Flat light and a covered sky today, with a gentle ripple from the E with a softening glass. Activity on Bertha Lake should centre on shallow cover and weed edges. If you pick one session, make it the morning. Stay mobile and follow the activity. Autumn fish are feeding up and less fussy than in summer.
The bites are excellent now

Bertha Lake sits within King County in Washington. Height above sea level is 4,308 feet. The water measures roughly 2 acres, so nothing here is far from anything else. Our King County list holds plenty of bigger water. Gold Bar sits 22 miles from here and is the nearest stop. Bellevue sits 45 miles out, and it is the nearest city worth the name. The nearest boundary is well away, so one set of rules covers the water.
Our records hold no depth for this water. Still water like this holds fish on the edges rather than out in the open. This is a lake, so the margins and the first drop matter most. Across King County, recorded fish include Chum salmon, Coho salmon, Chinook salmon, sockeye salmon and yellow perch. At least one recorded species is protected in parts of its range; read the local rules before targeting anything. Bertha Lake fishes better once you know its edges.
August runs about 58°F on average, December about 26°F. Most months fish reasonably, given the right weather. Hard water here is never dependable, so check for yourself before stepping out. Late winter often fishes better here than midsummer does. It holds true on Bertha Lake more years than not.
The rules here are undocumented as far as public sources go. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. For the trout, small spinners and a box of nymphs cover both approaches. A landowner's word beats anything printed elsewhere. A polite question at the farm gate opens more banks than anything else. Jakes Lake sits 0.7 miles off and takes the overflow. What applies at Bertha Lake may have changed since it was mapped.
