Water & habitat

Bottom type, turbidity, depth and current matter. A discharge number alone cannot describe drum habitat along a wide river channel.

Seasonal life

Spawning occurs during warmer periods; males can produce characteristic grunting or rumbling sounds associated with breeding.

Read the water, not a fishing score. Gauge readings describe one monitoring location. They do not prove fish are present, predict a bite, establish safe access or replace current fishing rules. Check the observation time and the specific stretch of river.
