Crappies dieing on whaletail lake

[dakids]

I took my parents out to Whaletail Lake in carver county today.  There were thousands of dead and dieing crappies.  Some were very large ones, pound plus.  We didn't see any other types of fish.  The water was pretty brown.   I also called the DNR and informed them about the fish dieing.  Has anyone seen this happen to other lakes?  What is the usual cause?

i called the dnr this year about lotus lake in chanhassen, hundreds upon hundreds of dead sunfish on the shoreline

Any idea what this is caused by and is there any solution?  Sad to see a massive kill off.  I am sure it is some kind of parasite.  It can't be that the water is too warm.

no idea i think that it is some kind of parasite, but the crappies on lotus didnt die off just most of the sunfish, but theres to many in the lake the way it is so i aint to concerned

This is the information from the DNR.  It's Columnaris Disease.  It sounds like it's pretty common when the water starts to warm up after the stress of spawning.
