The purpose of the WSQT v2 is to calculate functional lift and loss associated with reach- scale stream restoration and impact activities.

A main goal of the WSQT is to produce objective, verifiable, and repeatable results by consolidating well-defined procedures for quantitative measures of structural or compositional attributes of a stream and its underlying processes.
