The DRBC plays a unique role as the agency charged since 1961 with managing the Basin's water resources. Through the DRBC, the states of Delaware, New Jersey, New York, Pennsylvania and the federal government have built an exceptional record of results to improve water quality and provide a sustainable water supply supporting the needs of over 14 million people in four states.
The State of the Basin Report 2025 – the fourth such publication since 2004 – benchmarks conditions and tracks progress toward achieving key DRBC water resource management goals for maintaining an adequate supply of suitable quality water that is equitable, resilient and balances the diverse needs of our region for public water supply, recreation, energy, industry, commerce, agriculture and aquatic life.
This report provides a detailed evaluation – essentially, a focused snapshot – of 36 indicators for watersheds and landscapes, water quantity, climate change, water quality and living resources, and includes a rating and a directional trend for each. A majority of the indicators received a "Good" or "Very Good" rating, while trends are predominantly neutral. Lower ratings or declining trends for some indicators show us where additional study and stewardship are required.
In addition to highlighting the DRBC's work to manage, protect and improve our shared water resources, this report also recognizes the important contributions made by other agencies and organizations who are working together to achieve common goals.
The State of the Basin 2025 report provides a snapshot of 36 different indicators, organized under the categories of:
- Watersheds and Landscapes
- Water Quantity
- Climate Change
- Water Quality
- Living Resources
The report assigns most indicators a staus to provide an approximate gauge of the indicator's current condition and a trend to show how the indicator status appears to be changing. Here's the report's summary table (click to view larger).
