Chesapeake Bay - Report Card:

Chesapeake Bay scored 38%, a D+, in overall health for 2011. This report card provides a transparent, timely, and geographically detailed annual assessment of 2011 Chesapeake Bay health. It rates 15 reporting regions of the Bay using six indicators that are combined into a single overarching index of health. This website enables you to explore the report card via the 15 Bay regions, by the indicators and indices, and as an overview of 2011 Bay health.

A report card is released each year providing an assessment of the previous year's health. Health is defined as progress of the six indicators towards established scientifically derived ecological thresholds or goals. A low score therefore means that the region rarely meets the ecological threshold levels. A high score means that the region often meets the threshold levels.
