Well, if it's the middle of May, and you look out the window to see all sorts of Starcraft Islanders padding about at 1.5mph, then it must be a Salmon derby? Yes, that is correct.
More boats out there, right now, than I've seen all springtime, so far. Large sport fisherman to smaller 16'ers rigged for Salmon trollng, very slowly glid'n along across the gentle waters.
Yesterday's weather was about as wicked wavy as it ever gets around here, so today's weather is pretty much perfect for a fishing derby. There's like about ten trollers out there right now, padding about, and not even a single boat, anywhere, moving faster than 1.5mph. Now that is unusual.
There's no webcam in this area of the lake, so's you'll just have to take my word on this.
