Gallatin Drought and Deluge Adaptive Management Plan
The purpose of the Gallatin Drought and Deluge Adaptive Management Plan (DDAMP) is to coordinate drought communication and voluntary conservation efforts across the entire Gallatin Watershed, and to identify long-term mitigation and response actions that build resilience and effective management during times of drought and deluge.
The Challenge: The Gallatin Watershed is experiencing rapid change. Population growth, changing land use practices, climate impacts, and increasing demands on water resources call for greater coordination to inform, respond to, and mitigate the impacts of drought and deluge. Prior to this effort, the Gallatin Watershed has lacked coordinated water-event response strategies and communications, as well as a strategic approach to long-term water conservation and watershed resilience projects.
The Drought and Deluge Adaptive Management Plan (DDAMP)
The Solution: The Gallatin Drought and Deluge Adaptive Management Plan (DDAMP) is a collaborative, stakeholder-driven framework developed to improve how communities, water users, agencies and watershed organizations prepare for, respond to, and adapt to drought and deluge conditions across the Gallatin Watershed.
The DDAMP establishes voluntary drought and deluge response frameworks that connect monitoring information to recommended management actions. The DDAMP does not create new regulatory authority or mandatory requirements. Instead, it complements existing local, regional, and state plans by providing a voluntary watershed-scale framework for coordination, communication, planning and decision support.
The Draft DDAMP is currently available for review. Please use the form linked below to submit any feedback, edits, or comments by November 13, 2026 to be incorporated into the final plan.
Stakeholder engagement has been central to the development of the DDAMP, with the Gallatin Water Collaborative playing a key role in convening partners and fostering coordination. Through facilitated meetings, surveys, and discussions, stakeholders have contributed input on monitoring indicators, thresholds, communication needs, and implementation strategies; ensuring the plan reflects both technical expertise and local knowledge. Meeting notes and resources that helped to shape the plan can be found below.
