Definition of Thalweg: 

The thalweg is the deepest ortion of a river or stream that is often referred to as the “low-flow channel.” During the spring and summer when the water is high, you may be able to detect the thalweg as the fast moving “seam” that follows the natural flow line of the stream. During the fall and winter months or a drought, water is concentrated in the thalweg where fish take refuge and try to survive critical low-flow periods.

Ecos concentrates on thalweg and deep pool development in our stream restoration and enhancement projects to ensure our clients can always find hungry, catchable fish throughout the year.
