermittent streams are located throughout the basin with a relatively large emanating from the western basin boundary.

• There are six major springs with a measured discharge of 10 gallons per minute (gpm) or greater at any time.  The largest discharge is 1,600 gpm at an unnamed spring near the Big Sandy River south of Cane Springs. 

• Springs with measured discharge of 1 to 10 gpm are not mapped but coordinates are given in Table 4.1-5B.  There are 11 minor springs identified in this basin.

• Listed discharge rates may not be indicative of current conditions.  All of the measurements were taken during or prior to 1982. 

• The total number of springs identified by the USGS varies from 165 to 179, depending on the database reference.
