Thanks for searching db & st. Now I feel less of a techno misfit. None of those links is the document for which I search. The only clue I have on date is that it is in update from a table dated in 2000, making it this century. I recounted the pages and it is only 9 pages, not 10. I wish I had the info regarding title, author, date, that you seek. It covers 298 lakes in Quetico.

MP, I assume that your fishfinder will locate whitefish. My point in saying that they stay near the bottom was that a few years ago, I read a huge cloud of baitfish about mid-lake over deep water (over 100') and mistakenly thought it might be whitefish. Apparently not, I didn't catch any. According to what I read, they were most likely herring or possibly ciscoes.

I'm a novice with whitefish, but would suggest smaller lure sizes (small mouths) with lots of flash. Deep jigging on or near the bottom of deep holes would probably be productive. As has been pointed out, they are excellent eating. 8-)
