Middle Fork of the San Joaquin
The Middle Fork of the San Joaquin is a freestone stream that starts at Thousand Island Lakes (10,000' ele) , drains into Millerton Lake near Fresno, and eventually merges with the Sacramento River in the Sacramento-San Joaquin Delta. It is the longest river in California. The Middle Fork of the San Joaquin can be accessed by Road 203 which runs past the Mammoth Ski Resort in Mammoth, CA. This is also the only stream in California where one can hook into a Sierra Grand Slam (Brooks, Rainbows, Browns, and Goldens ) on one stream.
The Upper section is from Agnew Meadows to Upper Soda Springs Campground. This area holds hybridized Golden Trout which have migrated from the higher elevation lakes and mated with the resident Rainbows. The section has long riffles with pocket water and deep pools. This section is also within a dense forest with areas of swamps and high rock cliffs, so it takes some time to fish this section. Most of this water is good for dry flies, switching to nymphs for the deeper pools or early in the season when flows are up. There are two bridges that cross the river, one from below Agnew Meadows and the other at Upper Soda Springs Campground.
The Middle section is from Upper Soda Springs to Minaret Falls. The canyon widens in this section and consists of deep pools holding Brown trout in the 12-14" range. Fishing just above Upper Soda Springs will give you the best chance at a Grand Slam from one location. The Rainbows and Goldens will be in the faster water while the Browns and Brookies will be in the slower flows. Below Soda Springs Campground are additional campsites and this section tends to be heavily used within the summer months. A dry fly with nymph dropper is the preferred method through this section.
The Lower section is from Minaret Falls to Rainbow Falls. This section is a freestone stream holding mostly Browns. Most of this section is fast pocket water but there are a few large pools holding the larger trout. It's mostly a nymphing areas selecting spots behind rocks but becomes a very good dry fly section in the late summer, early fall.
Below Rainbow Falls is a small section of water containing small falls and pools with rainbows in the 10-12 inch class. This section goes to a second Fall which then drops into a steep canyon with vertical cliffs that is inacessable.
The San Joaquin contains numerous hatches. In June through early July, Midges will start and hatch all season. Golden Stones will show up and a PMD hatch comes off in the early evening hours. BWO's emerge in the Spring through July when the air temperature warms but tend to be more prolific in October. Caddis will show up in the late afternoon during much of the Summer. During late September and through October, the October Caddis appears as well as the Grannom Caddis. Trico's will show up near late October.
Red's Meadow provides a pack station, cabins, cafe, store, and showers to visitors of the area. It was started by Archie and Gladys Mahan in 1934 and named Red's Meadow after Red Sotcher who homesteaded the area. The road to the meadow was built in 1929 by miners eager for access to mining claims near Minaret Lake. The Tanner Family bought Red's Meadow from the Mahan's in 1960 and have owned and operated it since. The family also owns and operates the Agnew Park Station at nearby Agnew Meadows. Red's Meadow is a stone's throw from the PCT/JMT and is a popular resting area for through hikers.
A number of nearby lakes can be accessed from trailheads within the area. At Agnew Meadows Traihead (Elevation: 8300 feet) you can access:
Shadow Lake: Elevation is 8800 feet. The 51 acre lake is 2.9 miles from the Trailhead. It is mostly a level trail with a 750 foot
gain over the last mile to the lake. Contains Rainbows and Brookies.
Shadow Creek: Fish between Shadow Lake and Ediza Lake. There is about 2.5 miles of freestone stream between the two lakes. The stream
consists of pools and runs with some small waterfalls and a slow section through meadows. Contains Rainbows and Brookies in the 6-8 inch class.

Cabin Lake off-trail about .5 miles with a 500 foot gain. Finding the right outlet stream can be tricky. Just beyond the junction of Ediza
Lake trail and the JMT, the first stream crossing is actually from a glacier, take the second one. Ice-out for this lake is usually sometime in late July.
Contains Goldens that are periodically planted as fingerlings.
Ediza Lake: A 25 acre lake at an elevation is 9300 feet. About 5.5 miles from the Trailhead. Take the Ediza Lake trail from the
JMT which follows Shadow Creek to the lake. Ediza Lake is planted with about 7000 rainbow fingerlings each year. The holdovers reach
about 8-12 inches. The inlets and outlet are your best bet during the early evening hours. Contains Rainbows and Brookies.
Iceberg Lake: Elevation is 9800 feet. About 6.4 miles from the Trailhead. Contains Brookies.

mostly over the last two miles. Garnet is planted with about 18,000 fingerling rainbows annually. Many of these fish holdover and reach up
to 14 inches in size. There are a number of small islands amidst the lake. Try fishing the points and coves. Contains Rainbows and Brookies.

in the 9-10 inch class. Your best bet is early morning and late evening.
