Lake Athabasca Water Level ReconstructionEntry ID: NOAA_NCDC_PALEO_2006-059
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

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
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
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:
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:
