The Manhattan Midge is a pattern I developed to fool finicky Rocky Mountain trout, especially those found in tailwater fisheries. As you might imagine, there’s an interesting story behind the Manhattan Midge. The Manhattan Midge, as the name implies, was developed in a small New York City apartment where my close friend, Jay Park was living at the time.
Jay and I met in New York City during the winter of 2014 when I was working at the Orvis Store. We immediately became friends because we shared a similar passion for fly fishing and tying flies. When you live in the concrete jungle, you have to live your fly fishing dreams vicariously through DVD’s, magazines, YouTube Videos, and tying flies. Tying flies was more than a hobby for Jay and I—it was an addiction!
Tying flies kept us connected to the sport. Once a week, Jay and I would rendezvous at his apartment to tie flies. Each week we tied different flies but usually focused on tying Colorado staples. We tied a lot of bugs that winter; I mean a lot! We both tied up two boxes of “bugs”, which was an addition to a huge inventory of flies we had already amassed in recent years.
For quite some time, I wanted to develop a midge pattern for western tailwaters. My goals and objectives were simple—create a midge imitation that was easy to tie, durable, and most importantly consistently fools selective Rocky Mountain trout. After having success with some of my father’s flies; I knew I wanted to incorporate three materials into the design—Glamour Madeira, peacock herl, and a small silver-lined glass (mercury) bead.
The Manhattan Midge is a souped-up hybrid of some of the Dorsey family favorites—the Top Secret Midge, Mercury Black Beauty, and Mercury Blood Midge. The Manhattan Midge incorporates the best attributes of each of the previously mentioned patterns. It has a slim profile, a fine-segmented body, a flashy wing, peacock collar, and a clear, silver-lined bead to imitate trapped air bubbles in the thorax prior to emergence.
Over the past three years, the Manhattan Midge has become a local favorite on the South Platte River (Cheesman, Deckers, Eleven Mile Canyon and the Charlie Meyers State Wildlife Area) and its effectiveness has spread to eastern tailwaters as well! Several guides in Colorado consider it to be one of their top guide flies. “I have been a fly-fishing guide on the Gunnison River for over 25 years. The Manhattan Midge is one of our top producing patterns when midges are emerging. It is the perfect attractor…I run the Manhattan Midge as my lead fly and a Flashback Mercury Black Beauty as a trailer. I am sure some mornings that combo hooks every feeding fish in the run” says Jason Booth, co-owner of Gunnison River Guides.
Tying and Fishing the Manhattan Midge
I fish with the original Manhattan Midge (black) a large percentage of the time. I also carry it in a handful of other colors including; brown, olive, red and purple as well as a flashback variation. The flashback version incorporates a piece of Mylar tinsel as a back strap across the abdomen, overlaid by a copper rib. Each variation has its time and place, so don’t be afraid to think outside the box from time to time and mix things up.
Midge feeders eat the Manhattan Midge year-round with confidence. The size and color of the pattern varies slightly depending on the time of year. For instance, during the dead of winter, I typically use a size 22, but during the spring months, especially in March when the big spring midge hatches, I often use a size 18. During the summer months, I find myself fishing with a size 20 most of the time. Visual observation of the adults flying above the water helps you decipher which size to use.
The Mahattan Midge can be fished as an attractor or dropped off an egg pattern, San Juan Worm, or red midge larva. In riffled water, I recommend using the Manhattan Midge as a dropper, but in slow pools and tailouts, where trout often scrutinize your flies, I like using the Manhattan Midge as an attractor and trailing (one or two) midge pupa or mayfly emergers behind it.
