Scientists artificially refrigerated a salmon stream in Nova Scotia during last summer’s record heat wave. Hundreds of migratory and river-dwelling fish basked in the cold-water flows pumped into the river from a nearby groundwater well. The addition of cold water to the Wrights River was part of a Dalhousie University study conducted to determine if adding colder water to streams that become dangerously warm for trout and salmon during prolonged heat waves can help keep the fragile fish alive.
