From the Milwaukee Journal Sentinel:

Even as the federal government insists its electric fish barrier is working just fine, evidence of Asian carp above that barrier continues to roll in.

With no fanfare, the U.S. Army Corps of Engineers posted on its website this week news that nine water samples taken above the barrier in recent weeks have tested positive for the giant, jumping fish.

Join the Invasive Crayfish Collaborative for an exciting webinar featuring Dr. Chris Taylor from the Illinois Natural History Survey who will provide an overview of midwestern crayfish habitat requirements, feeding, reproductive biology, and life-history.Crayfishes in the Midwest occupy almost every type of aquatic and semi-aquatic habitat in the region. They function as critically important components of those ecosystems and in many cases represent a majority of invertebrate biomass. As “keystone” species, understanding their biology and roles in ecosystems is critically important. Register for the webinar at InvasiveCrayfish.org/events1 Or the link in bio.
