City crews have begun efforts to clean up debris along the Elbow River that accumulated after floodwaters swept through the city in June.

More than 60 locations have been identified by crews as containing significant amounts of debris, including large trees and construction materials.

Some areas of the river pathways could be closed during the cleanup because of the size of the equipment needed to remove the debris.

While the city is hoping to have the job done in two weeks, it's possible the task could take longer.

Cleanup efforts will begin on the Bow River later this year.
