This data layer represents the Stream Power Index (SPI) derived from high-resolution Lidar topographic data for Minnesota. It was modeled by Iowa State University using hydrologically-enforced 2m digital elevation model (DEM) of each HUC 12 level minor watershed. SPI provides a measure of the erosive power of flowing water calculated based upon slope and contributing area.
