Welcome to the Interagency Ecological Program (IEP). The IEP is a consortium of state and federal agencies that have been conducting cooperative ecological investigations since the 1970s (for more on IEP’s history, click here).

The IEP’s mission is to provide and integrate relevant and timely ecological information for management of the Bay-Delta ecosystem and the water that flows through it. This is accomplished through collaborative and scientifically sound monitoring, research, modeling, and synthesis efforts for various aspects of the aquatic ecosystem.
