Selected research papers, reports, and other resources which show the current state-of-knowledge and the progress in our understanding of the variability of climate and hydrology in the Colorado River Basin and the potential impacts of future climate change.
Paleoclimatic (Tree-ring) Reconstructions
The TreeFlow web resource developed and maintained by WWA and CLIMAS provides tree-ring reconstructions of annual streamflow for over 60 gages across the U.S., over 30 of which are within Colorado, Utah, and Wyoming. It also has links to tree-ring reconstructions of precipitation, drought indices, and snowpack.
Long-Term Surface-Water Supply and Streamflow Trends in the Upper Colorado River Basin Based on Tree-Ring Analysis (1976) by C.W. Stockton and G.C. Jacoby. The first "modern" tree-ring reconstructions of streamflow in the Upper Colorado River Basin, while superseded by later work, is still a landmark in our understanding of the hydrologic history of the basin.
