Washington Harts Lake Fishing Pierce County: A Complete

Spanning 109 acres south of Tacoma, this WDFW-stocked freshwater lake delivers rainbow trout plants, holdover bass, and the occasional kokanee run that keep the bite active across most of the calendar. The lake sits near Graham, just off State Route 7, and offers you a public boat ramp, a loop of accessible parkland, and a mixed-species profile that rewards anglers who match tactics to the season. Stocking typically begins in March and runs through early fall, with catchable rainbows in the 8 to 12 inch range planted multiple times each season for your hook to find.

This breakdown covers the species you can target, current WDFW rules, the monthly windows that produce, on-site logistics, and the bait and lure choices that work best for Harts Lake fishing. By the time you finish, you’ll have the kind of working knowledge that turns a guess-and-go trip into a planned outing tailored to your next visit.

Harts Lake’s Setting and What Makes It a Pierce County Standout

Harts Lake covers roughly 109 acres in the unincorporated community of Graham, about fifteen miles south of Tacoma and a short drive from the SR 7 corridor. The lake sits in the Nisqually Basin at an elevation near 480 feet, framed by a mix of second-growth timber, pastureland, and newer residential development. The footprint is small for a regional fishery, but the lake’s depth profile, averaging around 16 feet with a couple of deeper pockets near the south end, gives it just enough thermal layering to hold cool-water species through your summer trips.

What separates this water from a typical urban-proximity pond is the combination of a paved public boat launch, an adjoining Pierce County park, and a consistent WDFW stocking program that pushes fresh rainbow trout into the basin from early spring through fall. The surrounding parkland, roughly 40 acres of maintained lawn and shoreline path, gives you legitimate shore access to several hundred feet of fishable bank. Private parcels line the rest of the shoreline, so respecting property lines and staying within the public access zone is part of your experience on the water.

Why the Stocking Pattern Matters

WDFW plants Harts Lake as part of the South Sound trout program, with deliveries that typically begin in March and continue on a roughly monthly cadence into October. Annual plants often total 15,000 to 20,000 catchable rainbows, with supplemental releases of larger fingerlings in some years. That kind of consistent input is the engine that drives your fishery, because natural trout reproduction in a low-elevation Puget Sound basin lake is minimal.

Why the Mixed-Species Profile Changes the Game

Beyond planted rainbows, the lake holds a self-sustaining largemouth bass population, bluegill and other sunfish, and occasional seasonal visitors. Cutthroat trout show up in low numbers, often as strays from nearby stocking programs, and kokanee have been reported in some years when conditions line up. That mix means you can plan a trip for trout and still find action on warmwater species, especially from late spring through early fall.

Species You Can Target and How They Behave in the Lake

Rainbow trout are the bread-and-butter target, and the species most anglers come here to chase. Planted fish tend to school in the upper ten feet of water during the cooler months and slide deeper as surface temperatures climb past the mid-60s. In the first week or two after a plant, fresh rainbows often cruise within a few feet of the surface and will hit a wide range of your presentations, from floating bait under a bobber to small spoons trolled behind a boat.

Largemouth bass are the secondary draw, and they punch well above their average size in a lake this size. Fish in the two to four pound range show up regularly along the woody shoreline, especially near the submerged timber and dock pilings on the western edge. Bluegill, pumpkinseed, and the occasional yellow perch provide steady warmwater action and are a productive option for you when trout fishing slows in midsummer heat.

Cutthroat and Kokanee as Bonus Targets

Cutthroat trout show up in small numbers, often caught by anglers using trout-style gear. State rules require catch-and-release for any cutthroat you encounter, and a single jaw mark or lack thereof is not always a reliable field marker, so treating any unidentified trout with a visible jaw slash as a cuttbow is a safe approach. Kokanee appear in some years, usually in late spring or early summer, and tend to school over the deeper southern basin. When they’re present, small trolling setups with a flasher and hoochie or a wedding-ring spinner tipped with corn can produce limits of fish, though WDFW also requires catch-and-release for kokanee in most South Sound lakes.

Before rigging up, the rule book determines how many of those fish you can actually keep.

