From 2022-2023, the COAST Card project held a series of listening sessions to stimulate community engagement throughout the Potomac Watershed. This poster summarizes the results of the activities at those listening sessions.

The first-ever Potomac River and Watershed Report Card was released in tandem with the 2022 Chesapeake Bay and Watershed Report Card this year. Every year, the Chesapeake Bay and Watershed are graded on a variety of ecological, social, and economic indicators. For 2022, the COAST Card Project took a closer look at the Potomac Watershed, a sub-watershed of the Chesapeake, to help inform decision-making in more focused areas throughout the watershed.

Many coastal ecosystems suffer from eutrophication, algal blooms, and dead zones due to excessive anthropogenic inputs of nitrogen (N) and phosphorus (P). This has led to regional restoration efforts that focus on managing watershed loads of N and P. In Chesapeake Bay, the largest estuary in the United States, dual nutrient reductions of N and P have been pursued since the 1980s.

The Potomac Tributary Report summarizes change over time in a suite of monitored tidal water quality parameters and associated potential drivers of those trends for the time period 1985 – 2018, and provides a brief description of the current state of knowledge explaining these observed changes.

This report card was produced in December 2015 by The University of Maryland Center for Environmental Science and represents a joint effort of graduate students and faculty in the Marine Estuarine Environmental Sciences program at the Appalachian Laboratory in Frostburg and the Integration and Application Network. The report card provides an assessment of stream health in the Upper Potomac Headwaters region upstream of Harpers Ferry, West Virginia.

Climate change will affect Maryland in a variety of ways. More obvious impacts could include an increased risk for extreme events such as drought, storms, flooding, and forest fires; more heat-related stress; the spread of existing or new vector-born disease; and increased erosion and inundation of low-lying areas along the State’s shoreline and coast. Adaptation, together with mitigation, is necessary to address climate change.

Maryland citizens are blessed with an abundant supply of water. However, many water systems are already stressed during droughts, and infrastructure damage and water contamination occurs during floods. Future population growth will combine with increasingly variable weather patterns to place more communities at risk of property damage, regulatory liabilities and uncertain access to drinking water.

Risk management is critical in any restoration project. Risks include those associated with climate patterns, such as more intense storms, as well as those associated with land use change, site selection, and design. Addressing these risks in conjunction with ongoing restoration efforts will prepare communities for greater variability and may result in cost savings and reduced risk. Best Management Practices (BMPs) should be sited and designed with climate change impacts in mind.

Maryland’s extensive aquatic ecosystems range from freshwater swamps and bogs to freshwater rivers and marshes to coastal bays and salt marshes. These ecosystems are influenced by precipitation, temperature, tropical storms, and human activity. Human development and pollution have degraded their natural resilience, leaving them more vulnerable to climate change and extreme events.
