  abstract = {{L}akes are among the most prevalent and predominant water repositories on the {E}arth's land surface. {A} primary objective of the {S}urface {W}ater and {O}cean {T}opography ({SWOT}) satellite mission is to monitor surface water elevation, area, and storage change in lakes globally. {T}o meet this objective, prior information on lakes, such as locations and benchmark extents, is required to organize {SWOT}'s {K}a{RI}n observations for computing lake storage variation over time. {H}ere, we present the {SWOT} mission {P}rior {L}ake {D}atabase ({PLD}) to fulfill this requirement. {T}his paper emphasizes the development of the "operational {PLD}," which consists of (a) a high-resolution mask encompassing approximately 6 million lakes and reservoirs that meet the minimum size criterion of 1 ha, as defined in {SWOT}'s lake observation science goals, and (b) multiple operational auxiliaries that support the lake mask in generating {SWOT}'s standard lake vector data products. {W}e built the prior lake mask by harmonizing the {UCLA} {C}irca-2015 {G}lobal {L}ake {D}ataset and several state-of-the-art reservoir databases. {O}perational auxiliaries were produced from multi-theme geospatial data to provide essential information for {PLD} functionality, including lake catchments and influence areas, ice phenology, relationship with {SWOT} prior rivers, and spatiotemporal coverage by {SWOT} overpasses. {G}lobally, over three quarters of the prior lakes are smaller than 10 ha. {A}bout 97% of the lakes, constituting half of the global lake area, are fully observed at least once per orbit cycle. {T}he {PLD} will be recursively improved throughout the mission lifetime and serves as a critical framework for organizing, processing, and interpreting {SWOT} observations over lacustrine environments with fundamental significance to lake system science.},
