State of the River Report Card
We regularly provide a progress update on the Anacostia River in part to create accountability for decision makers entrusted with the health of the river. This report card is your guide to how well our communities, environmental groups, and governments are meeting the goal of a fishable and swimmable Anacostia River, per the terms of the Clean Water Act. Provided here is a summary of the scientific data we have analyzed so that citizens and public officials can better understand the current state of the Anacostia River.
Our 2020 Report Card receives a passing grade of D, the second passing grade in 3 years showing that the river is improving towards swimmable and fishable.
- The score for the Anacostia River increased 12 percentage points from 51% last year to 63%, the highest score to date.
- After the historic rainfall in 2018 wiped the river's submerged aquatic vegetation (SAV), these underwater grasses came back with a vengeance covering over 96 acres!
- Many parameters had passing grades this year, including Fecal Bacteria, Chlorophyll a, SAV, Stormwater Runoff Volume, and Trash Reduction.
- Dissolved Oxygen continues to mysteriously degrade.
The mission of the Anacostia Watershed Society is to protect and restore the Anacostia River and its watershed communities by cleaning the water, recovering the shores, and honoring the heritage. We believe that by working together with businesses, governments, faith-based organizations, and youth we can create sustainable solutions that improve our communities, empower our residents, and create economic prosperity that will result in a clean river. We want to change the way people think about the Anacostia and make the river a destination.
Challenges to Overcome
The most important parameters for a swimmable and fishable Anacostia River are fecal bacteria, toxics, trash, and uncontrolled stormwater. High fecal bacteria levels indicate that the water contains many types of disease-causing viruses, bacteria, and protozoa that can be hazardous to human health. We don't yet know the specific health risks associated with occasional exposure to the toxics (heavy metals, pesticides, and other chemicals) in the sediment in the river, but we do know that those contaminants are having a negative impact on fish populations and that removing or treating toxic sediment will be necessary for the river to sustain healthy fish safe for human consumption. Stormwater runoff is a major issue because runoff from impervious surfaces (e.g., roads, parking lots, driveways, roofs) brings numerous pollutants to streams and generates torrential stream flow, which causes streambank erosion and makes the water cloudy and inundates the river with sediment. The runoff also carries fecal matter, trash, and other pollutants to the river.
Data Sources and Disclaimers
- Data set: All available, professionally collected data was used. The data sets include those collected by DC government, Maryland Department of Natural Resources, United States Geological Survey, and the Anacostia Watershed Society.
- The data was compared with thresholds developed by Mid-Atlantic Tributary Assessment Coalition (MTAC) who created EcoCheck protocols - Sampling and data analysis protocols for Mid-Atlantic tidal tributary indicators.
- For the 2020 State of the Anacostia River Report, the data used for Remediation Indicator evaluations and Water Quality Indicator analysis were done for 2019.
- For trend analysis, data sets from 1984 to 2018 were used depending on the parameter and the section of the river.
- Note that no Report Card was issued in 2013 and that the one issued prior to that was dated 2011 (for the year representing most of the available data, rather than the year it was issued, 2012.)
