Water Structure & The Art of Survival

Largemouth bass, one of the most popular game fish in North America, are known for their elusive behavior and impressive adaptability in various aquatic environments. To thrive in lakes and rivers, these cunning predators rely heavily on the use of underwater structures. This article explores how largemouth bass use different types of structure in both lakes and rivers for survival, feeding, reproduction, and schooling. We will also delve into the influence of water currents and the position of the sun on the strategic placement of these bass in their chosen structures.

The Importance of Structure

Water structures, whether natural or man-made, serve as essential components of a largemouth bass’s habitat. These structures provide hiding spots, shelter, and an advantageous vantage point for ambushing prey. Moreover, these underwater features help bass conserve energy, as they can rest in or near them without being exposed to strong currents or excessive sunlight.

Types of Structure

Largemouth bass are often found lurking in and around submerged aquatic vegetation such as lily pads, hydrilla, and submerged grass beds. These areas provide both cover and access to abundant prey like insects, small fish, and crustaceans. Bass will use these vegetation patches to ambush unsuspecting prey.

Rocks and Boulders:
In rocky lake or river bottoms, bass frequently seek refuge in the gaps between rocks or beneath submerged boulders. These rocky structures create a perfect habitat for crayfish, one of the bass’s favorite meals.  Boulders and large rock also take heat from the sun, surface and surrounding waters and maintain it longer than the water around it.  These warm pockets often attract bass and make for excellent targets for anglers.  

Sunken Trees and Logs:
Fallen trees, submerged logs, and brush piles offer excellent cover for largemouth bass. They often inhabit the nooks and crannies of these structures, waiting for prey to pass by. These structures also serve as ideal locations for bass to build their nests during the breeding season.

Docks and Piers:
Man-made structures such as docks and piers attract largemouth bass, as they provide both shade and a steady source of food. Bass can often be found lurking beneath these structures, especially during hot summer days when the sun is blazing.


More so in lakes than rivers, depth is a significant factor in how bass may position themselves in the water column.  If a body of water has little structure in the form of rock, vegetation, current or man made structures, depth becomes a major factor for anglers in locating bass.  Water clarity directly affects the depth bass will position themselves as the impurities in the water create shade at certain depths.  Bass will use shade to ambush their pray, protect themselves from pray as previously mentioned.  As a predator a bass will find shade and structure as a mean to survive, depth can be the best form of survival in certain bodies of water.

Water Currents and Position of the Sun:

The behavior of largemouth bass is strongly influenced by water currents and the position of the sun. Understanding these factors is crucial for anglers looking to improve their success rates:

Water Currents:
Largemouth bass are opportunistic feeders, and they use water currents to their advantage. When water is moving, bass will often position themselves on the downstream side of structures such as rocks and submerged logs. Here, they can patiently wait for prey to be carried to them by the current, expending minimal energy.

The position of the sun plays a significant role in where largemouth bass choose to hide. On sunny days, bass will seek out shaded areas provided by structures like docks, overhanging trees, or aquatic vegetation. They do this to avoid the intense sunlight, which can make them more visible to both predators and prey.

Reproduction and Schooling:

During the breeding season, largemouth bass become highly territorial and protective of their nests. They often choose to build their nests near submerged structures like vegetation or sunken logs. After the eggs are laid, the male bass guards them vigorously.

When it comes to schooling, largemouth bass are not known for forming large schools like some other fish species. However, they do exhibit a form of social behavior. Young bass often congregate in loosely organized groups near structures, where they can find safety in numbers. This behavior can make it easier for anglers to locate and catch multiple bass in one area.


Largemouth bass are skilled navigators of their aquatic environments, using various structures to their advantage for survival, feeding, reproduction, and schooling. Understanding the types of structure they prefer, as well as how they react to water currents and sunlight, is invaluable knowledge for anglers seeking to catch these elusive and prized fish. So, the next time you’re out on the water in pursuit of largemouth bass, keep in mind the vital role that structure plays in their lives, and you might just improve your chances of a successful catch.
