This summer, Parks Canada staff removed approximately 15 human-made rock structures from the Kootenay River in Kootenay National Park to restore natural water flow and keep fish safe.

We know these rock stacks and dams often come from a place of curiosity and enjoyment — but they can have serious impacts on river life.

Even small rock dams can:

• Block fish from swimming to important habitat;
• Trap fish when water levels drop;
• Disturb sensitive riverbeds and eggs.

The Kootenay River is home to special native fish, including Bull Trout, Westslope Cutthroat Trout, and Mountain Whitefish. These species rely on free-flowing water to survive.
