This DRP is modeled after the 2016 Beaverhead County Drought Resilience Plan authored by Christopher Carparelli for the Beaverhead Conservation District and Watershed Committee. A sincere thank you to those involved in the partnership effort that brought this plan to completion in the name of building community resilience to drought.
