Overview
As part of the U.S. Department of Agriculture's (USDA) use of digital mapping technology to increase efficiency, the Farm Service Agency (FSA) and the Natural Resources Conservation Service (NRCS) use point symbols to identify wetland determination locations on FSA maps. NRCS has the ability to make wetland determinations based on landowners' requests. FSA and NRCS use point symbols, known as wetland determination identifiers, to show the approximate location of NRCS wetlands on digital maps making those areas more easily identifiable for producers.
The maps are used primarily for producer information when making crop acreage reports, changing field boundaries or requesting a map of their land from FSA.
Wetland Point Symbols
Red, yellow and green symbols represent different categories of wetland determinations and a legend provides an explanation of the various levels of use that are allowed on these wetlands.
Red octagons represent "Restricted Use" determinations; upside-down yellow triangles represent "Limited Restrictions" determinations and; green circles represent 'Exempt from Conservation Compliance Provisions" determinations.
- Restricted Use = W (Wetland); CW, CW+YR (Converted Wetland + Year); AW/W (Artificial Wetland/Wetland); GFW, GFW+YR (Good Faith Wetland + Year); RSW, RSW+YR (Restored Wetland + Year); RPW (Replacement Wetland).
- Limited Restrictions = FW (Farmed Wetland); FWP (Farmed Wetland Pasture); CWNA (Converted Wetland, Non-ag Use); AW/FW (Artificial Wetland/Farmed Wetland); CWTE (Converted Wetland Technical Error); TP (Third Party Conversion); WX (Manipulated Wetland) MW; CMW (Minimal Effect Wetlands); MIW, MWM (Mitigation Wetlands); NI (Not Inventoried); OW (Other Waters); Easement.
- Exempt from Conservation Compliance Provisions = PC (Prior Converted); NW (Non Wetland); PC/NW (Prior Converted/Non Wetland); CC (Commenced Conversion); NW/NAD (Non Wetland, National Appeal Decision); AW (Artificial Wetland).
The wetland determination identifiers do not represent the size, shape, exact location or exact category of wetland determination, and the maps are not used for wetland conservation compliance.. USDA participants remain responsible for self-certifying compliance with USDA wetland conservation provisions.
For More Information
The maps with the identifiers are not the official USDA wetland determination maps. Producers who have questions about the size, shape, exact location or exact category of the determination should refer to the determination information previously provided to them by NRCS on form CPA-026e and attached maps, or contact their local NRCS office. Both FSA and NRCS have the USDA wetland determination maps available for landowners and operators. Copies of these original maps have previously been provided to all producers. Producers may request a replacement copy through their local FSA or NRCS office if they no longer have the original.
