At one time, many native Bonneville Cutthroat Trout lived in East Canyon Creek.
These fish are now much less common, due in part to current and past land and stream
uses.
The stream is warmer, wider and more shallow now, because the woody vegetation that stabilizes the stream banks and provides shade has been removed in many places.
Runoff to the river also carries many types of pollutants, including:
• loose soil from disturbed areas;
• pet and livestock waste;
• metals, oil and grease from our roads and parking lots;
• nutrients (fertilizers) from lawns and agricultural areas.
