Tabular data that represent the proportion of area classified as waterfowl habitat for each of three series of habitat maps were developed based on water distributed across the Central Valley and Suisun Marsh in California during October-March of 2014-15 through 2017-18. We used open water data (version without cloud-filling) publicly available on Point Blue Conservation's California Water Tracker web site and which Point Blue derived at 16-18 day intervals from mosaics of Landsat 8 imagery for the region including the Central Valley and Suisun Marsh. Each record in the data set represents a mosaic within a specific range of dates of imagery that together bound the Central Valley and Suisun Marsh spatial extent. In a geographic information system (GIS), we used each mosaic to calculate the proportion of potential waterfowl habitat for each range of dates (yyyymmdd to yyyymmdd format) indicated in column one. The proportion was calculated for each of three maps, indicated in column 2-4 headings, that we developed using the open water data. As one measure to compare performance of the three maps, we summarized the mean and range of the proportion of area that was classified as habitat across all mosaics used; generally, the less area classified as habitat, while also accounting for actual locations of waterfowl (for example with telemetry data) the better.
