MUNSTER, Ind. (CBS) — Chris Spolnik and other locals are keeping an eye on the Little Calumet River, which has been rising and falling.

What they don’t want in Munster, Ind. is a repeat of the flood of 2008, when the river rose over its bank, sending water straight into homes. Since that time, a lot of measures have been put in place to detect rising water levels.

“We’re monitoring the water levels through town since this morning, since the water started rising,” Spolnik, of the Munster Streets Department, told CBS 2’s Suzanne Le Mignot on Thursday.

Back in 2008, mud- and sewage-filled water flooded Jim and Denise Carbone’s house. They’re on edge this week, as they are whenever it rains for a couple of days.

“You feel a knot. You feel very anxious. My tell-tale sign that something might happen is when our sump pump runs,” Denise Carbone said.

At the Carbone house, another major change is the levee wall built by the U.S. Army Corps of Engineers in the backyard.

“It does make us feel a lot more safe,” Denise Carbone says.
