Fishing Rockhouse Reservoir in Malheur County, Oregon

• Overview

  Rockhouse Reservoir sits in Malheur County, out in Oregon. The bank is 3,796 feet above sea level. The water covers some 37 acres, so pick a bank rather than trying to cover it all. You are 70 miles from Marsing. The nearest city of size is Boise, 93 miles away. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Rockhouse Reservoir

  Depth went unrecorded, which puts the reading back on you. Look for where the old bank line still shows under the surface. A reservoir gives you a hard edge, a shelf, and not much else. Across Malheur County, recorded fish include rainbow trout, smallmouth bass, common carp and flathead catfish. The county figures include rivers and lakes alike. At Rockhouse Reservoir light and wind decide more than tackle does.

• Seasonal Patterns

  In an average year July sits at 70°F and January at 29°F. Conditions shift steadily rather than sharply. Some winters give nothing at all, so plan for open water. June to September is hot work, so the first and last hours are what count. On Rockhouse Reservoir the same rules apply, with local timing.

• Tackle & Baits

  Public sources are silent on who controls the bank. Nothing is listed nearby for parking or launching a boat. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Where a permit is needed, the nearest town usually sells it. Rules for boats are stricter than rules for the bank in many places. The nearest alternative is Anderson Reservoir, 13 miles out. Treat access at Rockhouse Reservoir as something to verify.
