Rip rap removed and replaced with a sill and restored marsh, enhancing habitat while reducing nutrient impact.

A National Estuary Program partnership · Est. 1996
From Assawoman to Chincoteague, we monitor the water, restore the habitat and bring the community into the work — so Maryland's coastal bays are healthier for the people and wildlife that depend on them.

Largest of the five watersheds
The largest watershed, shared with Virginia
Chincoteague Bay watershed is the largest of the five watersheds. It includes land south of Langmaid Road to the Virginia border and into Virginia; half of the drainage area is in Accomack County, Virginia, including the town of Chincoteague. The watershed contains extensive marshes, farms and forest, with close to half of it forested. Ten of twelve wetlands of special state concern are here — sites of rare, threatened and endangered species — and the bay's importance to migrating waterfowl is noted internationally.
Impact right now
Living shorelines, reopened fish passage, rebuilt islands and protected headwaters — active and completed projects across the watershed.

Our strategic priorities
They come straight from the Comprehensive Conservation and Management Plan — the shared plan behind the partnership.
Priority 1
Water quality is the single critical factor in protecting the Coastal Bays — measured, tracked and improved year after year.
See the work
Priority 2
From horseshoe crabs to terns and terrapins, our surveys and habitat work keep the bays' species counted, understood and protected.
See the work
Priority 3
Nature-based solutions — living shorelines, restored marsh and protected islands — that hold up as seas rise and storms intensify.
See the work
Priority 4
Students, educators, volunteers, businesses and agencies working the same plan — because no single organization can restore a watershed.

The data
Long-term monitoring feeds the Coastal Bays Report Card and the deeper State of the Bays assessment. The 2021 report card ranks the ecosystem health of each bay against the others.
1 = healthiest of the five bays, 5 = most stressed.
| Bay | Rank | Watershed |
|---|---|---|
| Sinepuxent Bay | 1 | Smallest of the five subwatersheds |
| Chincoteague Bay | 2 | Largest of the five watersheds |
| Isle of Wight Bay | 3 | Second largest of the five bays |
| Assawoman Bay | 4 | Drains parts of Worcester and Sussex counties |
| Newport Bay | 5 | Most stressed ranking in the 2021 report card |

Stories & news

Coverage rose steadily from 1986 to 2001, then levelled off. The recent downward trend is the number our monitoring crews are watching most closely.

A hardened shoreline protects one property and costs the bay a habitat. Here's what replaced it, and what came back.

Late spring evenings, a measured transect and a clipboard. This is what the spawning survey looks like from the beach.
Get involved
An hour on a Saturday, a dock, a boat, a classroom or a company — every one of these makes measurable difference in the bays.
Individuals
Raise a cage of juvenile oysters from your dock and return them for planting on restoration reefs.
Individuals
Count spawning crabs on index beaches using the standard protocol, and right stranded animals.
Families
Remove debris and derelict gear from shorelines and the water — the easiest first way to help.
Individuals
Support the monitoring network with sample collection and instrument readings on a set schedule.
Support the bays
Your contribution goes toward protecting the watershed, its habitat and its wildlife — monitoring crews on the water, marsh replanted at eroding shorelines, and students in the field. The Maryland Coastal Bays Program Foundation is a 501(c)(3) nonprofit; all donations are tax deductible.
