    Marymere falls is on Barnes Creek. As I was fishing not far from 101 I saw and/or heard a number of day-hikers go by. Oh, and thanks! :)

    That's interesting and a little confusing because the name Salmo gairderni is the old genus and species name for rainbow trout. I would have expected the original name to be Salmo clarki crescentis.

    If Lake Cresecent has not been stocked with cutthroat and there are only two spawning populations (Lyre River and Barnes Creek), then there is only one type of cutthroat in the lake, the coastal cutthroat. The two "color types" of cutthroat trout being seen are probably due to different life history traits. The amount of rainbow introgression in the Barnes Creek population may play a factor to.

    Some interesting reading and notes on the Hatchery history and influences upon Cutthroat Trout in Lake Crescent and adjacent streams here:

    www.watrailblazers.org/science/crawford

    Also See there: "cutthroat trout, salmo clarki, Richardson . . . "In 1913 the Lake crescent hatchery was built . . .")

    Simply searching the term "Lake Crescent Hatchery" will glean reams of good references to this history and influence. Another sad example of our human impacts on a once wild fishery.

    Bruce,

    I just reread the section in Behnke's 1992 monograph I cited yesterday and think I see what caused the confusion. It appears that Jordan, upon not finding basibranchial teeth on the specimen in question, concluded erroneously it was a steelhead instead of a coastal cutthroat, thus the species name gairdneri.

    This nicely illustrates Behnke's point that 'splitters' like Jordan and his colleagues, were all too quick to conclude that differences between individuals were attributable to different subspecies instead of variations resulting from differing life histories. Aside from a complete lack of basibranchial teeth, every other aspect of the specimen that Jordan examined was consistent with coastal cutthroat. I guess it goes to show the problems with drawing conclusions of the basis of appearance alone.

    My apologies for needlessly complicating an already complicated situation. The fact that so many people still refer to the non-existant 'crescentis' shows how complicated things remain, even more than a century after the fact.

    I've included scans of the Behnke monograph relative to Crescent Lake and 'crescentis' below.
