Graph of gaged and reconstructed streamflow

Gaged (blue) and reconstructed (green) records over the calibration/validation period (1916-1987).

 

Graph of reconstructed streamflow

Full reconstruction (1685-1987), 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.
