This one is safely inside the county line.

• Where to Fish on Lake Blethen

  No figure exists for depth, so let the water show you. This is a lake, so the margins and the first drop matter most. The shallow end warms first and pulls fish in ahead of the rest. Public occurrence data for King County names Chum salmon, Coho salmon and Chinook salmon. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. Fish Lake Blethen where the bottom changes rather than where it looks deep.

• Seasonal Patterns

  Long-term averages put August at about 59°F and December near 31°F. Mild ends to the year keep the season long. It is not guaranteed from one year to the next. June to September is hot work, so the first and last hours are what count. Time your trip to Lake Blethen by conditions rather than dates.

• Tackle & Baits

  Our records carry no access rule either way. No made access is recorded, so a short walk in is the likely arrangement. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Check whether a boat is allowed before you tow one. Night access is frequently treated as a separate matter. Upper Lake Blethen, 0.4 miles away, makes the obvious fallback. None of that is settled for Lake Blethen in what we hold.
