Like most chums, Nisqually chums hit. Most likely you were casting too far. They travel really close to the bank in that colored water. Try casting no more than 10 to 20 feet from the shoreline. You can keep your leader as short as you like. A chartruse corky and chartruse yarn will get them, as will others, but chums do seem partial to shades of green. This from a guy who doesn't even fish for chums.
