Somewhere in the lake the fish were schooled and prone to attack a lure. You got lucky finding a small group in a short period of time which happens to me a lot ice fishing. No fish on sonar = no fish present to bite.

take it for what's it's worth
So , I’m guessing you’re saying the few hours of sunlight on the shallows didn’t warm the water enough to cause the movement of the school to move shallow ?
When I used my to fish out of my boat weekly . I found I used the temperature on my old Cuda depth finder more during late winter and early spring more than the depth or fish indicator features .
I’ve seen the water temps rise as much as five degrees or more in coves , especially those with a southern exposure that would get sun most of the days .
I used temperature to locate the fish . A few degrees makes a lot of difference to a fish , IMO .

I’ve had it happen at the town pond where the bite would be better in the late afternoon after a day of sun warming the shallows .
Water temps in a small pond fluctuate more than in a bigger reservoir. That’s why I fish the pond more in the winter than I do the bigger reservoirs or the creeks .
I could be off base , but it’s worked for me over the years .
But I don’t let it keep me from going and trying .
And I only fish on days that end with a Y .
