In the mid 80’s I was fishing at Sturgeon Landing, SK where the Sturgeon-Weir river empties into Namew Lake right on the MB border. We were catching walleye on mister twister tipped jigs when I got a snag. We were wrapping up for the evening anyway so pulled anchor and motored over to try pull the snag from above it. After yanking on the “snag” a few times it slowly started swimming upstream. We followed for a bit but it was clear that I wasn’t even hindering the sturgeon’s motion with my 8lb test walleye setup. I pulled by hand until the knot snapped at the jig head. I have no clue how big the fish was - would’ve been cool see it. They look almost armor plated so would’ve been interesting to see where I snagged it with that small hook.
