Saint Vincent and the Grenadines is made up of steep volcanic islands where short rivers carve valleys, support small farms and feed coastal mangroves. These waterways are a practical part of daily life and local ecology, so a concise, organized list makes it easier to understand where they run and how they behave.
There are 12 Rivers in Saint Vincent and the Grenadines, ranging from Barrouallie River to Yambou River. For each entry I list Island,Perennial,Source and mouth (short, max 15 words); you’ll find below.
Which rivers on the list are perennial and why does that matter?
The “Perennial” column shows which rivers flow year-round; perennial streams are more reliable for water supply, irrigation and habitat. On the main island you’ll see more perennial rivers fed by higher-elevation springs, while smaller Grenadine streams are often seasonal and may dry in the dry season.
How should I use the table below for travel or basic research?
Use the Island and Source and mouth fields to locate rivers on a map, check Perennial for water availability, and treat the list as a quick reference—verify specifics (access, current conditions) with local maps, guides or recent reports before visiting.
