Bay Grades Highest

Chesapeake Bay earns its best report card in 40 years: C

The Chesapeake Bay just earned its best report card in 40 years: A respectable — if not quite honor roll-worthy — C+.

Why it matters: It's encouraging progress for America's largest estuary — a playground for boaters, a livelihood for watermen and a critical habitat for wildlife — after decades of efforts to clean up pollution and restore the Bay.

Driving the news: Eight of the Bay's 15 regions are showing long-term improvements in environmental health, up from six in last year's report card from the University of Maryland Center for Environmental Science.

The Lower Bay, near Virginia Beach, earned a record B+, while Maryland's western shoreline south of Annapolis lagged with a D-.

Closer to home, the Potomac River earned a C-, the same grade as last year, though its numerical score rose three points.

What's working: Decades of upgrades to wastewater treatment plants and efforts to curb fertilizer and stormwater runoff have reduced pollution, along with investments in restoring oyster reefs — nature's water filters.

Scientists are also seeing improvements in underwater grasses and oxygen levels that sustain aquatic life.

The big picture: The report comes at a time of uncertainty for federal restoration efforts.

The Trump administration last month revoked a 2009 Obama-era order that expanded federal coordination around Chesapeake Bay restoration.
Trump's replacement order emphasizes "on-the-ground" pollution reduction projects, such as planting trees to curb fertilizer runoff, but leaves questions about how federal funding, staffing and oversight will support long-term restoration efforts.

What they're saying: Virginia Natural and Historic Resources Secretary David Bulova called the gains especially remarkable amid population growth, climate change and invasive species like blue catfish.

"I'm amazed that we make progress at all," he said at Tuesday's announcement. "It really does speak to the incredible job that we are doing to push the ball forward."
