sunka27,

First off, I apologize for not seeing your question earlier. Not real sure how I missed it!

Early spring white bass die offs are not all that uncommon in Kansas reservoirs. The usual cause is Columnaris. Healthy white bass normally fend off Columnaris, but when the fish become stressed they become more susceptible. Kansas die offs usually occur when fish are stressed from spawning activities. Spawn stressed fish, warming water temperatures, and sometimes increased population density open the door for Columnaris to take hold of weakened fish. The KDWPT Fish Bio for Elk City investigated the die off and estimated 5,000 white bass were impacted.
