Spent past 4 days (and nights till 2am) on Ottertail one wheelhouse and 4 portables. Bite was next to (0). 5 guys 4 day got 5 eye 14" to 17" and 6 perch 7 to 10". Friday -21 on the lake at 3pm. Pressure at 30.90. Did not move a lot but did some moving 30' to 9'. Saturday bit warmer day made it to 11 deg. Same result moved a lot humps, breaks valleys, 40' to 9'. Marked lots of fish in deeper water and some at 9 to 16'. Resort owner talked to half dozen other villages on west end, All having no success. Pressure never got below 30.28 but temps warmed to upper 20' on Sunday. Not a banner weekend but sometimes "that's fishing"
Took a fall on slick icy parking lot week ago, found out today I have 3 fractured ribs. No wonder my right side hurt a bit.
I've had issues with my Eskimo Z-51 reopening holes, getting caught at different parts along the hole ON occasion. Other times it ripped right though. So my answer pretty much sucks but from experience they aren't the best at opening holes.
