The British Columbia 2005 Fishing regs are out . In this latest copy of the regs the following 2 definitions occur on page 8 .

1st definition

artificial fly ... a single pointed hook that is dressed only with fur, feathers, hair, textiles , tinsel and/or wire , and to which no external weight or external attracting device is attached . two or more hooks tied in tandem not permitted. Where gear is restricted to artificial flies, floats and sinkers may be attached to the line.

so far so good.

2nd definition

fly fishing ....angling with a line to which only and artificial fly is attached (floats and sinkers may not be attached to the line)

My conclusion...
So I guess if you have a sinker or swivel etc on your line or a Strike indicater you are by definition not fly fishing .If you are not flyfishing you cant fish in flyfishing only waters .

If you are flyfishing in flyfishing only waters by the first definition you can use a float and sinker , which by the second definition is not flyfishing so you cannot do it .
Another example of the government messing with my head .
