Historic wetland footprints produced by combining National Wetland Inventory (NWI, 2009 updated), NRCS hydric soils data, and contemporary field surveys. These historic footprints provide the basis for restoration implementation within the Rainwater Basin Wetland Complex. This data was revised in 2016, succeeding the 2004 version. The 2016 revisions included eliminating historic wetland survey data, replacing NWI with the 2009 updated data, and inclusion of Olbut soils as a hydric soil class.
