I've been thinking about going down the Back River, and I'd like to do it in as many days as possible. So I need some information about when, approximately, the ice breaks in that area?

Also, were can we get maps of the river?

Hope someone can provide me with some information.

The ice can be late leaving some years.
Last summer we did the Thelon, which is a south of the Back, and the lakes were still frozen over solid the last week of June. The river itself however was accessible with very high and fast water at that date.
Most people fly in no earlier than very late June/early July.
For maps you can buy from this site:

Go her for Back River info and contacts:

This is not an easy river from what I’ve read. Needs lots of preparation.
Good luck,

Consider remote sensing.

Satellite photos, specifically the Terra-1/MODIS sensor, show breakup
in the bigger lakes.

I use the swath viewer at http://sv.gina.alaska.edu which covers
alaska and northwest canada. Maximum resolution is 1 km per pixel.
The java applet is slow, memory intensive, and buggy. But it does
work. Ice and clouds look white and water and land are black.

On June 11 2004 18:44:52 GMT, for example, the clear weather shows
the ice in Great Bear Lake completely filling the lake. Another
good photo on June 30 2004 20:52:31 GMT shows cracks in the ice,
and on July 11 2004 20:34:12 GMT the ice is nearly gone.

I have not done any ground truthing to find whether a lack of lake
ice in the photo implies a total absence of ice in the lake.

Ice goes out on Baker Lake proper the beginning of the second week of July. Pelly and Garry Lakes on the Back River might be later. Coming up the Meadowbank to the Thelon will put you in Baker Lake in August--makes for an easier trip going home on the airlines than continuing to Gjoa Haven. The last kayaker we rescued off Garry Lake on the Back River had triggered an ELT when he couldn't find the egress from the lake. Didn't have a GPS. Didn't have a good compass. Didn't have good maps. Didn't have a good kayak (Klepper with lots of patched holes in the skin). Needless to say the SARTech's (Search and Rescue Technicians) on the Herc CC-130 were not amused. The guy had to get his German relatives to pay to get him extracted by civil helicopter. I ended up with the frame and am still looking for a newer skin.
