Graph of gaged and reconstructed streamflow

Gaged (blue) and reconstructed (green) records over the calibration/validation period (1922-1999).

 

Graph of reconstructed streamflow

Full reconstruction (1571-1999), with annual values (green) and a 5-year weighted mean.

 

Graph of sample depth

Total sample depth (typically, two series per tree) for the reconstruction.
