If this wasn’t a fly fishing blog, you might think this post was about our fellow Canadian rapper/musician who shares the same name. Come to think of it, the title of his hit song Started From The Bottom is surprisingly appropriate for the topic at hand. Maybe he was thinking about aquatic insect hatches when he wrote it… or, maybe not.
Of course, I’m referring to mayflies here, the Green Drake specifically. If you fly fish the upper Credit River, you probably know that the Green Drake has been going through a rough time. Once a prolific and highly anticipated mayfly hatch on the Credit, it underwent a rapid decline in the past couple decades and had all but disappeared. Dr. Henry Frania, an entomologist with the Royal Ontario Museum, has been studying the Green Drake issues for many years and rather than reiterate his findings, you’re better off Googling it yourself. Essentially, it had been found likely that the nymphs were dying due to ingestion of a toxic substance (chemical or organic). As a result, very few nymphs were reaching the adult stage, leading to the Green Drake being (for the most part) functionally extinct on most of the Credit River.
Fast forward to 2016 where (as I indicated in my previous post) the season started with some of the heaviest Hendrickson hatches seen in years. Blue Winged Olives were also in good numbers, followed by Sulphurs, Yellow Sallies and Gray Foxes. Next up was the infamous and ever-absent Green Drake. I was told they made a half decent showing in 2015 (relatively speaking), although I managed to miss them entirely. In serious need of a break from work and feeling optimistic with the number of bugs so far this year, I took a few days off in hopes of witnessing some of these giant mayflies. As it turned out, the weather and timing were perfect and I was able to spend three evenings among what was possibly the largest showing of Green Drakes since their decline many years ago.
