Technical Abstract: Playas are ephemeral wetlands on the semi-arid U.S. Southern High Plains that serve as runoff catchment basins and are thought to be focal points of Ogallala aquifer recharge. Sediments in playas alter biodiversity and hydroperiods. The purpose of this study was to evaluate the effects of outerbasin vegetation on post-cultural sediment deposition in three pairs of cropland/native grassland playas. Sediment volume was directly related to watershed land use with more accumulated sediment and decreased playa depth in cropped playas than in grassland playas.
