Climate of the Lake Havasu Basin

Climate data from NOAA/NWS Co-op Network stations are complied in Table 4.5-1 and the location is shown on Figure 4.5-3.  Figure 4.5-3 also shows precipitation data from the Spatial Climate Analysis Service (SCAS) at Oregon State University. The Lake Havasu Basin does not contain Evaporation Pan, AZMET and SNOTEL/Snowcourse stations.  More detailed information on climate in the planning area is found in Section 4.0.3.  A description of the climate data sources and methods is found in Volume 1, Appendix A.  For a link to the web site for each climate data source click its header.
