Pteronarcys californica

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

I caught a nice brookie a few weeks earlier in this pool at the junction of a split channel in the stream. The huge fallen tree is great cover.

Dorsal view of a Ephemerella mucronata (Ephemerellidae) Mayfly Nymph from the Yakima River in Washington

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.

I was curious if there is an under water camera that can be left in a pool that will transmit to the internet? If so how much would it cost. im tryin to find out what a small stream in my area holds. Even a camera that was trigered by motion or was on a timer would work. kinda like a game camera that hunters use.

d'you mean like those cameras they point at construction sites? we watched the new Nationals Stadium get built that way. too cool for words! a large construction firm might be able to steer you to whoever puts up cameras for them. then you'd need a waterproof box; oh, and some electricity...when it's up, be sure to let us know!

nothing that sophisticated. ive seen cameras in walmart that hunters set up on deer trails to see whats traveling by. There motion triggered. not sure if i could get a waterproof case for one. also not sure if just the motion of the water would set them off or not.

I would worry about the camera being either stolen or washed away.

It's going to be really hard to do what you want to do, and probably only possible if the stream is right next to your house. You need, at the very least, an electrical power supply, and probably a way to run computer cords out there. A car battery isn't enough power. You wouldn't want to try it unless you're really good with electronics.

I've looked into the possibilities for this pretty exhaustively in the last couple weeks because I'm going to do something similar with my research (though recording instead of transmitting to the Internet, which would be impossible unless tethered to a computer). For long-term surveillance I'm going to use an Aqua-Vu AV DVR ice fishing camera hooked up to two car batteries in parallel, and I'll still have to switch out the recording media every 8 hours to get 24 hours of video. Then I'll have to go recharge the two 50-pound batteries before I can do it again. Very far from ideal...

My recommendation is to figure out what's in the stream the old-fashioned way, by sitting on the bank and watching.
