Triangle Reservoir, Idaho: Fishing Spots and Seasons

• Overview

  Owyhee County in Idaho is where Triangle Reservoir sits. The setting is open valley on every side. With some 73 acres of water, there is room for a boat but no need of one. Roughly 1.3 miles of bank means you can walk to a fresh area when one goes quiet. Kuna lies 50 miles from the water. Mountain Home follows at 53 miles, then Nampa at 53 miles. The nearest boundary is a fair way off.

• Where to Fish on Triangle Reservoir

  Without a survey to go on, judge depth from how the bank falls away. The arms fish better than the open middle whenever the water is up. Levels move with the draw rather than the rain on water like this. Reported across Owyhee County: rainbow trout, great basin cutthroat trout and smallmouth bass. Records at this level tell you what is in the area. Work Triangle Reservoir in sections rather than trying to cover it.

• Seasonal Patterns

  Typical August readings run about 67°F; by January the average is down near 26°F. Whether it freezes depends on the year. It is not guaranteed from one year to the next. March through May is the strongest run, with October and November a second stretch. It holds true on Triangle Reservoir more years than not.

• Tackle & Baits

  Our records carry no access rule either way. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Parking is often the real limit rather than the bank itself. Some stretches are reserved and marked as such on the ground. Failing this one, try Johnson Reservoir, 11 miles away. Check the current arrangement for Triangle Reservoir.
