Lakes and reservoirs have a profound influence on ecosystem functions, local streamflow levels, and the movement of water across landscapes. But water managers often are in the dark when it comes to subsurface topography, which affects the ecology, volume, temperature, and rate of evaporation of a waterbody, as well as inflows and outflows.
