Big Cliff Reservoir, Oregon: Fishing Spots and Seasons

• Overview

  Big Cliff Reservoir is one of the Marion County listings for Oregon. Height above sea level is 1,230 feet. The water covers some 101 acres, so pick a bank rather than trying to cover it all. The outline measures near 3.6 miles, so local knowledge counts. Few waters listed in Marion County are bigger. Nearest town is Mill City, 10 miles off. Then Lyons, 17 miles, and Stayton, 26 miles. It sits well inside the county, so one set of rules covers it.

• Where to Fish on Big Cliff Reservoir

  Nothing we hold settles how deep this runs. Points where the flooded channel swings in are the reliable ones. Rip-rap along the wall holds fish that the open bank never does. Species logged across Marion County include bluegill, largemouth bass, largescale sucker and rainbow trout. The county list is broader than any single water. Fish Big Cliff Reservoir to its features, not to its size.

• Seasonal Patterns

  Typical August readings run about 61°F; by December the average is down near 35°F. Fishing continues through most of the calendar, with quiet spells rather than closures. It is not guaranteed from one year to the next. Autumn steadies things again once the heat lets go. Big Cliff Reservoir fishes to that pattern most years.

• Tackle & Baits

  We hold no note on access for this one. We find no slipway, car park or made path within a short radius, so treat access as rough. A small crankbait along the drop and a worm in the thick stuff cover the bass. State or provincial rules still apply whatever the bank status. Where tickets apply, they are sold in the nearest town rather than on the bank. Should this one be busy, Tumble Lake is 2.2 miles off. None of that is settled for Big Cliff Reservoir in what we hold.
