What type of structure is best for fishing under in fast-moving river currents?

Fishing in fast-moving river currents is most effective in areas known for having eddies and holes formed behind rocks. These structures create a calmer environment where fish can seek refuge from the strong currents. Eddies are swirling areas where water circulates back on itself, allowing fish to conserve energy while still being able to feed on insects and smaller prey carried by the flow. Holes often have deeper water, offering additional protection and a stable habitat for fish, making them ideal spots for anglers.

In contrast, open waters with no obstructions generally provide fewer ideal conditions for fish, as they lack the structure needed for protection and feeding. Fast, shallow areas can be too turbulent for many fish species, pushing them into deeper and more sheltered spots. Areas with little vegetation often lack the cover that fish seek for safety and are less conducive to attracting baitfish, which limits the opportunities for successful catches.