Licensing, Passes, and Current WDFW Rules You Must Follow

Every angler 15 and older needs a valid Washington State recreational fishing license, and combined freshwater and saltwater licenses are available for residents and non-residents through the WDFW licensing system. License fees update annually, and the current year’s pricing is published on the WDFW website before the season opener. A vehicle parking pass is the second requirement, and this is where many first-time visitors slip up.

The Harts Lake boat launch and adjoining park sit on land managed by Pierce County, which requires a Discover Pass for parking. WDFW also sells a separate Vehicle Access Pass, but that pass only covers WDFW-managed lands, and Harts Lake is not a WDFW site. A Discover Pass, available as an annual or one-day option, is what you need to legally park at the launch or in the day-use lot.

The Rule Layers You Need to Know

Trout fishing is open year-round at Harts Lake under the statewide rule, but specific daily limits and size restrictions apply to your catch. The current WDFW Sport Fishing Rules pamphlet lists the lake in the South Sound region and sets a standard trout daily limit, with a five trout maximum and a minimum size that varies by year. Largemouth bass are also open year-round, with no minimum size and a daily limit of five fish for your creel. Any cutthroat or kokanee you catch must be released unharmed, and barbless hooks are often the safest way for you to comply with the catch-and-release expectation.

“Check the WDFW Sport Fishing Rules pamphlet for the current license year before every trip, because bag limits, size rules, and gear restrictions can shift on short notice, especially after in-season updates that affect your legal catch.

Stocking Schedule and the Best Windows to Plan a Trip

The WDFW trout stocking list, updated weekly during the planting season, is the single most useful planning tool for Harts Lake fishing. It lists each plant by lake, species, number of fish, and the date of release, and it is searchable by water body on the WDFW website. Treat the most recent plant date as the starting gun for your fresh-fish action, because the first seven to fourteen days after a plant consistently outperform the rest of the month.

Spring opener, traditionally the fourth Saturday in April, draws the largest crowd and often coincides with the year’s biggest plant of catchable rainbows. That first shot produces fast action for shore anglers, and trolling anglers can pick up limits in a couple of hours if the plant has had a day or two to disperse. Late fall and winter holdover fishing is the second-best window, because cooler water keeps trout active throughout the day and the crowds thin out.

Monthly Breakdown of Peak Windows

Window	Best Target	Why It Works
April through May	Rainbow trout	Largest plant of the year, cool water, aggressive fish
June	Trout and early bass	Post-opener plants, warming water activates bass
July through August	Bass and sunfish	Trout slide deeper; warmwater species move shallow
September through October	Trout and late bass	Cooler nights bring trout back up; final plants of the year
November through March	Holdover trout	Light pressure, consistent bites on slow presentations

Recent plant dates shift your best lure and bait choices. In the first week after a plant, fresh rainbows will bite on nearly anything, but PowerBait fished on the bottom or a small amount of nightcrawler under a slip bobber are the two most consistent producers. As the plant ages, trout spread out and school over structure, and small spoons, spinners, and trolled gear start to outperform your stationary bait.

Access, Parking, and On-Site Logistics Worth Confirming

The public boat launch sits at the end of Harts Lake Drive South, off the main park entrance, and consists of a single-lane concrete ramp with a small turning area. Trailer parking is limited to a handful of spaces, so arriving early on a Saturday during the opener is a smart move for you. A vault restroom is available near the launch, and the park’s day-use area includes picnic tables, a covered shelter, and a short ADA-accessible path along part of the shoreline.

Shoreline fishing is possible from several stretches within the park, particularly along the eastern and northern banks where the path runs close to the water. Private homes back the rest of the lake, and trespassing signs are common. Stay on the public side, and you’ll have several hundred feet of accessible bank to work. A Washington State Parks disability pass or a federal Access Pass can be substituted for the Discover Pass for visitors with qualifying disabilities.

