It has been said that the Musky is a fish of 10,000 casts. Although some folks are lucky enough to catch their first Musky in many less casts for most of us we have to put in the time, and the casts, to get that first fish. There are a number of reasons for this. One being that the fish themselves can be difficult to locate. Mostly, it is difficult to get them to take a fly. There is a certain amount of skill involved beyond simply throwing your fly in their face and stripping it back.
If you are interested in chasing Musky then you should read Dave Karczynski's article on MidCurrent, A Musky Fly Fishing Primer. Musky fly fishing is as different from trout as night is to day. Different rods, reels, lines, flies, leaders and techniques. Plus, you have to put in the hours to learn the fish. There is no way around it. Since there are now Musky in Eagle Creek Reservoir, a place to chase Musky is not an issue.
