A grey, even sky over the water, with dead-still conditions with the glass slipping lower. Fish at Bump Reservoir should hold close to the arms and the first breakline. The strongest window runs from the day. Stay mobile and follow the activity. Shortening days concentrate the feeding into fewer hours.

Set in Washington County, Bump Reservoir is an Oregon water. Elevation runs to 1,014 feet. At roughly 8 acres, the whole thing is within casting reach of a single walk. Banks sits 6.6 miles from the bank. Hillsboro is the closest city, 14 miles away. The nearest boundary is well away, so one set of rules covers the water. The near end sees the visitors; the far end rarely does.
Open data we checked carries no depth for this water. Points where the flooded channel swings in are the reliable ones. Built water gives depth close in, which suits a bank angler. Records held for Washington County cover common carp, yellow perch, brown bullhead, largemouth bass and black crappie. The county figures include rivers and lakes alike. Bump Reservoir gives up its fish to patience rather than distance.
Between December at about 38°F and August at about 62°F, the water has a wide range to work through. Conditions shift steadily rather than sharply. In milder years the edges alone go, and the middle never sets. The cooler months are the comfortable ones to fish here. The season on Bump Reservoir follows the weather closely.
Whether the bank is open is not something our records settle. No made access is recorded, so a short walk in is the likely arrangement. A small crankbait along the drop and a worm in the thick stuff cover the bass. Where a permit is needed, the nearest town usually sells it. Where tickets apply, they are sold in the nearest town rather than on the bank. Spaniol Reservoir at 0.7 miles is the sensible second choice. Check the position at Bump Reservoir before loading the car.
