The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This is an interesting one. Following the keys in Merritt R.W., Cummins, K.W., and Berg, M.B. (2019) and Jacobus et al. (2014), it keys clearly to Ephemerella. Jacobus et al provide a key to species, but some of the characteristics are tricky to interpret without illustrations. If I didn't make any mistakes, this one keys to Ephemerella mucronata, which has not previously been reported any closer to here than Montana and Alberta. The main character seems to fit well: "Abdominal terga with prominent, paired, subparallel, spiculate ridges." Several illustrations or descriptions of this holarctic species from the US and Europe seem to match, including the body length, tarsal claws and denticles, labial palp, and gill shapes. These sources include including Richard Allen's original description of this species in North America under the now-defunct name E. moffatae in Allen RK (1977) and the figures in this description of the species in Italy.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Eight fish hooked, all but one 14-20 inches, five landed up to about 17 or 18 inches. The biggest fish, 20 or more inches, broke the last Orvis knot I'll ever tie, but more on that in the knots thread. I did get a very good look at this fish, which had not made any strong runs when the knot failed. This was a good trip for me, though with a little less rain the last day might have been better. Still, I'm always thankful to get a nice sized brown on the upper West Branch to eat a dry fly, and that happened twice for me. Both of those fish were landed.

Hi Louis,

Sounds like conditions were pretty challenging, but I guess that is to be expected on the WB at those water levels. You must have been dragging your canoe in a few spots. Glad to hear that you got a few of those fickle fish to take. Tough luck about the knot on the big fish, but better to have loved and lost....

Jeff advised me not to even think about putting my boat in, so I was wading the Deposit area and the Gamelands. Those Ph.D fish piled it higher and deeper often. It was only thanks to tricks you guys have taught me that this blind pig found an acorn or two here and there. My best defense was a nymph dropped off a dry, and the last fish I caught, a very energetic 16 incher in the Gamelands took a sulphur wet fly dropped off a glow spinner. He made several long runs in the dark and had me wondering just what I'd find if I ever netted him. The big fish that broke the Orvis knot (which wasn't under all that much stress when it snapped, by the way) took my last brown polycase nymph. Back to the vise.

Yeah, I was wondering about that. I've found that the water needs to be about twice that level for a decent float. Sorry you didn't get to use your canoe; I know how much you love that. It doesn't look like the Water Masters are being very generous to fishermen or to trout this summer.

Louis,
Any sign of Iso's? I know we are out of the prime time but you never know.......

How was the temp on the mainstem running? I've developed a fondness for the "Big D" over the "Branches" the last two summers.

JW, I didn't see any, but one clearly knowledgeable angler I talked with recommended running an Iso down a seam if nothing else was going on. He said they were still hatching sporadically throughout the day. I didn't talk with anyone who was fishing the big D, and Jeff at the Delaware River Club would have recommended it if it was fishing well. He too prefers the big D, and I always try to fish it some when I can. I didn't check the temp for the upper river, but it was hitting near 70 downstream at Lordville or Callicoon. From what I heard, there were few bugs at Junction Pool, and only evenings. Even the Gamelands was relatively quiet and only saw some action at dusk. Deposit and Stilesville were the places to fish, and there were plenty of sulphurs there from 1-5, and later, especially in Deposit on Wednesday in the rain. Too bad almost no fish were rising.

Louis,
I get a litle turned around up there. Is Stilesville above or below Deposit? I remember fishing a section off of 17 where there was a small pull off just upstream of a small pasture between the road and the river. Not quite sure if it has a specific name or not.

Most of my experiences up there are from the vicinity of the 191 bridge (by the Wild Rainbow shop) down and then the mainstem down to Stockport. Believe it or not I have NEVER fished the Gamelands. I may need to remedy that this summer/fall.
John

JW, Stilesville (I hope I'm spelling it right; I only had oral directions to it) is upstream from Deposit. This was my first time fishing there, and the first time I waded the Gamelands. I typically float in my canoe to try to find some less educated fish (a hopeless pursuit anywhere on the Delaware it seems). I've floated the East and West Branches, and the main stem down to Callicoon--not at one time, of course :). This was my first wading trip in years, and although the conditions were tough with the low clear water, I liked the ease of getting around and the way fish were stacked up. It was easier to find fish, though perhaps harder to get one on. I always approach the Delaware with both excitement and dread (due to several sound skunkings there), but I'm learning to get over the dread. I think.

hey, 8 fish is not bad on the D, especially with the low conditions. I'd say you did well. If you were working fish the entire time, thats all you can hope for. The gamelands is very good.

I might be up there in mid/late august if they are generous enough to allow enough water to float it.

Unlike most guys, I go there to streamer fish and night fish. But have landed a 25 incher one year on a spinner. that was pretty memorable. its the rod stopping streamer takes that get me going back.

Night fishing can get good- when the giant stones are happening, or tight lining a mouse down and across.

fun fun fun!

Dave
