Reading the water

[mozkaynak]

Hi,
I am neither a complete beginner nor a canoeing expert.
One big frustrating I have about Canoeing on a river is sitting on a rock at shallow water. I am very bad at reading water. Can anyone suggest a resource (book, dvd, website) to improve my river reading skills. I am completely aware that actual practice on a river is essential to learn river reading but I am just looking something to facilitate my learning process.

Thanks in advance...
