I hiked up to Mason Lake yesterday near Snoqualmie pass. I had been to the lake once before and seen a fish in it, yesterday was not so lucky. I brought my raft and paddled around over half the lake without any sign of fish whatsoever. I was using spinners and tried different depths and a few different speeds to no effect. Another hiker tried fishing for a while with no luck either. According to the WDFW the lake was last stocked in 2010. Either it's fished out, or they're hibernating.
Oh, and my raft sprung a leak and one of my paddles that had a crack in it broke as I was trying to get to shore before getting dunked. Luckily I made it just as it started to downpour. Not the best day of fishing.
