Lone Tree Reservoir Fishing in Malheur County, Oregon

• Overview

  Lone Tree Reservoir belongs to Malheur County, Oregon. The bank gives way to open dry country. Around 26 acres of surface means several distinct areas to work. Nearest place of any size is Marsing, 72 miles away. Boise sits 89 miles out, and it is the nearest city worth the name. No county line comes close, which keeps the paperwork simple.

• Where to Fish on Lone Tree Reservoir

  This water is saline; the fishing interest, where it exists, sits in the feeder streams rather than the basin itself. The basin is ephemeral: it can stand empty for years between fills. If you are set on fishing this area, look to the rivers and fresh waters nearby instead. The arms fish better than the open middle whenever the water is up. Standing timber shows when the level drops, and fish sit against it. Treat Lone Tree Reservoir as a water to read rather than to cover.

• Seasonal Patterns

  On the long-term average, August reads 69°F and January reads 29°F. Seasons here are moderate, and the fishing runs most of the year. In milder years the edges alone go, and the middle never sets. November and March are the quiet, comfortable months to be out. Expect Lone Tree Reservoir to follow that timing.

• Tackle & Baits

  Public sources are silent on who controls the bank. Mapped as intermittent, it fills after rain and shrinks between. There is no recorded infrastructure here; expect to find your own way in. Check locally before you travel, because a wasted drive is a long one. Keep proof of licence with you rather than in the car. Three Forks Rim Reservoir at 2.7 miles is the sensible second choice. Treat Lone Tree Reservoir as unsettled until someone local tells you otherwise.
