Title: Networks of tree-ring based streamflow reconstructions for the Pacific Northwest: multi-century perspectives on regional hydroclimatic variability

Speaker: Jeremy Littell, Research Ecologist, USGS Alaska Climate Adaptation Science Center

Summary: Water resources planning in a climate change world can benefit from knowledge about the range of intrinsic hydroclimatic variability, which varies regionally with climate and watershed geography. In river basins like the Colorado or Missouri, networks of streamflow reconstructions from tree rings provide centuries of additional information about droughts and wet periods prior to consistent instrumentation. No such regional network existed in the Pacific Northwest (PNW). We will describe the development of and results from the first methodologically consistent network (36 gages, 500+ years) of hydroclimatic reconstructions for the Columbia and Snake River systems.
