Tree-ring-based reconstructions of paleo-hydrology have proved useful for better understanding the irregularities and extent of past
climate changes, and therefore, for more effective water resources management. Despite considerable advances in the field, there
still exist challenges that introduce significant uncertainties into paleo-reconstructions. This study outlines these challenges and
address them by developing two themes: (1) the effect of temporal scaling on the strength of the relationship between the hydrologic
variables, streamflow in this study, and tree growth rates and (2) the reconstruction uncertainty of streamflow due to the dissimilarity
or inconsistency in the pool of tree-ring chronologies (predictors in reconstruction) in a basin.
