The definition of NON-bouyant lure restriction is on page 15 (definitions begin on page 14).

The reason for the definitions of course is have to expalin the rule just once rather than many times (the non-bouyant lure restriction must occur 50 times in just the West side rivers). If WDFW had to explain every definition every time it occurred in the pamphlet (single hook, fly fishing, catch and release, wild steelhead release, length, juvenile only, equiped with a motor, etc) the pamphlet would be much longer.
