As I understand it, the effluent is beneficial for insects, the main food for trout. Many rainbow trout actually leave the Bow to spawn in tributaries of the Highwood River (right about now until mid June). Brown trout are present all year, and spawn in the Bow in the fall.

The benchmark for bragging-sized trout in North American streams is 20 inches. On most streams, 20-inchers are rare or nonexistent; on a few streams they are occasional, pleasant surprises. On the Bow River below Calgary, they are expected. The size of its fish has been perhaps the only constant on this river known for both great fish and great unpredictability. The Bow below Calgary produces larger average trout than virtually any other stream in North America. It continues to give capable fly-fishers many rainbows and browns between 20 and 24 inches long.
