Work is underway to make changes to Nova Scotia's Avon River to allow freshwater to be pumped to Ski Martock for their snowmaking guns. For years, water has been pumped from the river to the ski hill, which is located near Windsor. But in March, a federal ministerial order stated gates at the river causeway were to be kept open for longer periods to allow for the passage of fish. As a result, water levels receded drastically and there was no way water could be pumped to the hill.
