Summary 
The Land Capability Potential Index (LCPI) is a relatively coarse-scale index intended to delineate broad land capability classes for approximately 811 miles of the Missouri River flood plain in South Dakota, Nebraska, Iowa, Kansas, and Missouri (river miles 811-0). The LCPI provides a systematic index of relative wetness potential and soil moisture-retention potential of the valley-bottom lands by combining the interactions among land-surface elevations, water-surface elevations, and the inherent moisture-retention capability of flood plain soils. These data should be considered indicative of general conditions rather than relevant to contemporary, site-specific conditions.
Description 
The Land Capacity Potential Index (LCPI) was created by integrating a series of eight modeled water-surface elevations, land-surface elevations, and soil permeability datasets for the Lower Missouri River Valley. The LCPI estimates relative wetness based on intersecting a series of eight modeled water-surface elevations with a high-resolution land-surface elevation model. These intersections spatially illustrate areas of the valley bottom which can potentially be inundated by surface water at various elevations. These potential inundation areas were then integrated with the soil drainage classes assigned to soils units in the digital Soil Survey Geographic Database to create a systematic index of wetness potential and moisture-retention capability of Missouri River valley-bottom lands.
