DJ-
If this is the fish you are referring to, I do not how you can refer to that as a dark fish. Her belly is an umblemished creamy white and she is lightly suntanned. Plus, if you take a peak at the streamside foliage, you will heavily leafed trees that are just strarting to enter their fall colors.



And along those same lines, the lower rivers righht now (through early June) will recieve spawning steelhead that come in on the tide, spawn and leave...they are chromers and you would of never of known they were spawners except for a sunken and maybe a lightly darkened belly or pinkened fins etc.
