Fourmile Lake is a lake in Klamath County, Oregon.
Without a dependable size figure for Fourmile Lake, weeds, rock, water color, and nearby depth are the best starting clues.
What Makes Fourmile Lake Different
Fourmile Lake sits east of Mount McLoughlin and sends water toward Fish Lake through the Klamath Project. Lake trout, rainbow, brook trout, and kokanee use cold open water and volcanic points.
Jig or troll near deep rock for lake trout, follow kokanee schools, and cast small spoons along cooler points for rainbows or brook trout.
How Fourmile Lake Fishes
Drawdown can reveal pumice shore and old creek shape. The man-made connection to Fish Lake does not make reports from the two waters interchangeable.
Fishing becomes easier when the trip starts with one goal: use volcanic points and cold open water for lake trout, kokanee, rainbows, and brook trout. On Fourmile Lake, that separates a real pattern from random casting.
A second pass should follow the same main idea, which is to use volcanic points and cold open water for lake trout, kokanee, rainbows, and brook trout, while holding the lure near the depth of the first two bites, changing speed once, and checking one nearby piece of matching water before leaving the area so the next move is based on a repeatable fish location instead of a guess or an old report from another part of the lake.
Fourmile can fall enough to expose pale pumice banks and move the useful edge far from the old high-water line. Follow the remaining creek shape toward deeper water. Lake trout still need a deeper pass, while brook trout may stay closer to cold inflow and smaller rock. Kokanee add an open-water search that should stay above their marked depth.
Fish and Baits
Fish listed for Fourmile Lake include Lake Trout, Rainbow Trout, Brook Trout, and Kokanee Salmon.
During a careful second pass near the edge of deeper water close to shade, cast a small spoon, inline spinner, light jig, or fly through cool water for rainbow trout.
How to Read the Water
During the last hour of daylight near a narrow cove with light wind, do not let the deepest number control the whole day; nearby cover, firm bottom, and food usually matter more than the deepest hole by itself.
Season by Season
During the first hour near a shaded bank close to shade, spring runoff can add color and pull fish toward fresh water; green weeds and the first drop become stronger summer targets; in fall, follow bait toward points and shallow flats, while winter rewards a slower search.
A Simple Tackle Plan
During a low-light period near the edge of deeper water after a cold night, a light spinning rod, thin line, a few small spoons, inline spinners, and jigs cover the listed trout; carry one slightly heavier setup when other fish or windy water call for more control.
During a check of nearby water near a shallow shelf after a cold night, record the wind, water color, depth of the first good pass, and cover after a bite; those four notes are more useful on the next trip than a long list of spots that did not produce.
During a low-light period near a protected point with stable weather, keep the first hour simple: use one moving bait to find active fish, slow down with a jig or natural bait on the best edge, and repeat the same setup when two bites come from matching depth and bottom during that part of the trip.
