Major and minor springs with discharge rates and date of measurement, and the total number of springs in the AMA are shown in Table 8.5-5. The locations of major springs and perennial and intermittent streams are shown on Figure 8.5-5. A description of data sources and methods for intermittent and perennial reaches and spring are found in Volume 1, Appendix A.
- Perennial streams include Romero Canyon, Sabino Canyon, Cienega Creek and Sycamore Canyon. An approximately 9-mile effluent-dependent reach of the Santa Cruz River is perennial due to discharges from the Roger and Ina Road WWTPs.
- Intermittent streams include stream segments near the eastern AMA boundary and in Santa Cruz County.
- There are eight major springs with a measured discharge of 10 gallons per minute (gpm) or greater at any time.
- Springs with measured discharge of 1 to 10 gpm are not mapped but coordinates are given in Table 8.5-5B. There are two minor springs.
- Listed discharge rates may not be indicative of current conditions. Measurement dates are not available for six springs and the remainder were measured during or prior to 1982.
- The total number of springs, regardless of discharge, identified by the USGS or ALRIS varies from 162 to 187, depending on the database reference.
