A question for Elite Bass Masters

[Bergen Angler]

Before the cold front, male bass were hovering over the nest, female were cruising, some appeared to be guarding the nest. I can see some nests with crappies.

Last 2 days, all I see is empty nest, after the cold front.

Does this mean cold front push the bass back into deeper water? I don't see any fry and just empty nests. I might see a few bass cruising very sluggishly.

I don't think it means post spawn rather cold front made the pre spawn condition?

I would love to hear from bass masters as I have no clue what is going on.
Thank you.
