| Contents Notes |
This report summarizes 10 yesr of ice cover observations (1971-81) for 12 stations along the international section of the St. Lawrence River. For each station and season, the tables list date of freeze-over, date ice free, duration of solid ice cover, maximum ice thickness, and date of maximum ice thickness. Mean dates of freeze-over range from January 1 to January 17, while mean dates of ice free conditions range from February 25 to March 23. The longest mean ice cover duration is 79 days and the shortest is 48 days. The mean maximum ice thickness varies between 23 cm and 56 cm. The mean date of this maximum is as early as February 9 and as late as March 5. Observations were taken during a period that contained 5 winters colder than normal and 5 winters warmer than normal, when compared to an 80-year record of air temperature. |
