This year the fishing started our pretty good. One their smaller lakes yielded two rainbows and 7 brookies in about two hours, some of them a good size like the top pic here.
The same evening I caught the above Char about 19" and heavy. I spent so much time trying to get a good picture, I didn't want to keep it longer for a weighing. He obviously wasn't all that upset because he took my point fly before I could get it out of the water. Best combo was a Vampire Leech as dropper and a PT Nymph at the point. This lake has a significant' mayfly hatch. Can't identify the mayfly but it is small and dark.
Then the weather changed on us in severe way. On Saturday it was 32C in town then dropped to 9C, cold, wet and windy. The fish turned off the next day and many in our group were skunked. The char lake stayed off. I managed to get nine small brookies on my way out at the much smaller Verra
The fish were very tentative and those in faster moving boats were not going to get many, if any. In the float tube you were able to feel the gentle touch, then stop completely and slow retrieve. Sometimes they wouldn't take it until you had most of your line in.
I used my 3 wt dry line with added sink tip most of the time. great way to fish. The sink tip finds its stable position and stays there. Great if you can determine the right depth. I was fishing mainly 8 to 15 FOW.
I got reports that a local lake which had no sign of trout all Spring has all of a sudden got fish all over the surface. They will follow the hatch.
