Here are some pics of tiny "rills" I've perused that contained trout, from my print album:
These were headwater feeds to the upper reaches of trout streams in NY. My Dad and I loved to get in the car and drive until we found a crick that crossed the road. Out we’d jump and spend the day catching stuff. What fun. My Dad was a wonderful partner in the important stuff.
The tiniest X that contained trout were invariably spring seeps that didn't go dry or heat up. Nursery water they were mostly, but could hold decent fish in the right conditions, usually including high water. In most trout streams (surface water dominated), trout move a lot, and will follow flows up some pretty small feeds when conditions call. This is especially so of browns. In marginal waters they will move into headwaters where temps are efficient, where they hunt for small fishes and other stuff. More than one intrepid angler, who loves to explore and is willing to get his belly muddy, has been surprised by how little water good browns, or brookies, can live.
Lessee...a few stories:
Crazy Horse Fork
There was a stream that ran through my town that was not known as a trout stream. I spent many hours on that crick catching smallies, rock bass and chain pickeral in the mid reaches and chubs and other cyprinids further up. One summer, while fishing for pickeral and rock bass in the mid reaches, I had a huge spotted beast follow up my jig!
I hiked upstream and knocked on the door of an elderly woman who gave me permission to fish through. She also told me in the spring large trout would appear and chase minnows. I was armed with my glass fly-rod and some very crude home-ties and really little clue as to what to do with them. The creek there was 10 to maybe 20 feet wide, but with shale substrate it was very shallow. I didn't see any trout chasing minnows. But at one shallow cut where a sapling had fallen lying with the current,I spotted a white edged anal fin of a "large fish". I eventually poked it with my rod tip and out bolted a snaky brown of maybe 12 or 13 inches! With no place to go it wound up where it had started under the limb again. Wow!
I hoofed up to the next "deep" spot, a cut beneath a small tree all of knee deep, and teaming with chubs and minnows. I threw a rock against the roots and a big brown bolted out, spun around the little washtub sized pocket, and then back under the cut. My heart was in my throat! That brown looked to go 17inches! I moved another one of probably 15 or 16 inches from another tiny cut before hiking out.
Scud Brook
I rented a house that sat above a small warmwater stream that fed the mid reaches of a local trout stream. At that location though the main creek was a bit warm to hold many trout, which meant no one fished there. I found good numbers of carp and pike, which were great fun too. I was just getting hip to stream entomology and had found that little trib was FULL of scuds. I whipped up a weighted scud using gray squirrel hair, walked down to the trib to test it, and caught a 17inch brown on the first cast! I later caught others from 13 to 15inches. They remained in the little crick, feeding on scuds, until the flows diminished further and temps hit 70F. Then they disappeared. But the scuds proliferated.
You Found my SECRET SPOT!
I was exploring a local stream down into the warmer reaches, looking for spots that might hold bigger browns. In a copse of large mature willows I spotted line flash -an angler! "What is an angler doing here? Doesn't he know this is chub water?" (lol). He was on a hidden side channel that turned out to be a valley floor spring seep that was about 10feet wide and it turned out, 57F, whereas the main stem it fed on the other side of the copse was 67F.
As I watched from a respectful distance the angler (holding a spinning rod) turned and spotted me. "Oooohhhhh! You found my SECRET Spot!!", he blurted. He went on to spill his guts about being the only one to know and that he'd caught a 16" and a 23" brown there that summer. I assured him I'd not share his spot with anyone, and haven't. I'm no fool.
Lost Brookies:
I found a trib to a good brookie stream that ran through a lost “holler” in upstate NY. I had two of my apprentice FF kids with me, getting them used to knocking on doors. It was a little brook, about 8-12ft wide, running through woodlots, pastures and very rough looking homesteads complete with rusted tractors and cars dating back to the 40s. I was quite sure we were the only anglers to ask permission by the surprised and even confused looks on the homesteaders faces. One angry old woman wouldn’t let us on. But her neighbors above and below did. Wow! Were we glad we asked. We caught brookies up to 11inches, with 9s in every pool. They were uniquely colored with bright creamy yellow bellies that reminded me of indigenous char from the NE. On a later trip, one of my kids caught a 14” brookie (!), and later still had one wrap him up that he said was bigger! Holy SHT!
I've done some fisheries work too, and have shocked 17" to 20" browns from some pretty small feeds. These fish are not caught bc they are either inaccessible to most anglers and/or they eat big stuff. Who would fish a #4 streamer or bugger on .010 in a crick only a few feet wide? Sometimes it’s bc no one actually looks, or bothers to knock on a door.
