Location Lower Missouri River Floodplain from Sioux City, IA to St. Louis, MO

Summary

This wetland monitoring and assessment study applied and tested assessment tools (e.g., criteria/metrics, protocols) created in Phase I, provided an unbiased estimate of the current condition of floodplain wetlands in the Lower Missouri River study area, and assessed the veracity of reference conditions determined in Phase I. Goals were accomplished by gathering and assessing water quality, floristic, macroinvertebrate, and landscape data from a population of ca. 40 wetlands selected by an EMAP probability-approach.

The shapefiles we used to select study sites within the lower Missouri River floodplain are available by clicking the file names below. This will download a zipped file containing multiple files.

RASTER files

Floodplain – floodplain_dtf_max16m_morv Contains a 2.4 GB layer. Email us if you'd like this.
“Depth To Flood” (DTF) map (16m) for the Missouri River study reach. This is the most recent version, computed in 2007 using the fully developed FLDPLN model. This will differ from the one used at the beginning and throughout much of the project, which was computed using an early version of the FLDPLN model (pre-spillover flooding, only backfill).

NLCDnlcd92_reclass_huc8_mobuffer
Reclassified 1992 NLCD, clipped to the HUC-8 buffer area. Reference land cover classes have been coded to 1, and all others to 0 (background is 255, which has been assigned to the ‘NoData’ value).

VECTOR files

Extent polygon for floodplain_dtf_max16m_morv.

HUC8 watersheds – huc8_mobuffer
HUC-8’s that intersect the Missouri River floodplain in the study area.

NWI wetlandswetland_morv
NWI floodplain wetlands with area > 10 acres and located in the Missouri River floodplain study area.

Public land – clipped to the floodplain

  • parks_huc8_mobuffer – A parks layer (1 of 2) used to identify the location of public lands in the HUC-8 study area. Lands and boundaries in this layer differed slightly from the other layer, so both were used.
  • parks_dtl_huc8_mobuffer – A parks layer (2 of 2) used to identify the location of public lands in the HUC-8 study area. Lands and boundaries in this layer differed slightly from the other layer, so both were used.

Hydric soil classhydric_soils_morv
NRCS SSURGO polygons identified as hydric using NRCS hydric criteria 2-4. This file is composed of merged county-level files, which accounts for its odd shape. Data for Harrison County in Iowa were not available at the time these data were assembled for the project.
