Abstract
Ice floods occurring at the time of spring break-up were reconstructed for Lake Duparquet, a large unregulated water body located at the southern fringe of the boreal forest in north-western Quebec (Tardif and Bergeron 1997). Reconstruction of the frequency and magnitude of spring floods associated with ice break-up was successfully achieved using cross-dating of ice-scars occurring along the trunk of northern white-cedar (Thuja occidentalis) trees exposed to drifting ice and debris during ice break-up. Maximum ice-scar height was also used as an indicator of high lake water level. Ice-scarred trees were systematically sampled on the islands and lake shore. A total of 81 T. occidentalis trees were collected resulting in 253 cross-sections and over 2,000 dated scars associated with 616 scarring events.
