TreeFlow: Streamflow Reconstructions from Tree Rings

This site provides easy access to tree-ring reconstructions of streamflow and temperature in the United States. It includes information on how the data were developed and how they can be used. 

While the primary users of streamflow reconstructions are water resource professionals, people in several other sectors and disciplines may find the data useful. Users can acquire data and graphics to place historic variability and projected change in streamflows in a long-term paleo context.
