there is a little challenging
because Devilís Postpile National Monument is located along its banks and
draws lots of tourists, so many in fact that the U.S. Forest Service has had
to limit the numbers of vehicles that are allowed in the area each day.
Vehicles are only allowed to enter the area before 7AM and after 5PM.
To reach it from Mammoth Lakes, travel west on
There are lots of planters around the
campgrounds but to catch the Rainbows, Browns, Brooks and Goldens to
achieve the Sierra grand slam.
You will have to get away from where most of the people are.
One good section to try is higher up near the Agnew Meadows pack
station where you will have to go on foot for awhile to reach the river.
Though you will come across a fair number of humans, almost all
of them are backpackers who are on their way somewhere and donít have
time to stop and fish, consequently fishing pressure is lower and the
fishing is better. This is
the section where I got my first Sierra grand slam.
Gear and tackle is very straightforward and a four weight rod will suffice most of the summer. In the fall, a two or three weight will be fun to fish in the thin water. Use a floating line with 5X tippet and basic attractor flies like Royal Wulffís, Ants, Adams Parachutes, and Elk Hair Caddis are all that are needed. For nymphs, small Pheasant Tails, Birdís Nests, Copper Johnís and Princes work well.
