| Summary | We wanted to find out how changes in autumn rainfall and winter air temperatures affect icing formation at Baker Creek, as it is representative of the seasonal runoff patterns that occur throughout the North Slave Region. Daily meteorological data from the Yellowknife Airport were used to determine trends and changes in autumn rainfall and winter air temperatures over a 37-year record. Streamflow at Baker Creek, measured upstream of any stretches of the water course that have been altered, was used to calculate the total winter runoff. The established relations were plotted to show how the winter runoff has changed with autumn rainfall through time. We also compared these results with the frequency and distribution of historical icing over a 28-year interval using satellite imagery and with the number of periodic winter warming intervals each winter. |
| Local Relevance | The potential for increasing autumn rainfall in the North Slave region of the NWT has caused concerns of winter overflow (aufeis) events. Such events could be disruptive to local safety. |
