Technical Report for the Delaware Estuary & Basin

The Partnership for the Delaware Estuary, in conjunction with other environmental practitioners in Delaware, New Jersey and Pennsylvania, recently released the 2022 Technical Report for the Estuary and Basin (TREB) to update environmental indicators discussed in the 2017 TREB. The purpose of this update is to provide readers with insight into the status and trends of select natural resources in the Delaware Estuary’s Watershed, home to approximately 9 million people.

The Partnership worked closely with the Delaware River Basin Commission, state and federal agencies, universities, and its 21-member Science and Technical Advisory Committee to share data and provide at least 5 years’ worth of updates for more than 70 key environmental indicators throughout the Delaware Estuary. Indicators were carefully chosen based on the data available and its ability to help readers understand current conditions and future needs.

According to the report, the state of the Delaware Estuary is “fair.” Some environmental conditions appear to be improving, while others appear to be worsening. Similarly to the 2017 assessment, data suggest that the current health of the Delaware Estuary and River Basin is and remains unchanged from the 2017 Report. This and other prior Estuary Reports can be viewed below.
