A downstream “V” is formed in deep water when the current is channelled between or past two obstacles. It is often easy to see as it is a darker solid section of current, flanked by two strong eddie lines or white shoulders. A downstream “V” can be created by a number of different river features including rocks, drops and angled holes or waves.
The downstream “V” is often an indicator of a potential good line through a rapid. It is generally a place where water continues to flow downstream.
In white water kayaking there are few absolutes so even if you see a downstream “V” look at all the variables to make sure that it is the place you want to go.
