Climate data from NOAA/NWS Co-op Network and Evaporation Pan stations are complied in Table 3.6-1 and their locations are shown on Figure 3.6-3.  Figure 3.6-3 also shows precipitation contour data from the Spatial Climate Analysis Service (SCAS) at Oregon State University.  The Dripping Springs Wash Basin does not contain AZMET and SNOTEL/Snowcourse stations.  More detailed information on climate in the planning area is found in Section 3.0.3.  A description of the climate data sources and methods is found in Volume 1, Appendix A.

NOAA/NWS Co-op Network

• Refer to Table 3.6-1A
• There is one NOAA/NWS Coop network climate station in the basin at San Carlos Reservoir.  The average monthly maximum temperature is 86.6°F and average minimum temperature is 46.4°F.
• Winter, summer and fall season precipitation is relatively similar; 5.36 inches, 5.07 inches and 4.36 inches respectively. 
• The dry season is in the spring (April-June) when an average of 1.08 inches is recorded.

Evaporation Pan

• Refer to Table 3.6-1B

• There is one site in the basin at San Carlos Reservoir, located at 2,530 feet with an average annual evaporation of 91.45 inches.

SCAS Precipitation Data

• See Figure 3.6-3

• Other precipitation data shows rainfall as high as 30 inches at the northernmost tip of the basin in the Pinal Mountains, and as low as 12 inches in the vicinity of Christmas.
