Abstract:
Tree-ring reconstructed water level of Lake Athabasca at Ft. Chipewyan, Alberta Province, Canada. Reconstructed variable is the 10-day-average water level for the period July 11-20. Supplementary information can be found in the Meko (2002) BC Hydro report at: ftp://ftp.ncdc.noaa.gov/pub/data/paleo/treering/reconstructions/northamerica/ca nada/meko2002.pdf This report summarizes a tree-ring study of hydrologic variation in the Peace-Athabasca Delta. The study began with field collections of tree ring samples from the delta in late July, 2001. Ring widths and stable isotopes of carbon and oxygen in wood cellulose of rings were analyzed for hydrologic information. The initial objective was reconstruction of interannual variations in Lake Athabasca water level for the past 200 years. The study was later expanded to incorporate a larger network of existing tree-ring chronologies from western Canada and include reconstruction of streamflow of the Peace and Athabasca Rivers. Tree rings of white spruce (Picea glauca) have previously been used to reconstruct annual variations in Lake Athabasca water level back to the early 1800s (Stockton and Fritts 1973). This study includes an updated reconstruction of Lake Athabasca water level, and extends the earlier tree-ring work in several ways: 1) improved tree-ring site coverage of the delta with additional chronologies, 2) increased sample depth at existing tree-ring chronologies, 3) analysis of the statistical relationship between tree-ring indices and climatic, 4) analysis of stable-isotope variations in cellulose of tree rings, 5) placement of the delta chronologies in the context of tree-ring variations over a much larger region of western Canada, 6) reconstruction of annual streamflow of the Peace and Athabasca Rivers, and 7) statistical testing of differences in tree-ring data and reconstructed water-level before and after construction of W.A.C. Bennett Dam. Key data used in the study are listed in a series of appendices. Tree ring data available from the International Tree Ring Data Bank: http://www.ncdc.noaa.gov/paleo/treering.html Files cana212.rwl - cana219.rwl were used for the reconstruction. These data include 1970 collections by Fritts and Stockton, and new 2001 collections or recollections by Meko: cana212.rwl - Point Providence 2001 Recollection cana213.rwl - Quatre Fourches 2001 Recollection cana214.rwl - Horseshoe Slough cana215.rwl - Revillon Coupe 2001 Recollection cana216.rwl - Peace/Rouchers 2001 Recollection cana217.rwl - Athabasca River 2001 Recollection cana218.rwl - Birch River cana219.rwl - Mamawi Lake See Meko (2002) for details.
