View Our 2025 Water Quality Report Card
2025 marked our fifteenth season of data collection and analysis in the waterways flowing throughout the Baltimore region. A snapshot of overall ecological health is shown for each of our 51 monitoring stations here, and a full breakdown of the data is available at BaltimoreWaterWatch.org.
More than one million people live in Baltimore’s Watersheds
For too long, Baltimore’s waterways have been plagued by trash, toxins, sewage, and polluted stormwater.
These problems do more than harm our environment; they threaten the health and well-being of our residents, communities, and local businesses.
Blue Water Baltimore’s mission is to restore the quality of Baltimore’s rivers, streams and Harbor to foster a healthy environment, a strong economy and thriving communities.
Blue Water Baltimore takes a holistic approach to making safe, clean water a reality in Baltimore.
