Kidney Lake, WA

When I had my own car my junior year of High School I started to explore fishing opportunities in Southwest, Washington. There was an article written in the Columbian for places to try opening weekend. On that list was many lakes I knew about but also Kidney Lake. Over the next two years I would fish Kidney Lake heavily. I would get out of class at 2pm drive 45min down the 14 from Vancouver and have my pontoon on the water before 3:30. Fishing this lake on average three times a week until the rivers opened in June I know where the fish sit and how/what they bite. Did I mention my birthday is the same weekend as opening weekend for lakes in Washington. Once at school in Seattle my friend and I made it a tradition to drive down every year for a weekend on the lake.
Kidney is not some glorious lake. It is small (11acres), power lines stretch across, its littered with beer cans and worm cans, but it fishes well in late spring and holds triploid trout. In case you don't know what a triploid is, they are genetically altered to eat instead of breed, stocked over a pound they grow to 20# if left for a full year in good conditions. Not to mention brood stock are planted at 5 & 10 lbs. These fish are what draw me to this lake.
There is a inflow on the North side of the lake and outflow on the Southwest corner. Through the channel the lake is 60+ feet deep. The other side of the lake is shallower and even warmer. You either want to fish the stream channel or the middle of the other half of the lake. The triploid start in the channel and move to warmer water by mid-May.
Once again this year, three of my friends and I headed out to the lake Saturday of opening day (it was crowded) and we set on the water, them in a raft and me in a float tube. Trolling a worm behind a woolly bugger works well but just as well works a woolly bugger with a carey special. You can use either floating or sinking line, depends on how hot the day is, and let you line drift behind you as you mingle around the lake. I caught one of my nicest fishing eating a sandwich, sitting still, and line sitting 10' below me. We had a good day catching 40-50 fish between the four of us.
If you don't care about fishing next to a floating busch light can, then this is a good lake to fish.

Note: If you want to fish from shore a bobber with a worm works on overcast days about 30" down and egg weight, swivel, and floating powerbait on hotter days off the bottom.
