Major springs with discharge rates and date of measurement and the total number of springs in the basin are shown in Table 6.5-2.  The location of a major spring and perennial stream are shown on Figure 6.5-5.   Descriptions of data sources and methods for intermittent and perennial reaches and springs are found in Volume 1, Appendix A.

• There are no intermittent streams.  Perennial streams include the Colorado River and Boulder Wash.
• There is one major spring in the basin, Spring Canyon located at the Colorado River, with a discharge rate of 331 gallons per minute (gpm).
• Springs with measured discharge of 1 to 10 gpm are not mapped but coordinates are given in Table 6.5-2B.  There are five minor springs in this basin.
• The total number of springs, regardless of discharge, identified by the USGS varies from 51 to 56, depending on the database reference.
