Scientists from the Northwest Territories’ Environment and Climate Change Centre have reported that water levels and flow rates are unusually low throughout the region. Data collected recently shows that both lakes and rivers are experiencing significant declines, raising concerns about water availability.
Great Slave Lake, for instance, continues to record levels that are “well below average,” remaining below the 90th percentile compared to historical data spanning the last century. This pattern has not changed much since last year, indicating a troubling trend in the region’s hydrology.
Similarly, the Great Bear Lake has reached its lowest water levels for this time of year, which adds to the worrying picture. Rivers such as the Mackenzie and Hay are also below average, emphasizing the widespread impact of these low levels. Notably, the Liard River is similarly affected and is classified as below average, falling between the 75th and 90th percentile.
Interestingly, not all waterways are experiencing these low conditions. Both the South Nahanni River and the Coppermine River have levels that are above average. Some smaller rivers in the Great Slave Lake basin, like the Lockhart River, are also maintaining above-average water levels, while others like the Hoarfrost and Taltson Rivers are showing typical flow rates.
Climate scientists predict variability in temperatures across the N.W.T. this winter. February is expected to be cooler than average in the northern parts of the territory, while the south may see warmer conditions. However, the forecast for March suggests a return to cooler temperatures across all regions.
Recent statistics highlight that cumulative precipitation has been average to well above average, particularly noted in the headwaters of the Peace River, which have seen record rainfall. This might counterbalance some of the low water levels in certain areas.
Understanding the current trends in water levels and temperatures is crucial. As climate change continues to impact our environment, these findings underscore the importance of monitoring natural resources closely. More research is needed to assess long-term implications for ecosystems and communities in the Northwest Territories.
