Severn River (Maryland)

Severn River (Maryland). The Severn River is a tidal estuary located in Anne Arundel County, Maryland, on the western shore of the Chesapeake Bay. It serves as a major tributary to the bay and is historically significant as the site of early colonial settlement and the location of the United States Naval Academy. The river's watershed encompasses a mix of residential communities, protected natural areas, and important maritime infrastructure, making it a vital ecological and recreational resource for the region.

Geography and course

The Severn River originates in the upland areas of western Anne Arundel County, near the community of Crownsville. Its non-tidal headwaters flow generally southeastward, feeding into Mill Creek and other tributaries before becoming tidal near Route 178. The main tidal river widens significantly as it passes the United States Naval Academy and the city of Annapolis on its southern bank. It finally empties into the Chesapeake Bay between Tolly Point and Greenbury Point, a peninsula occupied by the Naval Support Activity Annapolis. Major tributaries include Weems Creek, College Creek, and Saltworks Creek, which drain a watershed of approximately .

History

The river is named after the Severn in England, likely by early settlers under the proprietorship of Cecilius Calvert, 2nd Baron Baltimore. The area was originally inhabited by the Algonquian-speaking Piscataway tribe. In 1649, the settlement of "Providence" was established near the river's mouth by Puritan exiles from Virginia Colony, an event considered the founding of Annapolis. The river's strategic importance grew with the establishment of the United States Naval Academy in 1845 on its banks. During the American Civil War, the Union Navy maintained a presence in its waters. The river's shoreline has since transitioned from agricultural and maritime-industrial use to predominantly residential development throughout the 20th century.

Ecology and environment

The Severn River is classified as a shallow, well-mixed tidal estuary with a diverse ecosystem. Its health is challenged by urban runoff, sediment pollution, and nutrient loads contributing to eutrophication and seasonal algae blooms. Key habitats include extensive salt marsh systems, particularly at the Severn River Natural Environment Area, and submerged aquatic vegetation beds crucial for species like the blue crab and striped bass. Conservation efforts are led by organizations such as the Severn River Association and the Maryland Department of Natural Resources. The river is part of the Chesapeake Bay National Estuarine Research Reserve system, and ongoing projects aim to restore oyster reefs and reduce pollutant loads.

Recreation and landmarks

The river is a premier destination for sailing, kayaking, and powerboating, with numerous marinas and public access points like Jonas Green Park. The scenic shoreline is highlighted by historic landmarks including the United States Naval Academy, the Maryland State House, and the William Paca House. The annual Annapolis-to-Newport race and United States Sailboat Show utilize its waters. Natural landmarks include the Black Walnut Point sanctuary and the Sandy Point State Park near its mouth. The Baltimore & Annapolis Trail and the Waterworks Park offer terrestrial recreational opportunities within the watershed.

Crossings and infrastructure

Major crossings of the Severn River include the Severn River Bridge carrying U.S. Route 50/301 and the adjacent, older 1949 bridge now used as a fishing pier. The Naval Academy Bridge carries Maryland Route 450 across the river's upper tidal portion, connecting Annapolis to the Broadneck Peninsula. Other significant spans are the Mills-Parole Bridge and the MD 178 bridge over the headwaters. Critical infrastructure along its banks includes the Annapolis Water Reclamation Facility, the Naval Support Activity Annapolis, and the Annapolis City Dock.
