sanky Posted October 26, 2017 Share Posted October 26, 2017 I have fly fished for many, many years but I am baffled on the following question and I hope there is some clarification here. Why do fish not take BWO off the surface in the spring on the Bow like they do in the fall? Curious to see the answers... Quote Link to comment Share on other sites More sharing options...
scel Posted October 31, 2017 Share Posted October 31, 2017 I have experienced amazing topwater BWO fishing in late April and early May on the Bow, but it certainly does not happen every year. I think Bow River fish kind of forget to look up after a long winter Quote Link to comment Share on other sites More sharing options...

Always find the best dry fishing for baetis is following a big midge hatch as i feel like it retrains them to look up. Quote Link to comment Share on other sites More sharing options...
jksnijders Posted October 31, 2017 Share Posted October 31, 2017 Seen the same thing, big BWO hatches in the spring and nothing rising... and even the birds were in on it. Always seemed like it might be a temps issue/lack of having been on dries for the winter etc. Quote Link to comment Share on other sites More sharing options...
sanky Posted November 1, 2017 Author Share Posted November 1, 2017 Thanks for the replys! I also wonder if it has something to do with water level...low water= warmer water. Low water = easier to rise and eat dries than if there was deeper water? Quote Link to comment Share on other sites More sharing options...
Dangus Posted November 2, 2017 Share Posted November 2, 2017 I don’t necessarily like the depth idea, but a few of the above make sense. Could seem worse simply because for a chunk of the spring there are fewer fish around, And the remaining browns may be coming up more covertly/after dark. April 22, 2015, I happened upon 3-4 big browns going suicide on bwos. The one I hooked was 21” and there was definitely at least one that was quite a bit larger.

bcubed Posted November 2, 2017 Share Posted November 2, 2017 ya really depends on the year. forget which one it was, but there was a spring ~5 years ago that was absolutely nutty on midges, baetis and caddis all the way up to runoff. The following year they couldnt care less about the bugs on top except in pretty specific spots, even with the same number of bugs around..its super year dependent as there are tons of variables. 1 Quote Link to comment Share on other sites More sharing options...

I remember that year. Some of the shops were running out of parachute Adams before runoff hit, so everyone had their dry boxes stocked up for the next spring and there was no top action.

bcubed Posted November 2, 2017 Share Posted November 2, 2017 Ya, that was the year that virtually anyone could have caught a fish on top and they were easy to find as they were all eating dries like 12" cutthroat... i miss those years haha Quote Link to comment Share on other sites More sharing options...

Dangus Posted November 2, 2017 Share Posted November 2, 2017 That’s what that is, eh? Seems like a lot of expended energy for little gain. Thought it had to be bugs but Figured baitfish or eggs there. Quote Link to comment Share on other sites More sharing options...

Thought it had to be bugs but Figured baitfish or eggs there. Really obvious when you see them doing the bug-train. They fly to the top of a riffle, land, float down and eat bugs, then fly back to the top and ride the train again for hours. Quote Link to comment Share on other sites More sharing options...
Dangus Posted November 2, 2017 Share Posted November 2, 2017 Ya I’ve seen that, but what’s the dive bombing? They hover for a sec a 2-3 feet above and slam their heads into the water Quote Link to comment Share on other sites More sharing options...

sanky Posted November 2, 2017 Author Share Posted November 2, 2017 Thanks everyone for your insight! Last year a week before the May long week-end we were dry flying with cadis and having a hoot with both large rainbow and browns!

Sparkplug Posted November 3, 2017 Share Posted November 3, 2017 Perhaps the trout food options are different spring vs. fall. Certainly would be more chironomid larvae/pupae around in spring vs. fall, that could affect feeding patterns (subsurface vs. surface). Others (e.g., Brian Chan) have produced indicative trout food makeup charts for stillwaters, which show shifts in trout food priority/availability over the year.

They are a year-round staple in the Bow. When the BWOs come off in the spring, they are not as plentiful as fall, but they are also the only big hatch. The trout will surely key into the nymphs---an evil olive or WD-40 is are my key go-to flies. Until run-off, zebra midge is also a killer good fly. Really any size 18-22 nymph will work. The voodoo seems to be understanding when topwater becomes a valid food source. The larvae are definitely around. Like everyone else seems to believe, a calmer warmer March that allows a good blanketing of midges seems to be the warmup for a good dry fly spring.

Sparkplug Posted November 6, 2017 Share Posted November 6, 2017 Yes, while chironomids are in fact a non-biting family of midges, the question to my mind is whether trout in the spring in the Bow preferentially key upon chironomid larvae and pupae, as they generally seem to do in stillwaters. I don't fish the Bow nearly as much as I do trout lakes, but I see reports of plain red hooks working on the Bow early season that would strongly suggest chironomid larvae - bloodworms - in the trout diet. I would guess that in the fall, when there are fewer chironomid larvae/pupae available to the trout compared to spring (along with fewer larvae/pupae/nymphs generally), so less feed/biomass down near the bottom may have the trout looking up more.
