• Where to Fish on Larson Lake

  There is no published depth for this one, so start shallow and work out. Look for the band where the shallows give up and the bottom falls away. Where the bottom changes texture, fish gather; find that line. Records held for Mason County cover Chum salmon, cutthroat trout, Coho salmon, largemouth bass and rainbow trout. Some of the species recorded here are protected or tightly regulated, so check what may be targeted before you fish. Larson Lake repays a walk before the first cast.

• Seasonal Patterns

  In an average year August sits at 63°F and January at 39°F. Fish stay active all year, but they move with the heat. Heat pushes fish deep from June onwards, so start early. April and May are the settled weeks, with October close behind. That shapes the year on Larson Lake. Wind direction changes which bank is worth fishing.

• Tackle & Baits

  Public sources are silent on who controls the bank. There is a ramp at Union River Boat Launch, 0.9 miles out. Parking sits half a mile out, which makes for a walk with tackle. Toilets are half a mile away, which matters on a long session. Local rules can differ across the county line, so check where you stand. A polite question at the farm gate opens more banks than anything else. Should this one be busy, Oak Patch Lake is 3.2 miles off. Signs at Larson Lake carry more weight than any list.
