About Steel Lake

Steel Lake is a 46-acre natural lake in Federal Way, Washington, with a designated public swim beach inside the city-run Steel Lake Park on its southern shore. The City of Federal Way's own parks listing names swimming and a beach among the park's amenities, alongside a boat launch, playground, and picnic areas, making this swimming hole an in-town lake to swim in.

The lake sits in a residential part of Federal Way, mostly ringed by homes, with the 52-acre Steel Lake Park occupying the southern shoreline. The park combines a lakefront beach and lawn with active-recreation features (sand volleyball, skate park, ballfields, horseshoe pits) and picnic shelters.

Swimming at Steel Lake

Swimming happens off the designated beach at Steel Lake Park. News reporting describes the water near shore as shallow at first but dropping quickly from about 0 to 5 to 10 feet a short distance out, then to a maximum depth of 24 feet toward the center; the water itself is characterized as cold, deep, and very murky, with a dense mat of Eurasian watermilfoil weed on the bottom in places. The lake is also used for fishing, kayaking, and paddleboarding.

How to get to this swimming hole

Steel Lake Park is at 2410 S 312th St, Federal Way, WA 98003, about 1.1 miles from central Federal Way per the site's location data; the park has an on-site parking lot.

Parking: On-site parking lot at Steel Lake Park, per the city's official parks page.

The hike in

Time on foot: Well under 5 minutes' walk from the parking lot to the beach.

No hike is needed; Steel Lake Park has an on-site parking lot with direct access to the beach and lawn area. The park does have a walking trail around the grounds, but it is a park amenity, not a required approach route to the swim beach.

Plan your visit

Bringing kids

OK with supervision

It's an official, easy-to-reach city swim beach, but news coverage (Federal Way Mirror, July 2026) reports no lifeguard mentioned, water that drops from wading depth to 5-10 ft within a short distance of shore, cold and very murky water, a thick Eurasian watermilfoil mat on the bottom that can entangle swimmers, and multiple drownings at the lake including children in 2020 and 2026. Supervise kids closely and keep them near the shallow shoreline.

Parking

Free

On-site parking lot at Steel Lake Park (2410 S 312th St, Federal Way, WA 98003); no parking fee is listed on the city's official park page or in local news coverage.

Restrooms

Yes

Restrooms are listed as an on-site amenity at Steel Lake Park on the City of Federal Way's official parks page; exact location/type (flush vs. vault) not specified in city listing.

Water clarity

Often murky

Federal Way Mirror news coverage (July 2026) describes the water near the park beach as cold, deep, and very murky, with a dense Eurasian watermilfoil weed bed on the bottom; this matches a 2010 Federal Way Mirror report of a milfoil outbreak in parts of the lake. No firsthand visitor reports on water clarity were found this pass, so this rating rests on the news sourcing rather than firsthand accounts.

Hours

Dawn to dusk unless otherwise posted (city-wide Federal Way park hours; dawn = 30 min before sunrise, dusk = 30 min after sunset).

Swim smart

News coverage documents multiple drownings at Steel Lake (including in 2012, 2020, and 2026), attributing risk to the cold, murky, and quickly deepening water; a thick Eurasian watermilfoil weed bed on the lake bottom has also been flagged as an entanglement hazard for swimmers, especially children. Periodic bacterial (sewage) contamination has forced temporary swimming closures.

Rules: Park hours are dawn to dusk unless otherwise posted. Swimming has been temporarily banned during documented bacterial contamination events (e.g., a 2022 raw-sewage release closure); no-inflatables rule applies to picnic/rental areas; the lake has a seasonal fishing closure to protect fish populations, one of only ten such-protected lakes in King County.

On the water

KayaksCanoesPaddleboardsMotorboats

The City of Federal Way's official park page lists a boat launch at Steel Lake Park, and Federal Way Mirror news coverage (July 2026) describes the lake as 'a popular place for swimming, fishing, kayaking and paddleboarding.' No horsepower limit, no-wake zone, or electric-only restriction could be confirmed in sources found this pass; a park rental-booking page separately notes a no-inflatables rule, but that appears to apply to inflatable amenities at reserved picnic sites, not to on-lake watercraft.

Backstory

The lake is named for Arthur Steele, an early-1870s area settler. In 2022 the city proposed developing an 11-acre lake annex for municipal operations; the proposal was abandoned in 2023 after public opposition.
