The Indicator Redesign Taskforce was assembled to provide a vision for the Chesapeake Bay Program indicators and the manner in which they are communicated. In doing so, the Indicator Redesign Taskforce is initiating and steering the necessary changes through the Monitoring and Analysis Subcommittee. This document describes the goals, approach and methods used to redesign the ecological indicators and outlines the communication strategy used to convey these changes to the public.

Assessment of sewage and septic derived nitrogen in the Choptank and Patuxent Rivers

Jones AB, Dennison WC and Pantus F ·
1 December 2003

An assessment of nitrogen sources to the Choptank and Patuxent River (including Island Creek), was conducted during the summer of 2003. Results demonstrated that both rivers were compromised with sewage derived nutrients. An Ecosystem Health Index for defined reporting regions was calculated from a variety of ecosystem heath parameters and then converted to a report card grade from A+ to D- and F for fail (Table 1).

15 September 1999

Scientists from the University of Maryland Center for Environmental Science have evaluated the scientific understanding and uncertainty related to five issues regarding the environmental effects of placement of dredged sediments at Site 104, at the head of the deep, natural channel of the Chesapeake Bay. This assessment was based on reviews of relevant studies and impact statements as well as on the scientists’ extensive knowledge and experience concerning the Chesapeake Bay ecosystem.
