We were at Wolford this spring, while talking to Jeff from the Campground Jeff invited me to rdie along to check the DOW nets placed to catch Pike.
The next morning I rode along we went into the inlet and checked the 8 nets that DOW placed there. On this day the nets had about 20 Northerns all in the 18-24" range. According to Jeff the week prior they had been catching 50-60 every time they checked the nets which was every 3 days.
Long story short there are a few northerns, at least in the spring they gathered in the inlet to spawn.
FYI Lew I have a new plan for us if we fish the Wolford Ice tournament again. I saw some tourny winning Rainbows and Browns, on this trip and I marked my map to the areas we found them in.
