I fished Langlois for the first time today. It is a real pretty lake nestled in a large grove of trees, with very few houses, and one heck of a lot of downed timber along the shoreline (probably from the logging of the eastern Puget Sound foothills in the 1915-1930 period).
Many people were on the lake today, but it was not crowded, and all seemed to be hitting fish. My partner and I were not so lucky, and we had a hard time getting any fish to hit, but we did find out to our pleasure that "anything green" fished herky jerky with a sinking line would work. I have success on both a green chenille carey special and an olive beadhead wooley bugger, but the fish were small. I found that my fast sinking tip seemed to work deeper and into the fish better than my buddy's intermediate line.
We did hear that a guy with a depthfinder got a reading of 98 feet near the middle of the lake, so the hydro contours on the map are correct at least in extent.
On the real downside, we found that a YWCA camp occupies the north and west shores of this lake, and all the folks fishing this morning got mobbed by a flotilla of young girls in aluminum canoes. I am surprised that more fish did not die from the noise. It almost drove us from the lake.
