The Elk watershed (HUC 05050007) covers an area of approximately 1,500 square kilometers in southwestern Alberta, Canada. The watershed is primarily mountainous and is dominated by the Rocky Mountains, which contribute to the hydrology of the region. The watershed receives significant snowfall, with maximum snowpacks typically occurring in March. Surface water in the watershed is primarily fed by snowmelt and precipitation, which flows into the Elk River and its tributaries. The watershed contains several reservoirs, including the Spray Lakes Reservoir, which supplies water for hydroelectric power generation, irrigation, and recreation. The reservoirs are monitored for water quality and sedimentation levels. Interesting climatic facts include the high precipitation rates in the region, which can lead to flooding and landslides, as well as the warming trend observed in the region over the past few decades.
