ApeLake
with a surface area of 247 km2 and an estimated volume of 85,5 Mio m3 has been dammed up for many centuries
by Fyles Glacier. Since the turn of the 19th century,
the ice terminus has been thinning and retreating. Thinning is probably the
primary cause of a j�kulhlaup which drained 45,8 Mio m3 of ApeLake
on October 20, 1984. The resultant flood had a peak discharge of 1`000 - 1`800
m3/s. There were heavy forestry and salmon fishing losses as well as
washed out roads, bridges and ocean navigational hazards (debris).
