On January 5, 2017, the Chesapeake Bay Foundation (CBF) released its annual “State of the Bay Report,” for conditions in 2016, the Foundation’s first such report since 2014. For 2016, CBF gave the Bay an overall index score of 34, which the organization rates as a “C-.”
In each report, CBF rates 13 biological and chemical measurements from 0 to 100, with higher scores indicating better conditions and 100 intended to represent conditions as described by European settler Captain John Smith in the early 1600s. The report then averages the scores to give an overall Bay score.
The overall score of 34 for 2016 was a two-point increase over the 2014 score and a six-point increase since 2008. The overall increase in 2016 was due to increased scores for nine of the 13 indicators, including an increase the Blue Crab populations score from 45 to 55 and an increase in the dissolved oxygen score from 19 to 25. Despite the increases, however, the ratings for the following measures continue to be considered by CBF as poor (getting a “grade” of D or below): nitrogen, oysters, phosphorus, resource lands, shad, submerged aquatic vegetation (“underwater grasses”), toxics, and water clarity. The scores for Blue Crabs, forested buffers, Rockfish (Striped Bass), and wetlands were all considered fair or better.
The table below compares scores for 2016 and several previous five reports. The CBF report (see p. 9) asserts that the 2016 overall average score of 34 represents an “improving” but “far from saved” Bay; CBF’s “About the State of the Bay Report” Web page characterizes a score of 70 as “saved,” and the organization sets that score as an “achievable” goal by 2050.
