An unscientific survey, hat tip to www.wisflyfishing.com, of successful flies on Mount Vernon Creek in the month of March. I read all of the stream reports on MVC in March over the last 10 years. Flies are listed in order of times mentioned in the stream reports. The list could make a good tying regimen as you prepare for opening day on Mount Vernon Creek.
