Mike -
You seem to be discribing a large scale sucker -aka "golden bone" or "Skagit bone fish".

They are a common fish in our NW rivers and some of our more advance fly anglers have spend considerable time perfecting their presentation methods so that they can encounter these extraordinary fish. The nicknames above are the result of further attempts elevate the accomplishment of "hooking" one of these fine fish.

Remember one's "garabage" may be another's "trophy".
