Because you can often find bait and current around jetties, these are some of the most popular places to fish. This might make you wonder: What is the purpose of a jetty? A jetty protects the shoreline of an ocean body by acting as a barrier against currents, tides, and waves that could cause erosion.
You now know why jetties can be good places for fish to be found and what the purpose is of a “jetty”. But what exactly is a “jetty?”? A jetty simply means a structure that is extended into a lake, sea, or river to affect the tide or protect a harbor. Jetties can be found at harbor entrances, lagoon outlets, near openings of passes, and at the mouths of tidal river channels. A jetty is a structure that extends from the shore into the water and is usually made of concrete, earth, or stone.
Jetties can be found in a lake, on a river, or on the beach. What are jetty structures on the ocean and beaches made of? They are usually made from concrete or piles of stone. They are placed along the shoreline or at the beach’s entrance to provide protection against the elements.
A jetty redirects or stops the longshore current to stop erosion. A breakwater, on the other hand, is built into the sea to create a safe harbor, marina, or anchorage for vessels and protect the coast from strong swells.
You won’t have to wonder “What’s the point of a Jetty?” if you spot one while you’re on the beach, hopefully catching some fish.
