No stocking history on the WDFW Lena Lakr webpage but...It's been a long while, but my recollection is that there is not a lot of fly fishable shoreline, so if you have a packraft or float tube to get out on the water you will likely fare better. Can't remember if the lake has cutthroat or brook trout, but they are small and should be hungry, and therefore catchable.
I think you’re pushing your luck for ice free in 2 weeks. Wolcott indicates lake was stocked with rainbow, cutthroat and eastern brook. But you may be fishing only ice free margins.In two weekends, I'm going on my very first backpacking trip. I'm also brand new to any type of fly fishing.
Do you guys think Lower Lena Lake could be a place that someone could catch some fish in mid May?
