BREAK-UP DATES

Lake Temagami 1985-2017

 

Recorded by Glen Toogood and others

Glen Toogood has lived on Lake Temagami for 23 years. Each spring he meticulously recorded break-up on the calendar. He dug the old dates out of boxes for us in 2005, and we update it annually. 

In 2009, we started using others, as Toogood moved off the lake.

The dates reflect what he observed from his central lake location. Break-up across the entire lake may have extended another day or two. Clearly, not an exact science. Since the Toogood era we now use multiple observers around the lake and do a whole-lake estimation.

Lake Temagami as one of the deepest lakes is usually the last to go. The North Arm within the lake, particularly between Rabbitnose and Devil's Island, is usually the last section. The best locations to record complete break-up is at Devil's, Narrows or Garden islands. Temagami Bay tends to go earlier than most of the lake.

Has there been a change over the decades? At the end of the 19th century, explorer A.E. Barlow with the Geological Survey of Canada noted that break-up was usually by May 24.

  Freeze-up dates

* Was this a record?

** May 4 was orignally reported as ice-out after observations from Devil's Island and a boat run up the North Arm to Sharp Rock. The North Arm is often the last holdout. However, on May 6, Bob Farr found a fading ice flow between Ogama, Moore and Temagami islands. Experience makes this an unusual spot for remnant ice and Farr suspects it may have drifted from Cattle Island, a more likely holdout location. Making the ice-out call is an estimation from local experience and can only be done with absolute confidence by a low flyover or a comprehensive boat run, which we have never had.

** April 29 was orignally reported as ice-out after observations from Devil's Island and Witch's Point. A boat run up the North Arm to Sharp Rock by Owen Bateman found the last holdout at Horseshoe Island that took two more days to go. Bateman still got to Sharp Rock through the Lower Narrows.
