Fly Fishing The South Fork of the Snake
River Idaho
The South Fork of the Snake River is one of Idaho's
better tailwaters. This is especially true if you like to fish
from a drift boat. That is by far the best way to fish the
river although it does have some excellent fishing for the
wader during the late summer and early fall season. The
South Fork of the Snake River flows from Wyoming into
the state of Idaho into Palisades Reservoir. The tailwater
flows from the Palisades Dam a distance of sixty-four
miles to its confluence with the Henry's Fork.

The South Fork has a population native Fine Spot and
Yellowstone cutthroat trout. It also has a population of
both brown and rainbow trout. In recent years the rainbow
trout population has caused some concern because it has
grown to the point is has affected the native cutthroat
population. The native cutthroat trout attain a very good
size with the cutthroats ranging from fourteen up to twenty
inches. The brown trout also grow large, commonly
exceeding twenty inches. The population of brown trout
increase in the lower section of the river

The water from Palisades Lake is used primarily for
irrigation. It varies greatly depending on the snow pack. In
the spring and summer, the flows are normally high. The
release of the water is strictly controlled by the amount
needed for irrigation. The water doesn't normally drop to
where wading anglers are not at a disadvantage until the
month of September. Autumn is the best time to wade the
South Fork. The river has a large variety of water types
consisting of long, deep pools, long sections of riffles, and
deep runs with islands and braids found along some of its
course. It has a tremendous number of aquatic insect
hatches that can provide excellent dry fly action thats not
common to many tailwaters.

Seasons:
Fly fishing the South Fork of the Snake River is good
throughout the season but the water levels will vary
considerably.

Spring time varies from year to year depending on the  
snowpack but is usually good for the most part.
