The diagram above shows a bird’s eye view of river with a fisher in different casting situations, which are determined by the wind direction and the closest river bank. By convention right and left apply when looking downstream. The diagram illustrates how the fisher must be adept at casting from both the left-hand and right-hand sides of the body in order to be able to cast efficiently under all conditions and to make sure that the fly is always downwind, so that it cannot cause injury.
The single Spey cast applies for all wind directions except a downstream wind. For an upstream wind there are two other casting methods that can be employed; the circle cast and the snap T. For a downstream wind the double Spey or the snake roll can be used.
The following is an explanation of some of the terms used in the casting section of this website.. Not all of these terms are in general usage but have been introduced to make it easier for the concepts to be explained.

The following symbols are used throughout the Spey-casting casting explanation diagrams

I do hope that you will find that the diagrams are helpful. However, nothing is quite as good or quick as using a qualified casting instructor.
