Thanks for the reminder about Mallory Burton. I actually have a copy of her book called Reading the Water. I'll have to read it again.
The most recent fishing related books I picked up that I have not yet read, but are next on my list, are Beneath the Rising Mist by Dana Lamb, Running Waters by Datus Proper, and Remembering Dud Dean (a collection of Arthur Macdougall's Dud Dean stories, compiled by the late author's son Walter Macdougall).
