TAKU RIVER FLOOD 2004 - 45.07 ft
Glacier-lake-outburst floods originating from two glacier-dammed lakes along the margin of the Tulsequah Glacier in British Columbia, Canada,
are the source of the greatest peak discharges on the Taku River.
The largest flood during the period of record was 128,000 cubic feet per second on June 25, 2004,
resulting from an outburst of Lake No Lake. Lake No Lake is the larger of the two lakes.
The outburst-flood contribution to peak discharge was 80,000 cubic feet per second. The volume discharged from Lake No Lake is
relatively consistent indicating drainage may be triggered when the lake reaches a critical stage.
This suggests prediction of the timing of these outburst floods might be possible if lake-stage data were available.
Further increases in the volume of Lake No Lake are unlikely as all tributary glaciers have retreated out of the lake basin.
Decreasing outburst-flood volumes from Tulsequah Lake suggests a continued decline in the volume of this lake.
