Collecting Stormwater to Help Watersheds

Maryland Sea Grant’s team of watershed restoration specialists works actively to address a persistent threat to water quality -- stormwater runoff.

During big rains, water pools up and washes over hard surfaces like parking lots, roofs, and roads. This runoff picks up nitrogen, phosphorus, and other pollutants, carrying them to nearby streams and rivers and, eventually, the Chesapeake.

Our Extension specialists assist communities throughout the Bay’s watershed to better manage their storm water. Some projects that can help include: 

• Rain gardens: These are deep gardens that soak up the storm water flowing off a roof or down a road. With the right design, rain gardens can also help to decontaminate storm water, retaining pollutants.

See more information from Maryland Sea Grant about rain gardens.

Read “A Garden of Opportunities for Cleansing Urban Storm Runoff,” an article in Chesapeake Quarterly, Maryland Sea Grant’s magazine.

• Rain barrels: Rain barrels catch water flowing off your roof or down the gutter during a big storm. That allows you to store storm water until it’s no longer raining -- once the ground is dry, you can add that water to your lawn or rain garden.
• Plant, plant, plant: Some of the most powerful tools for watershed stewards are native plants. Trees planted  along city streets or in wilderness areas can help to trap the excess nutrients and sediments in rainwater. Native flowers and marsh vegetation planted around ponds can help to keep those water bodies clean, too.

How many homeowners have installed rain gardens? And what would it take for more to do so? A University of Maryland Extension report and survey examines awareness and adoption of four Best Management Practices for controlling stormwater: rain gardens, rain barrels, low fertilizer lawn care, and conservation landscaping.

Habitat Restoration

Our watershed restoration experts also work to help communities and watershed groups restore natural habitats across Maryland. Healthy ecosystems help to trap nutrients and sediments before they reach the Bay. Some of our efforts include:

• Marsh restoration – The Chesapeake’s wetlands are home to birds, fish, and dozens of Bay animals. But they’re also potent tools for keeping water clean. Marsh vegetation and microorganisms filter water streaming toward the estuary.
• Forest buffers – Like marshes, trees planted along a stream can also trap the excess nutrients and sediments in rainwater. To learn more about how trees affect water quality across the watershed, read Can Trees Save the Bay? an issue of Chesapeake Quarterly, Maryland Sea Grant’s magazine.
• Stream restoration – Healthy streams can be a boon for the Bay. Plants and microorganisms living in and around small waterways capture excess nutrients. But, because of development and other factors, many local streams around Maryland have lost much of their capacity to do just that. We support efforts to restore these beneficial functions to the state’s small waterways.

Benefits of Watershed Restoration

Cleaner water provides benefits at the local level and Baywide:

• Drinking water: Various pollutants may, at times, build up in many of the freshwater streams and rivers that supply drinking water to towns across the state. Reducing the pollutants, such as heavy metals, and excess nutrients, which cause harmful blooms of algae, that enter small waterways can ensure the sustainability of your town’s water supply.
• Habitat: Clean waterways provide living space for diverse wildlife, including birds, frogs, fish, and countless plant species.
• Recreation: Vibrant streams, rivers, lakes, and ponds are excellent venues for fishing, hiking, biking, and many more outdoor activities.
