Three key questions are identified and answered in this paper. Firstly, have the average annual temperatures in the Prince George Region changed in recent years? Secondly, have the seasonal flow rates changed for local waterways? Lastly, have the timing of the annual flood cycles in the Prince George, British Columbia changed? By reviewing data from local weather and hydrological monitoring stations, this paper identifies that the average annual temperature in Prince George, British Columbia has not only increased but also shifted to a pattern of warmer winters and cooler summers. The flow rates for the region were seen to have been altered as well, indicating increased flow rates in the winter and early spring and decreased flow rates in the summer and early fall. The magnitude of flood frequency events such as the 10, 25 and 100 year flood occurrence does not seem to have the increased in recent years.
