TreeFlow - about us

Jeff Lukas is a Professional Scientist with the Institute of Arctic and Alpine Research (INSTAAR) at the University of Colorado, Boulder, where he manages the INSTAAR Dendrochronology Lab. Jeff has been involved with tree-ring research since 1998, and has been working with water managers to develop tree-ring reconstructions of streamflow since 2002.

Connie Woodhouse is Associate Professor in the Department of Geography and Regional Development at the University of Arizona in Tucson, AZ. From 1998 to 2006, she was a Physical Scientist in the Paleoclimatology Branch of NOAA's National Climatic Data Center in Boulder, CO. She has been involved with tree-ring research since the late 1980s, and has been working with water managers on reconstructions of streamflow since 1998.

A Brief History

In the late 1990s, Connie began to explore the feasibility of reconstructing precipitation and streamflow from existing tree-ring chronologies in Colorado's Front Range. The initial results were promising and she recognized that they could be improved with additional tree-ring collections in the Front Range, and also in western Colorado, where few tree-ring chronologies had been developed since the 1960s. Starting in summer 2000, she and Jeff began systematically updating existing collections and collecting new data at tree-ring sites across Colorado, for the purpose of developing new hydroclimatic (precipitation, streamflow, drought) reconstructions. In spring 2002, Connie and Robert S. (Robin) Webb of NOAA-ESRL received a multi-year grant from NOAA's Office of Global Programs, entitled "Extended Hydroclimatic Records for the Upper Colorado River Basin", to work with water managers to use this growing network of tree-ring chronologies to develop hydroclimatic reconstructions. Partnerships with several water entities resulted in over 20 reconstructions of streamflow for Colorado, made accessible through the TreeFlow website housed at NOAA Paleo. A concurrent research effort by Connie with Stephen Gray (USGS, now Wyoming State Climatologist) and David Meko (U. of Arizona) generated 10 new reconstructions for the Upper Colorado River Basin.

WWA has funded and supported Connie and Jeff's work on streamflow reconstructions since 2004, with a focus on making these data more useful and accessible to water resource managers. Recent and ongoing efforts include the presentation of technical workshops, the development of new web resources, and the development of additional reconstructions for basins in Colorado and adjacent states.
