Collaborative Science and Adaptive Management Program


The Collaborative Science and Adaptive Management Program (CSAMP) was launched following a decision by the United States District Court for the Eastern District of California on April 9, 2013. The decision entitled “Memorandum Decision and Order regarding Motion to Extend Remand Schedule” (Court Order) was issued in response to a motion to extend the court-ordered remand schedule for completing revisions to salmonid and Delta Smelt Biological Opinions (BiOps).

The Court Order allowed the parties making the motion (i.e., U.S. Bureau of Reclamation, U.S. Fish and Wildlife Service, National Marine Fisheries Service, and the California Department of Water Resources) additional time for the development of a proposed robust science and adaptive management program, with collaboration of the scientists and experts from the Public Water Agencies (‘PWAs’) and the NGO community with the intent to inform the management actions incorporated into the existing BiOps (and Reasonable and Prudent Alternatives) and consideration of alternative management actions.

In April 2013, the Court granted a one-year extension of time. The parties filed an annual progress report in February 2014, and the Court granted a second one-year extension in March 2014. The parties prepared a second annual progress report in February 2015, requesting a third one-year extension. In the intervening period, however, the Ninth Circuit reversed the Court’s decision with respect to the smelt and salmonid BiOps and issued a final judgment, thereby ending the Court Order (additional annual progress reports).

In the absence of the Court Order, in 2015 all parties agreed to continue the CSAMP to promote the collaborative development of scientific information to inform sound decision-making in the future.


The CSAMP is structured (Figure 1) as a four-tiered organization comprised of:

  1. CSAMP Policy Group consisting of agency directors and top-level executives from the entities that created CSAMP;
  2. Collaborative Adaptive Management Team (CAMT) made up of managers and staff scientists that serve at the direction of the Policy Group;
  3. Scoping Teams created on an as-needed basis to scope specific science studies; and
  4. Investigators contracted to conduct studies.
