It still has Brookies. The article sensationalizes it a little bit. But yes, there are still Brook Trout in Segloch. My guess is if you shocked it, it’d be about 50/50 numbers wise, but since we use biomass as the measuring stick, I think it is fair to call Segloch a “Brown Trout” fishery at this point. And probably also fair to call it a mediocre one, at best. But catch it over the warmer months when it’s up a bit, and toss a dry fly only, and you’ll catch some dinky Brookies along with the (relatively) larger Browns. If you put a nymph on, even off the dry, you’re just gonna catch Browns in those conditions.
The bigger issue, as has been much discussed on here, is the red sandstone geology making it difficult for the stream to make and keep good habitat as everything fills in with sand.
Been a few years since I’ve fished it. Not gonna burn a primo conditions day on it, but maybe I’ll give it a cabin fever outing this Winter. See if high water temporarily moved the sand around.
