Skilak Glacier Dammed Lake Dump History

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
