The City of St. Albert plans to add a couple of new tools to its water-management tool belt over the next few years to counteract problems caused by the local beaver population. Melissa Logan, the city's environmental coordinator, said staff will install pond levellers in high-priority spots throughout Carrot Creek and the Sturgeon River, starting this summer. Unbeknownst to the estimated 16 individual beavers who call these rivers home, pond levellers allow water to flow through dams to prevent flooding, Logan said.
