Pteronarcys californica

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

This is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).
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.

If you can get access to old issues of FlyFisherman Magazine, here are some references from my indexes. I'm sure there are some guidebooks to Colorado, and perhaps to the South Platte. Check Amazon. Some libraries can get things on interlibrary loan, including photocopies of old magazine articles. Try an academic library if your local one can't.

FF just means FlyFisherman, then the month and year of the issues. Hope this helps.

Google "fishing shops Denver" and check with them. There are alot of choices and they all should know about Waterton. My personal experience is limited since they built Strontia Springs dam. Before the dam there was a good Pteronarcys emergence about now and lots of mayflies. Now there is often little water in the stream and it can be just midge fishing. Check - http://www.dwr.state.co.us/surfacewater/watertalk.aspx or the shops for flows. I suspect there is other access to the gages. Waterton is a narrow canyon and as the flows go up the access gets tougher. Stand on a rock and cast. The catch and release section is at the top of the canyon so expect a walk (or a bike - no cars) but it is pretty flat and a nice road. I think 3 miles to the start of C&R and then another 3 to Strontia Springs dam. And bighorn sheep often on/near the road - and snakes (a native) and poison ivy (real rare before the dam). Another area that may be OK depending on the flows is the area downstream from the Kassler Bridge. Just wander downstream from the Kassler/Waterton Parking area instead of up. No sheep, never seen a snake but alot of poison ivy. Fish can move up from Chatfield Reservoir and I have seen some nice browm and holdover bows.

Have fun!

Here's some info on the South Platte. Google "San Juan" for more Troutnut info on it.
