Fishing at Opal Lake, Marion County, Oregon

• Overview

  In Oregon, Opal Lake falls inside Marion County. The ground around here is rolling hill. This is a pocket water of some 13 acres, and every part of it is reachable from the bank. The closest town, Mill City, is 13 miles away. Salem is the closest city, 41 miles away. No boundary runs near, so the county rules hold throughout. Conditions change the water more than the calendar does.

• Where to Fish on Opal Lake

  We hold no survey for this water; read the slope of the shoreline instead. A natural lake fishes on cover, and cover here means weed and timber. Still water like this holds fish on the edges rather than out in the open. Reported across Marion County: bluegill, largemouth bass, largescale sucker and rainbow trout. What holds for the county may not hold for this water. Fish Opal Lake where the bottom changes rather than where it looks deep.

• Seasonal Patterns

  August is the warm end of the year here, averaging about 59°F, while December sits near 33°F. Mild ends to the year keep the season long. 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. Plan any trip to Opal Lake around it.

• Tackle & Baits

  Our records carry no access rule either way. You will be walking about half a mile from the nearest car park. A small crankbait along the drop and a worm in the thick stuff cover the bass. Parking is often the real limit rather than the bank itself. Some ground is open by custom rather than by right, so tread carefully. The nearest alternative is Tumble Lake, 3.2 miles out. Nothing on Opal Lake should be assumed from this page alone.
