Hebgen is a big Madison-river reservoir, and in summer it's famous for its 'gulper' fishing — pods of heavy wild rainbows and browns cruising the calm flats on a still morning, sipping Callibaetis and Trico with a little audible gulp that'll fray your nerves in the best way.

Species

A patient day, if you fancy it

Glassy and bright — hard work without a breeze. A flat lough is a quiet lough — wait for the breeze.

How to fish it · for brown trout
When
No strong hatch signals at the moment — general searching tactics should work best. Calm conditions may limit drift fishing — consider buzzers or dry fly if fish are rising.
Where
With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the calm, a single dry fly or a slowly-fished nymph tends to out-fish an active retrieve.
The plan
Plan A

With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the calm, a single dry fly or a slowly-fished nymph tends to out-fish an active retrieve.

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.

Bank

Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.
