Evapotranspiration Data Act: Improving Water Management and Drought Resilience

This Act authorizes the Secretary of the Interior to develop and provide accurate data on evapotranspiration (ET), which measures water lost from the land to the atmosphere. Better data will help farmers and water managers make more informed decisions, crucial for protecting farm finances during drought and promoting sustainable water use. Citizens benefit from improved regional water resource management, directly impacting the stability of water supplies.
Key points
Establishment of a program to evaluate, analyze, and provide accurate satellite-based ET data across large landscapes, including agricultural and urban areas.
Support for water users and decision-makers to better manage resources, protect the financial viability of farm operations during drought, and enhance conservation efforts.
Creation of an Advisory Committee composed of experts, farmers, and Tribal representatives to ensure the data is useful and reflects the best available science.
Data privacy requirement: ET data must be aggregated or de-identified to protect personally identifiable information and entity-specific details.
