A barrier meant to keep invasive Asian carp out of Lake Decatur is again in place after it was damaged during bad weather in February.
The (Decatur) Herald & Review reports (http://bit.ly/Y1jk3E ) that the 4-foot screen has been placed back on top of a dam.
The barrier was installed in January but failed a month later when part of the screen detached.
Jerry Stevens is the city’s engineering services coordinator. He tells the newspaper that design changes were made to strengthen the barrier.
He says it will be able to withstand ice and debris.
The invasive carp are a menace to aquatic food chains and are making their way up the Mississippi River. Millions of dollars have been spent to keep them from rivers and lakes farther north.
