Madison Fork Ranch (flotated Henry's Fork) June 25, 1979 Had arranged a float trip with Barry Schefflow of Bad Lilly's Fly Shop. He called for me here at 8:15 and we drove about 60 mi to the lower Henry's Fork & its Snake, above Ashton. Flotated all day, taking out at 6:00 PM at the main highway bridge where #20 crosses Henry's Fork. All river was continuous all day -- never a dull period. He caught somewhere around 30 & 40 rainbows apiece, many of them 10 to 15 inches. I shot a couple of bigger ones but didn't land them. I caught one brown trout of 10" or so which seemed to surprise Barry -- it appears there have been releases of browns in recent years but no sign of a real "take" as yet. Carl caught two whitefish -- that was all. A few of the rainbows showed strong traces of cutthroat lineage. Beautiful dry fly water -- lots of nice riffles and pockets along the edge of the stream. Very little slack water or unfishable shallows. Ospreys followed us along the stream all day and we saw one dive into a rather tumultuous rapid and emerge with a trout. Saw several female mergansers (which I take to be American) & one female with a very lively brood of third-grown young. Occasional hen mallards flew up or down the river. Added a dozen bird species to our list, including Eastern Cottontail, magpie, horned owl (flew across the canyon at noon), dipper, etc. Near Henry's Fork saw antelope and goat & a few cranes in flock of a dozen or so -- non-breeding yearlings?
