Abstract: The Bear River contributes more water to the eastern Great Basin than any other river 21! system. It is also the most significant source of water for the burgeoning Wasatch Front 22! metropolitan area in Northern Utah. Despite its importance for water resources for the region’s 23! agricultural, urban, and wildlife needs, our understanding of the variability of Bear River’s 24! stream flow derives entirely from the short instrumental record (1943-2010). Here we present a 25! 1,200-year calibrated and verified tree-ring reconstruction of stream flow for the Bear River that 26! explains 67% of the variance of the instrumental record over the period from 1943-2010.
