Yes. In some river study authorizations Congress has required the study agency to work with state and local governments and the public to develop a CRMP in concert with the study process to assist in determination of the river’s suitability. Such pre-designation CRMPs have, in some cases, been adopted in the legislation adding the river to the National Wild & Scenic Rivers System. In cases where Congress has not authorized a pre-designation CRMP, agencies have taken the initiative to develop elements of the CRMP in the study report (pre-designation).
