Hudson Bay watershed

The Hudson Bay watershed is a large land area in northern North America whose rainfall and snowmelt drain into Hudson Bay, a massive inland sea. Covering parts of Canada and the northern U.S., it includes many rivers and lakes funneling water toward Hudson Bay. This region influences local ecosystems, climate, and water flow, playing a vital role in the natural landscape and supporting diverse plant and animal life. Its health and changes can impact larger environmental systems, including climate patterns and freshwater availability across the Arctic and sub-Arctic regions.
