Aquatic ecosystems are more than just homes for fish. Our mountain rivers form the headwaters of major watersheds (Bow, Red Deer, Clearwater and North Saskatchewan). They provide clean water and a source of life within a variety of settings.

These aquatic ecosystems are the richest pockets of life in Banff National Park - and, in many cases, the most altered. In the park's past 100-plus years of management, park waters have been stocked with exotic fish, natural channels re-routed and waters polluted locally or indirectly from a long, long away.
