Recently, I spoke to Lakis Polycarpou from Columbia University about my trip to
Bozeman, MT for an NSF project meeting on Paleo reconstruction of river discharges using tree rings for the Missouri River basin. Reconstruction of discharge from tree rings spanning past several centuries can provide a more complete picture of the range of variability (the deviation from average conditions) of the flows in the river at decadal to longer time scales. This proxy information (long history of flows) can be used to evaluate how good the current water policies are in the context of history. Here is the link to his article on our discussion.
treeflow.info is a very useful resource on tree rings, climate and water management.
For the more modeling-saavy, you can read my article on streamflow reconstruction using tree rings for the New York City reservoirs.
