“Because of this, engineers have been encouraged to develop just about any solution to keep carp at bay — or out of one.One such solution was the electric barrier in the Chicago Sanitary and Ship Canal, which was meant to keep Asian carp from swimming through the CAWS and into Lake Michigan. Of the identified 18 points of entry into the Great Lakes, the Army Corps believes the CAWS point is the most critical.
The barrier consists of three electrodes arranged in a line. These electrodes power a barrier much like an electric fence for dogs. Fish swimming into it receive an electric shock sufficient enough to stun them and keep them out — in theory. According to a report issued by the Army Corps in December, 2013, the barrier is effective against adult carp, but smaller fish of two to four inches long were able to find a loophole……It’s a big risk to take when plans require billions in funding. Still, an appropriate plan may pay off in the long term. Recent studies suggest that controlling the spread of invasive species already present in the Great Lakes can cost up to $800 million annually.”

Climate change is making it harder to manage sand on Chicago’s beaches, with rising water levels, bigger storms, and stronger winds. IISG-funded research led by C. Robin Mattheus and a team of ISGS scientists tracked sand distribution along 18 beaches—offering the first regional, high-resolution assessment of the Chicago shoreline. #SeaGrantFunded
