Surface Waters and Wetlands Inventory
• What is SWI o Often referred to as version 2.0 of the National Wetlands Inventory (NWI)
o Provides more inclusive geospatial data of all wetlands and surface water
features.
o SWI is a derived dataset that depicts all surface water and wetland features in a single feature class
• Retains the wetland and deepwater polygons from NWI • Reintroduces linear wetland features orphaned from original NWI hardcopy
maps by converting them to narrow polygonal features • Supplements the dataset with buffered hydrographic linear data that were
missed by NWI mapping or to complete segmented connections o Applies the Cowardin et al. (1979) system to provide consistent
ecological descriptors o E.g. PEM1C, PFO2/4Bg, PUBHx, E2EM1P

SWI polygons
*SWI includes 207 freshwater emergent, 173 forested/shrub, 122 freshwater pond and 1,039 riverine linear segments from original NWI mapping efforts. Some of these segments have been merged with hydrography segments to create a uniform wetland network.

Surface Waters and Wetlands Inventory
• Why SWI o It stems from the need to represent all surface waters and wetlands as polygons
in a geospatial dataset to facilitate accurate area calculations and provide consistent, standardized ecological classification to allow for adaptive management, geospatial summaries, and modeling.
• Tracing contaminant pathways through aquatic systems • Quantifying water retention capabilities upstream • Identifying and prioritizing habitat restoration opportunities • Examining continuity or dissection of habitat corridors • Quantifying aquatic and wetland resource types • Facilitating ecological modeling
o Environmental Protection Agency’s Science Advisory Board (SAB)
DRAFT report titled Connectivity of Streams and Wetlands to Downstream Waters: A Review and Synthesis of the Scientific Evidence
• The report examines the effects that headwater and ephemeral streams and wetlands have on larger downstream waters.
