Henry Hagg Lake & Scoggins Valley Park

Located just 25 miles southwest of Portland, at the base of Oregon’s beautiful coastal range, Hagg Lake offers visitors the best of outdoor recreational activities.

Owned by the US Bureau of

Reclamation (BOR) and maintained and operated by Washington County, the park features numerous picnic areas, two boat launching facilities, a fully-stocked lake for fishing, more than 15 miles of hiking/biking trails and observation decks for wildlife and bird watching.

Since the creation of Henry Hagg Lake in the mid 1970’s, Washington County and the BOR have shared a commitment to make the park user-friendly to every visitor.

Hiking and Biking
Enjoy a view of the lake and nearby foothills as you bike or hike 15 miles of easy to moderate trails following the edge of the lake. Head out to the perimeter road for an additional 10.5 miles of low traffic, paved bike lanes.

You may catch a glimpse of some of the wildlife that make their home around the lake — elk, deer, coyotes, bobcats, osprey, bald eagles, red-tail hawks, beavers, squirrels and a wide variety of songbirds and waterfowl.

Four large group picnic areas welcome your large party or company function. Two group sites accommodate 80 people and two covered pavilions can seat 200. Small private sites with tables and barbecue grills are found throughout the park.

Two 800-foot long hard-surface boat ramps with launch and recovery floats provide easy boat access to Hagg Lake. Rent a motorboat, canoe, kayak or paddleboat at Boat Ramp ‘C’. The west end of the lake is a no-wake zone to accommodate sailing, rafting, canoeing and trolling. For water skiing, jet skiing or motor boating, the east end allows speeds up to 35mph.

Most of the lake’s shoreline is accessible for swimming. Be sure to swim with a buddy, as there are no lifeguards or officially designated areas for swimming.

Oregon Department of Fish and Wildlife stocks the lake with rainbow trout. Fish from the bank, a boat, or the fully accessible 260-foot fishing pier. The lake also contains Bullhead, Yellow Perch, Bluegill, Crappie, Large and Small Mouth Bass.

Go west on Highway 8 through Hillsboro to the Forest Grove junction with Highway 47. Turn left onto Highway 47 for 5.9 miles to the Hagg Lake/Scoggins Valley Park signs. Turn right at the signs and drive 3.7 miles to the park entrance.
