Last week Port Huron City Manager, James Freed reported that they received several calls about dredging the canal as there is a sandbar forming and blocking the entrance of the Black River to Lake Huron. City officials had been waiting until a permit was issued from the DEQ or the Army Corps of Engineers. The City of Port Huron has a standing permit to dredge on August 1st. They worked with both agencies to expedite the process, and now, weather permitting, the Black River Canal will be closed to watercraft on Monday, July 22nd and Tuesday, July 23rd from the Tainter gate, located east of Gratiot Avenue, to Lake Huron. The closure is necessary to enable dredging of sand accumulated at the mouth of the canal.
