Steady rain over the water today, with hardly a ripple anywhere with pressure climbing. The fish at Mason Lake are likely to sit near windblown banks where food collects. Expect the better fishing from the day. Give the likely spots time before moving. The autumn feed-up is on; baitfish areas are the key.

In Washington, Mason Lake falls inside King County. What surrounds it is farm and woodlot. The water covers some 32 acres, so pick a bank rather than trying to cover it all. Riverbend sits 9.8 miles from here and is the nearest stop. Renton sits 31 miles out, and it is the nearest city worth the name. This one sits near enough to a boundary to be worth checking.
There is no published depth for this one, so start shallow and work out. On a natural lake the weed line and the shelf beyond it do the work. A soft bed grows weed late into autumn, which keeps fish shallow. King County records list Chum salmon, Coho salmon, Chinook salmon and sockeye salmon among the fish reported. Protected fish appear in the records for this area, so treat the list as information, not an invitation. At Mason Lake the water rewards a slow, careful approach.
Expect August near 58°F and December near 29°F on the long-run figures. Neither winter nor summer shuts things down for long. It is not guaranteed even in a cold spell, so check yourself. Spring and autumn carry the year; summer squeezes it into the ends of the day. The season on Mason Lake follows the weather closely.
Public data does not answer the access question here. You can camp half a mile off, which suits an early start. There are toilets mapped about half a mile away. Trout here take small spinners, spoons and, where fly water allows, a nymph or dry. Local rules can differ across the county line, so check where you stand. Where tickets apply, they are sold in the nearest town rather than on the bank. Failing this one, try Little Kulla Lake, 0.4 miles away. Signs at Mason Lake carry more weight than any list.
