Indicators Workgroup

Scope and Purpose

The Indicators Workgroup promotes the development of indicators that effectively communicate progress in the restoration of living resources, water quality and habitat in the Chesapeake Bay and its watershed.  The workgroup provides guidance to Scientific and Technical Analysis and Reporting Team and the other teams and workgroups that have the responsibility for the selection of appropriate metrics and the analysis and interpretation of data for individual indicators.
