Abstract

Sediments in eight glacier-fed lakes of the southern Canadian Cordillera have been investigated. Laminated or varved sediments are used to construct accumulation chronologies which reflect both average and extreme depositional regimes. An average of 4-6 extreme events per 100 years appears to be common in these lakes; however, their low frequency suggests sediment delivery is dominated by the average regime. Reconstructions of specific sediment yield are in the range of 30-450 t km "SUP -2" year "SUP -1" averaged over the last 140 years. Long-term declines are related to increased storage and sediment exhaustion in the upper basins
