“It’s safe to say (Lake Calumet) has been historically underutilized,” said Dustin Calliari, the CMAP associate planner who’s leading the agency’s efforts there. Though there’s been an uptick in freight movement on the south end of Lake Calumet, and particularly at the port district’s Iroquois Landing dock area at the mouth of the Calumet River, the port is in need of “rejuvenating,” he said.
