The Delaware River Basin Commission (DRBC) is a United States government agency created in 1961 by an interstate compact, signed into law by President John F. Kennedy, between four states (Pennsylvania, Delaware, New Jersey, and New York).
The purpose of the Commission is to bring the Delaware River under collective and balanced control, and to ensure fair usage by the states.
To this end, the Commission conducts programs related to water quality protection, water supply allocation and water conservation, regulatory review and permitting, watershed planning, drought management, flood mitigation and loss reduction, and recreational activities (such as fishing).
The DRBC was one of the first government agencies in the United States to address the problem of water pollution.
As of 2021 the commission chair is Delaware Governor John Carney and the Federal Representative is Brigadier General Thomas J.
