Learn to tie the Otter's latest patterns

Walt Mueller, Jr., aka "The Otter" (always in the water and usually catching fish), has been an avid fly tier and fisherman for over 50 years and resides along the Blue River in the Colorado Rockies. While also known for his many small nymph patterns, Walt has the distinction of developing and marketing the original "Soft Milking Egg"® fly patterns to the industry.

"The Otter" initially developed these realistic and deadly milking egg patterns for the Great Lakes steelhead areas that he fishes, they have also proven to be exceptional flies for all the cold water fish species worldwide -- from South Africa, Japan, Europe, Russia, New Zealand, Alaska, Canada, and the entire USA. His Otter's egg patterns are recognized worldwide, and are "Second to None."
