Save the Bay™, and keep it saved, as defined by reaching a 70 on CBF's Health Index. The Chesapeake Bay Foundation's (CBF) mission, simply stated, is to Save the Bay and keep it saved. We define a Saved Bay as having a score of 70 (out of 100) on CBF's State of the Bay health index. Thanks largely to a dramatic reduction in the amount of pollution entering the system, at 70, the Chesapeake Bay and its tributary rivers will be highly productive and in good health as measured by established water-quality standards. The result will be clear water, free of impacts from toxic contaminants, and healthy oxygen levels, able to support living resources in all parts of the Bay.
