Late Fall/Early Winter
Droughtish weather is here too –about 2 months now. Except that flows aren’t esp bad bc winter-killed vegetation is not siphoning water, and two things mostly unique to the west -water isn’t being siphoned off for agricultural use as it is spring and summer, and also there is some snowmelt contributing from the high country. But, since we’re here to talk fishing, I’ll pony up some on my experiences/thoughts on fishing in low flow.
Species:
Trout species react differently. Both brookies and browns will feed in very shallow depth, esp if there is some overhead cover –this last is esp so for browns. With adequate temperature, these fish will accept low food rewards and stay on station. Lotsa anglers spook these fish. My fishing report “Stealth, Patience, and NO micro-drag” describes such a situation. On that same day, those sports and their guide could have caught some fish on their chosen nymph rigs, had they targeted the turbulent head riffs where they could have gotten away with their clunky presentations.
A sanctuary needs to be nearby too, for browns and brookies, and the adequacy of these change with flow. Trout in streams that have variable flows tend to move a lot, as habitat (sanctuary, food availability) changes.
‘Bows tend to be more current oriented so they are less apt to look for food in the slack shallows, and much more apt to hole up in larger pools or runs and may really consolidate there. (This is true of stocked browns too). In waters with few sanctuary crevices, or undercuts left deep enough, wild brown and brooks will consolidate on pool bottoms, using depth rather than cover for sanctuary. This is more likely as temperatures drop as winter settles in too. Regardless of species, these consolidated pool fish can be micro-nymphed, with patience; Viscous water and/or trout lethargy requires precise drifts and detection. Likely sanctuary cover can be long or short-line nymphed, or “flipped” –short-range weighted and snag-guarded wooly buggering. For long range nymphing I like buggers, big leggy nymphs or wets, and I have a crayfish pattern I like a lot too. Size depends on water volume and fish size. Streamers and big wets can work by hanging and hand twisting in a sanctuary.
Temperature:
Temperature is important to trout’s overall activity; their willingness to feed or move at all. I’ve witnessed during severe droughts with high stream temps, trout (browns) holed up under rock crevices and just waiting it out –occasionally and inconsistently coming out for very short periods. I’ve also found them ram-jetting in riffles (this came up in an earlier post I think). In general though, it takes extreme conditions to put them off for long. Feeding is what fish do for a living. If temps are in a good range, then trout are usually at least willing to feed. If the stream is not super-rich in productivity like a tailwater, then you can expect some trout to be active all day (super-rich trout can get spoiled). The tricky part, IME (in my experience), is when nearing the upper temps, the 60s. It seems that fewer trout are goaded onto station on most streams (not super rich). It’s been said that 61 to 64F is “optimum”…well… “optimum” doesn’t stand alone, it’s in relation to available food to match it, so again IME, it’s the upper 50s that are “optimum”, when trout are willing to weather poor rations and still stay on station.
If temps are not breaking 45, then you may be looking at winter quarters already. That can vary with stream and individual fish but think slack water until the sun warms things. Early on, like now, it seems lotsa trout like to stay around summer turf as long as possible –kinda like we’re doing lol. Likely some of these are new fish moving around and just passing through too. The spawn is on too, moving lots of fish, or wrapping up and recuperating fish tend to be hungry. I use egg patterns a lot this time of year. Some of my earlier formative years (I’m still in em) were spent on Great Lakes tribs so egg patterns are a true “hatch matcher”. Brown eggs are yellow-ish to pale orange-ish, brookies orange-ish, and ‘bows pink-orange-ish, suckers pale yellow-ish or yellow-greenish.
Altered Feeding Behavior:
If there is little in the drift some fish may switch feeding strategies. If in pools they may begin to cruise like they would in a lake or pond. Unless there are a lot of say, cased caddis keeping them focused on the bottom, they may cruise keeping track of the entire water column top to bottom; gleaning a cased caddis here, intercepting a midge pupa, sipping an ant from the surface. This has always been tough fishing in my book because, first, trout (fish in general) are pretty near-sighted –or their attention is so–and they may not see our fly (looking appropriate) unless things are lined up just right. And since this type of behavior most often happens during low flow when water is usually clear and flat, it’s VERY easy to spook them. The one saving grace is that trout will often run a habitual circuit around the pool or section of it. You can observe the pattern, cast ahead and then twitch the fly as the fish approaches. This is sight fishing under low flow, and some pools are arranged better for this approach than others. Patience is as important as stealth here. Some people simply don’t want to work so hard for single fish. Teaches you a lot about just how ridiculous flies can look in still water, and will get you back on the vise rethinking things.
Prime Options:
-Crack of dawn behavioral drift is THE prime time –esp if you’ve got Baetis that should be emerging now. Interestingly, I’ve seen nearly entire autumns go by with precious few “good” Baetis emergence days. I’ve wondered, but never checked, to see if they emerge after dark, or just before light –like summer mayflies will.
-Midges are the most common winter fodder. Micro-nymphing midge pupae anytime of day is a virtual no-brainer bet.
-Egg flies simply work. And if they make your skin crawl, pump or kill and see for yourself –trout eat eggs that are abundant from fall, all winter, through spring (if bows or suckers are present).
-Hatch matching isn’t the only game in town. Cover/sanctuary probing using big buggy nymphs or big buggy … buggers. Hanging, or slow hand-twisting wets or streamers upcurrent works too.
Input:
-Trout species
-Where are they?
-What foraging behaviors are they using?
-What presentations fit those water types and behaviors?
-Apply stealth, especially patience, and adjust your expectations. You are probably going to have to earn your fish.
OK –enough –I’ve actually got clouds so I’m going to see if I can get an hour or so in on a nearby stream myself. …
Well…didn’t get this out until now, and I’m back from fishing. Clouds melted and sun reappeared. Water was very clear and cold: 37F (11am) and 39F (4pm). It’s winter here, despite the sunny days and 2 months of droughtish weather. Hit two streams, a tiny brookie near-headwater for an hour and sight-fished and blind-fished a weightless midge larva or #20 Baetid nymph to brookies in very shallow holds. They held on station like it was summer, but would not rise up through that foot of water to take a dry Baetis –and I tried. Still wonder if they might have taken a dry midge (kinda doubt it though as they needed to have the larva and nymph at near eye level). One was 9inches. Then on to a larger stream for browns, using only a #14 yellow egg fly.
