Restoration of Lake Marion Set to Enhance the Health of the Severn River Watershed

Annapolis, Maryland-This spring, Lake Marion in Severn, Maryland will undergo
large-scale restoration to enhance the lake’s habitat and restore its capacity to store and
treat stormwater. After years of planning by nearby residents, partners from the
Provinces Civic Association, Arundel Rivers Federation (Arundel Rivers), and Severn
River Association (SRA) will soon break ground on the $3.8 M lake restoration project.
Lake Marion is at the very beginning, or headwaters, of the Severn River and was
originally a natural stream that was converted into a stormwater management feature in
the 1970’s designed to collect potentially harmful stormwater runoff from surrounding
communities. As water flows through developed areas, it picks up pollutants such as
sediment, nitrogen, and phosphorus and sends them downstream where they can
threaten the health of everything from underwater grasses to fish and oysters in the
Chesapeake Bay and its tributaries. Stormwater management practices, like Lake
Marion, collect that polluted water before it enters tidal waters, in this case, the Severn
River. After filtering stormwater for more than half a century, the lake has filled with
sediment and debris, causing it to overflow sending polluted stormwater into a
headwater tributary of the Severn River and eventually into the Chesapeake Bay.

“Lake Marion, like so many of our older stormwater ponds, has lost its ability to protect
our rivers and only a large-scale restoration project can bring it back better than it was
before,” said Matt Johnston, Executive Director of Arundel Rivers. “Restoration at this
scale requires teamwork through robust partnerships of funders, community leaders,
and watershed organizations. It’s only when we work together that we can truly protect
our communities and the Chesapeake Bay. So Arundel Rivers is thrilled to be partnering
with our colleagues at Severn River Association and the Provinces Civic Association to
restore Lake Marion.”

The project will use an innovative, comprehensive approach to restore the lake’s
effectiveness. Several feet of accumulated sediment from the bottom of the lake will be
excavated to restore the lake’s stormwater storage capacity. Additionally, an existing
concrete spillway, or outfall channel, leading to Severn Run will be removed and
transformed into a series of pools. A large wetland will be created in a portion of the
lake to provide new habitat for native plants and creatures.

“Severn River Association is incredibly excited about this project to breathe fresh life
into Lake Marion.” Said Ben Fertig, Restoration Manager at Severn River Association.
“This is a fabulous opportunity to improve water quality, reduce sediment and nutrient
pollution, and to deliver cooler, cleaner water to the Severn Run Natural Area. Improving
stormwater management and wildlife habitat will have measurable results as we work
together to restore and protect the Severn River and its creeks and tributaries for all our
“The Provinces Civic Association, Inc. (PCA) is very pleased that our efforts to promote
a Lake Marion Stormwater Restoration project are finally coming to fruition.” Says PCA
President, Cynthia Williams. “After many years of effort, the PCA has at last secured the
necessary funding required to carry out modifications to our stormwater system. When
completed it will benefit both the Severn Run and our own community park. We thank
our financial sponsors and all those community residents who have supported this

Funding for the project is provided by the Maryland Department of Natural Resources,
Maryland Legislative Bond Initiative, Local Development Council, Anne Arundel County
Watershed Protection and Restoration, Provinces Civic Association and private
community donations. Design for this project was created by the engineers at Baylands
Consultants and Designers, Inc. and Pay Dirt, LLC will serve as the construction
contractor. Construction on Lake Marion will begin this spring and is projected to
continue through spring 2025. For more information please visit the project website at