Getting There and Stocking Up

From Tacoma, take SR 7 south through Spanaway and Parkland to Graham, then turn west onto 224th Street, which leads directly to the park entrance. From the freeway corridor, take I-5 to the 176th Street exit and head east on Meridian, which brings you to Graham in roughly twenty-five minutes. The nearest tackle shop is a few minutes north in Spanaway, with a couple of larger options within a fifteen-minute drive. Fuel, food, and basic supplies are available in Graham, and overnight lodging is clustered along the Pacific Avenue corridor in Tacoma or in Spanaway for your convenience.

Tactics, Bait, and Lures That Match the Lake

For shore anglers fishing from a park-side bank, the simplest and most effective setup is a slip bobber rig with a 6 to 10 foot leader, a size 8 or 10 bait hook, and a single splitshot about a foot above the hook. Rig a quarter-inch piece of nightcrawler or a PowerBait nugget on the hook, set the depth so the bait hangs two to three feet off the bottom, and cast parallel to the shoreline at fifteen to twenty foot intervals. This is a top-producing pattern for fresh plants and works from spring through fall on your line.

Boat anglers do best trolling small hardware, especially in the days after a plant. A simple trolling spread of two rods, one with a 1/8 oz Koke Krill or Pixie spoon and the other with a Wedding Ring spinner tipped with a small piece of worm, trolled at 1.2 to 1.8 mph over the deeper portions of the lake, covers water efficiently. When bass move shallow in summer, switch to soft plastics rigged Texas-style or a weightless Senko worked slowly along the wooded shoreline.

Special Tactics for Bass and Sunfish

Bass at Harts Lake respond to classic warmwater tactics when you work them right. A green pumpkin or watermelon soft plastic rigged weightless on a 3/0 wide-gap hook, pitched tight to submerged wood, is a reliable producer. For bluegill and other sunfish, a small bobber with a piece of nightcrawler fished near overhanging trees or dock pilings is hard to beat. In midsummer, the warmest hours of the afternoon can actually be the best time for you to target these species, because they move into the shallows to feed.

Limits of the Fishery and How to Plan a Smart First Trip

Harts Lake is a small, urban-proximity fishery, and a realistic first trip looks different from a day at a regional reservoir. Crowds build quickly on the first warm weekend after a plant, and weed growth can slow trolling speeds by midsummer. Warm-water stratification pushes trout deep in July and August, when the bite often shifts to early morning or late evening. Recognizing these patterns is the difference between a productive outing and a frustrating one.

The first two weeks after a plant almost always outperform the rest of the month, so timing your trip to the stocking list is the single highest-leverage decision you can make. On a typical spring plant weekend, an angler who arrives at dawn, fishes a bobber rig from the park shoreline, and switches to trolling mid-morning can expect to catch multiple fish before lunch. In the heat of summer, the same effort might produce a handful of bass and sunfish, and a return visit after the next plant is the better play.

Trip-Planning Checklist

• ▸License and Pass: Confirm your Washington State fishing license and Discover Pass are current before you load the truck.
• ▸Stocking List: Check the WDFW trout stocking page for the most recent Harts Lake plant, ideally within the last seven days.
• ▸Current Rules: Read the relevant section of the WDFW Sport Fishing Rules pamphlet for the current year, including any in-season updates.
• ▸Gear Match: Pack bobber rigs for shore fishing, plus a couple of trolling rods if you have a boat, with PowerBait, nightcrawlers, and a small spoon or two.
• ▸Backup Lake: Have a secondary water in mind within twenty minutes, such as Spanaway Lake or Kapowsin Lake, in case conditions turn tough.
• ▸Weather Check: Verify the local forecast for Graham, Washington, because afternoon winds can make small-boat handling uncomfortable on this size of water.

Recheck the WDFW stocking list and rules pamphlet in the week of any planned outing, because last-minute changes happen. Treat that confirmation as the final step, and your trip stands a strong chance of finishing with a legal catch and a full cooler.

Bottom Line

Harts Lake rewards anglers who plan around the WDFW stocking calendar, match tactics to the season, and show up with a current Discover Pass and license in hand. The combination of fresh-planted rainbows, a self-sustaining bass population, and steady sunfish action makes it one of the more versatile small fisheries in Pierce County. A single visit timed to a recent plant is often enough to make it a regular stop on your fishing rotation.
