Welcome to OFF.
First, Eel Creek (and all streams) are closed right now. They won't open until May, for trout. However Eel Creek is now open for Steelhead.
According to "Oregon Coast Fishing Maps", by Pete Heley, sometimes Coho are caught in Eel Lake. But those must be safely released. Most of the larger trout are caught by fishing OFF of the bottom, in Eel Lake. You may also encounter SRC's, or an occasional Steelhead. So be sure to read the regulations, before heading out.
Also according to Heley's book Schuttpelz lake--and, more importanly, ODFW reg book--is strictly a Cuttie catch and release show. It's also an artificial lures and flies only pond.
Hall is primarily a Smallie lake. With an occasional native Cuttie--and a misplaced Coho (again the Ho's need to be safely released).
Hope that helps.
