The objective of this investigation was to respond to a request for regional assistance for a comprehensive delineation of wetland habitats subject to jurisdiction under Section 404 of the Clean Water Act and all wetlands subject to National Park Service (NPS) procedures for implementing Director’s Order #77–1: Wetland Protection within the floodplain of Blow-Me-Down-Creek upstream and within the immediate area surrounding Blow-Me-Down-Dam on Saint Gaudens National Historic Site (SAGA) lands. This work utilized the U.S Army Corps of Engineers (USACE) Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Northeast and Northcentral Region (January 2012) as the primary methodology for making wetland determinations in the field. A total of 3 palustrine wetlands encompassing 7.23 acres of land were identified and delineated from 22 -25 September 2014 within the study area (Fig. 1). Observed wetland habitats were primarily a combination of palustrine, emergent, persistent, habitats (PEM1) and scrub-shrub (PSS) habitats that exhibited extensive soil saturation at the time of the investigation. All of the identified and mapped palustrine wetland systems meet both the U.S. Army Corps of Engineers criteria and the Cowardin et al. (1979) definitions of wetland habitat. No new riverine wetland systems were identified and mapped over the course of this investigation.
