Black crappie females produce between 11,000 and 188,000 eggs; white crappie females produce between 2,900 and 91,700 eggs. Eggs for both species hatch
within 3 to 5 days. Crappie fry feed on yolk sac for 3 to 5 days, and then they leave the nest.

So if you have been catching these post spawn females for more than a week, then the babies will be fine. And as I remember, fish don't all spawn at the same exact time. I have caught fish on the same spawning areas from Late March untill mid May in previous years, females and males alike, and females having and not having eggs throughout that period.

Also, if the AGFC didn't manage the water levels on the lake, did you ever stop to think that if the water topped the dam, it might wash out, thus draining the entire lake. And then what would the fishermen have to say?

They are danged if they do, and danged if they don't.
