How Do Underwater Structures Affect Fishing?

Knowing About Under-ground Structures Helps You Catch More Fish!

This article is a continuation of some interesting points in Tim Lilley’s book, Ultralight Fishing. *

The previous article is here:  Catching Fish with Ultralight Tackle

Lilley takes pains to explain the value of having a topographical map of any body of water you plan to fish.  Each body of water has unique structures that will affect fishing.

Structures That Affect Fishing

Topographical maps show “the lay of the land” — in this case — underwater.  The map will show shallow areas versus sharp drop-offs (into deep pools).

This is important because fish move into deep pools when the shallow water gets too warm and they stay in deep pools during cold weather (because it is a consistent temperature).

Smallmouth Bass are notorious for living in submerged rock piles.  If your topographical map indicates a rock formation, it’s an area that you can investigate.

Fishing Underground Structures

Most fishing books talk about finding predatory fish.  Why?  If you are going after a predatory fish, he’s larger than his supper, thus a bit higher up the food chain.

Also, since these predators are looking for a “meal deal,”  they are hungry and likely to attack an attractive bait or lure.

Your task is to figure out what he’s in the mood to eat  — and serve it up on the end of your line.

Using Your GPS While Fishing **

When you are successful in a day’s fishing, it’s a great idea to use your GPS** to mark any hotspots you find.

Lilley also makes a point that with a GPS device, you are never really lost on a large body of water (or anywhere else).

Matching Lures with Structures

Lilley’s suggestion for fishing around a deep drop-off is to use a plastic worm.  He lets it free fall to the bottom.

Because it only weighs 1/4 ounce,  it will take a long time for the worm to drop, thus having the lure in front of  fish for the greatest time, while the fish decides how to react!
