dark snaggled tooth..clogging up fishery... means when you are drifting your corkies for steel head through the normal steelhead drift lanes but, there are BLACK DEFORMED SPRINGERS in the lanes rather than steelhead, so they either bite them or get caught on them, forcing you to deal with them for 10 or 15 minutes or so trying to save your steelhead gear & line, so the bulk (almost all) of your time is wasted on the springers,

as to the snaggers, you see them up there from time to time & from time to time you see the game wardens write them up & then those people don't come back & a few days later new people come & snag until they get wrote up ... and so on ...
