Map 2: Farmland Soils Classification
This map displays types of farmland, as defined by the Natural Resources Conservation Service, in the Middle Mississippi River floodplain. Farmland types are classified based on their chemical and physical properties and their suitability for farming. Prime farmland contains the highest quality and most agriculturally productive soils. There are also conditional prime farmland classifications based drainage or protection from flooding. Farmland of statewide importance is slightly less productive than prime farmland, but still provides high quality soil for crop production.
Map 3: Flooding Frequency
This map displays areas in the reach based upon how often flooding occurs as determined by the Natural Resources Conservation Service.

Map 4: Hydric Soils Classification
This map displays hydric soils as defined by the Natural Resources Conservation Service. A hydric soil is a soil that formed under conditions of saturation, flooding or ponding long enough during the growing season to develop anaerobic conditions in the upper part.
Note: Partially hydric soils exhibit some, but not all of the characteristics of hydric soil.
Map 5:1800, 1890 & 2000 Land Cover
This map displays three snapshots of the land cover in 1800, 1890 and 2000 providing a comparative visual of how land cover has changed in the corridor since 1800.
Map 6: Remnant Vegetation
This map displays native vegetation that remains mostly intact and undisturbed since European settlement or those areas which can easily be retuned to pre-European settlement conditions.
