Fishing and Water Discharge

WATER DISCHARGE
Why do fishermen care about water discharge?  How can fishermen benefit from having this data?  Water discharge, or streamflow, is a terrific indicator of how fast or slow water is moving in a river, stream or reservoir.  This helps fishermen determine whether a location is fishable to begin with.  Understanding discharge can also help fishermen determine the right tactics for high or low discharge rates. Use FISHBUOY Photos to create a history of discharge rates vs. fish catches to determine your optimal flows.

HIGHLIGHTS

WHY UNDERSTANDING DISCHARGE WILL HELP YOU CATCH FISH

Water Preference

Fish will favour their biological preferences to water flow.  During high discharge, look for seams and slower moving pockets of water.

Feeding Behaviour

High discharge rates impacts the amount of time your bait is in a fishes visual strike zone.  Make it easier for fish to see your bait by using larger baits or higher vis colors.  (See Great Lakes Spawn Tying Guidelines)

Seasonal Trigger

Pay attention to signifcant increases in discharge rates around the time of spawning periods.  High stream flows flush sweet water into large water bodies and can act as a trigger for pre-spawn migrations.
