Lake is located at 60 11' N 149 58' W, along the margin of a lobe of the
Harding Ice Field, east of the lobe labeled "Skilak Glacier". The water
drains subglacially into Skilak River.
Dump History (based on available information):
Jan. 1969 - occurred when the Kenai River had an ice cover; caused ice
jam flooding downriver from Skilak Lake. The river stage
at Soldotna was the highest ever recorded 22.62 ft, 1/18/69.
Sep. 1971 - inferred from a series of photos taken at the site from
7/21/71 to 9/10/71
Aug. 1974 - possible partial release; possibly along margin of glacier to
the southeast of the lake.
Sep. 1977 - observed in the process of dumping.
between 10/18/79 and 7/17/80 - based on overflights on those two dates.
Nov. 1985 - based on rise at Keys and Soldotna, but not Cooper Landing.
Nov. 1990 - we think. It occured coincident to a dump of the Snow River
glacier-dammed lake.
Jan. 1994 - observed at Keys; CAP overflight to verify
Oct. 1995 - observed at Keys; verified by RFC overflight
Oct. 1997 - began on about the 16th; observed at Keys
Nov. 1999 - began on about Oct 29th; observed at Keys and Soldotna
Nov. 2002 - release estimated to begin on or before November 23
Oct. 2004 - Release began on 22nd. Crested on 28th after 2 - 2.5 ft rise.
Jan. 2007 - release began on 16th; crested on 27th after 3.8 ft rise at Skilak
Lake; occurred when lower Kenai River had ice cover; caused ice jam
flooding from river mile 32 to below Big Eddy; the river stage at
Soldotna reached 20.00 ft, 1/28/07 when a jam formed 1/2 mile
downstream of the Sterling Hwy bridge
