• Where to Fish on Sewell Reservoir

  Nothing in our records gives a depth for this one. Draw-down through summer strips the margins, so follow the water out. Points where the flooded channel swings in are the reliable ones. Owyhee County records list rainbow trout, great basin cutthroat trout, smallmouth bass and channel catfish among the fish reported. Take it as the county picture rather than a promise for this water. The shape of Sewell Reservoir decides where the fish sit.

• Seasonal Patterns

  The seasonal spread runs 25°F to 66°F. A long season, with weather mattering more than the month. In a normal year the cover is thin and short-lived. April and May are the settled weeks, with October close behind. That is the shape of the year on Sewell Reservoir. Short days concentrate it into a narrow window.

• Tackle & Baits

  Access is not recorded for this water. Nothing built is recorded close to the bank here. A small crankbait along the drop and a worm in the thick stuff cover the bass. Rules for this water may differ from the county norm. Barbless rules turn up on managed water more often than not. Little Blue Creek Reservoir at 3.2 miles is the sensible second choice. Treat access at Sewell Reservoir as something to verify.
