The Central Canal appears to have sprung a leak. The seven-mile canal was built in 1836 and runs from Broad Ripple to 16th Street. It provides drinking water to 60 percent of the city. Yep: Most of us drink that stuff. It seems the roots of some upended trees near the art museum have breached the canal’s banks, allowing water to seep into the nearby White River. If left unattended this could cause a water shortage, or drain the canal altogether. Work has begun to repair the leak, closing the towpath between Michigan Road and Butler University.
