How to Fish Upwelling Around Offshore Structure

When current hits offshore structure, cold nutrient-rich water rises toward the surface. That localized upwelling compresses bait and predators into defined zones. This article breaks down which structures create the strongest upwelling, how to read the signs before and during a trip, and how to position and present baits where predators actually feed.
