The dark Bass are the more natural strain U find them in natural Lakes like Wampus, Mohansic .Most fish in the Reservoir are stocked and seem lighter in color . I think there are a few more Strains if you look at Smallies some are very dark they may be from the Creeks that got flooded when they made the Reservior, some Green ones, and typical Bronzie Great lake strain.I guess there are some native Brookies around .Hopefully those Brookies get thrown back !
