Fishing Tualatin Reservoir in Washington County, Oregon

• Overview

  Within Washington County, Oregon, you have Tualatin Reservoir. It sits at 197 feet above sea level. Surface area runs to about 2 acres — small enough to read in one session. Tualatin lies 1.6 miles from the water. Portland sits 12 miles out, and it is the nearest city worth the name. The county edge is within a short distance of the bank.

• Where to Fish on Tualatin Reservoir

  There is no published depth for this one, so start shallow and work out. Look for where the old bank line still shows under the surface. The old creek line under the surface is the feature worth finding. Records held for Washington County cover common carp, yellow perch, brown bullhead and largemouth bass. Records at county level tell you what is around, not what is stocked here. At Tualatin Reservoir the water rewards a slow, careful approach.

• Seasonal Patterns

  July is the warm end of the year here, averaging about 67°F, while December sits near 40°F. The surface stays open the year round. Heat pushes fish deep from June onwards, so start early. April and May are the settled weeks, with October close behind. Plan any trip to Tualatin Reservoir around it.

• Tackle & Baits

  Public data does not answer the access question here. A carry of half a mile from the nearest parking is the price of fishing here. Part of this sits inside or beside Hedges Creek Greenway, so read the notices. 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. The nearest alternative is Schaber Reservoir, 3.9 miles out. None of that is settled for Tualatin Reservoir in what we hold.
