Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

Nymphs of this species were fairly common in late-winter kick net samples from the upper Yakima River. Although I could not find a key to species of Zapada nymphs, a revision of the Nemouridae family by Baumann (1975) includes the following helpful sentence: "2 cervical gills on each side of midline, 1 arising inside and 1 outside of lateral cervical sclerites, usually single and elongate, sometimes constricted but with 3 or 4 branches arising beyond gill base in Zapada cinctipes." This specimen clearly has the branches and is within the range of that species.
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.

Here is a picture of a truly wild, gorgeously colored, brookie caught at the flume at the top of the "Ditch" on Big Spring back in the early 1990's. I watched another guy, catch, and kill this fish. It was about 14" long.

That's a great fish. Do you live in the area or were you there visiting. Do you have any recent photos?

I live in York, PA. Big Spring is in Newville, PA about an hour and a half drive NW from my home. At one time there was a large PA fish hatchery situated at the uppermost end of Spring Crrek. Others here can correct me if I wrong but the hatchery was actually slightly above the springs that form Big Spring. The hatchery dug wells for the trout races and the water flowed out of the hatchery and into the stream. This outflow far exceeded the normal cfs rate of Big Spring and for many years the water literally gushed out of some sluice gates immediately below the hatchery.

I liked the flow then and while the "heyday" of wild brook trout thoroughout the creek was long gone there were still a surpising amount of wild brookies in the 10" - 15" range in the swift water and throughout the entire length of what is called "The Ditch".

Effluent from the trout hatchery degraded the natural ecosytem of the creek and the immediate land adjacent so after much verbal wrangling the state of PA closed the hatchery. I don't know the date of the closure but it was about four years ago.

I never liked the fishing in "The Ditch" when the hatchery was present and now after the closure the natural outflow of the underground springs are so minimal that there is very much less water flowing in the creek. I would never recommend Big Spring as a "destination trip" for anyone who lives more than half a day's drive away. In my opinion the fishing is boring, there is only about 150 yards of water that has any depth to it, and most of the fishing is done with midge nymphs and those stupid indicators.

Some proponents will likely say that there has been an improvement in the fish holding capability below the iron bridge but I've yet to see any fish in the crystal clear water rising or even just finning in the current.

No, I have no recent photos of this area.
