The purpose of the Cooperative Watershed Management Program Reauthorization Act of 2026 is to continue and enhance a program that supports collaborative efforts to manage and protect watersheds across the United States. This program aims to address issues related to water resources, particularly in the face of challenges like drought and wildfires. Key provisions of the Act include several important updates to the existing law. First, it expands the definition of eligible participants to include Indian tribes, recognizing their role and rights in watershed management.
