Current Conditions — Is Bow River at Calgary clear to fish today?
Spring runoff — challenging conditions
Flows are about normal for this time of year. Even when that looks normal for late spring, water is often fast and discoloured on freestone rivers. Tailwaters and spring creeks are usually better options until this drops and clears.
Avoid wading in heavy current — fish from the bank if you go at all.
