With daytime highs around Ottawa to remain above zero for the next few days, one local conservation authority is warning people to stay away from the banks of streams and rivers.
The Rideau Valley Conservation Authority says that the pleasant temperatures are creating "unstable" ice conditions near the region's waterways. "All watershed residents are advised to stay off of the ice on rivers and streams and avoid ice and snow-covered stream banks where footing can be unpredictable," the agency said in a recent warning.
