River floodplains act as nature’s shock absorbers during spring ice breakup, storing excess water released from melting snow and fractured ice jams. As ice fractures and surges downstream, the floodplain’s broad, flat terrain allows water to spread out rather than surge violently, reducing peak flow levels and lowering the risk of sudden inundation in populated areas.
At Sylvia Grinnell, the valley floodplain’s gently sloping banks and interconnected side channels channel the spring swell away from the main river course, protecting trails and downstream infrastructure. The river then flows past the city of Iqaluit—whose name in Inuktitut means “Place of many fish”—underscoring how these pristine waters have sustained local communities for generations.
This natural buffer not only mitigates flooding but also replenishes wetland habitats critical for tundra flora and fauna. In summer, the waters here are so pure that they can be sipped directly from the stream without boiling—a testament to the pristine catchment upstream and minimal human disturbance in the watershed.
Local legend holds that each August, Arctic char returning to spawn act as living filters: as they swim upstream, they absorb impurities in their skin and then carry those contaminants back out to sea upon their departure. Whether myth or metaphor, the tale underscores the community’s reverence for the river’s extraordinary clarity and its vital role in sustaining life on the land.
