Annual Streamflow Reconstructions for the Upper Colorado (UCRB) & Salt-Verde-Tonto (S+V+T)
River Basins

The current focus of this site is the use of streamflow reconstructions produced in conjunction with LTRR-SRP-I Project: A Tree-Ring Based Assessment  of Synchronous Extreme Streamflow Episodes in the Upper Colorado & Salt-Verde-Tonto  River Basins
                                      For more details, see the  LTRR-SRP-I Project Webpage

Note: new and updated results based on LTRR-SRP-II:  "The Current Drought in Context: A Tree-Ring Based Evaluation Of Water Supply Variability For The Salt-Verde River Basin"  will be added after public release.
