Guidance for Legacy Data and Legacy Systems

The guidance provided in this document is designed to address a critical barrier to understanding and effectively managing surface and groundwater (SWGW) interactions in Texas: legacy data and legacy systems. Data held in legacy systems are difficult to find, access, and integrate with other data, and because of this, these data are rarely used in decision-making processes. Improving the findability and accessibility of legacy data is a foundational step in improving water management decisions about SWGW interactions in Texas. However, this same guidance can be applied to address challenges with legacy data and systems for a variety of other applications.
