Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.

The plan
Plan A
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
Plan B
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Watch for
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Boat — drift
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

About this water
Lake Shumarinai is one of Japan's myth-fish waters — a remote northern lake, registered and managed for the Sakhalin taimen, where the fishing is deliberately rationed and the fish returned. Bear country and big-sky country, fished from boats by those who have planned for it, and the taimen here are a reason people cross the world and accept they may not touch one.
Under the surface
A remote, cold northern lake in the Horokanai hills, managed under registration and strict rules for its Sakhalin taimen, amemasu and trout along the shorelines. Spring and autumn are the windows; the rest is weather, distance and bear-country patience.
