Key to PRW Abbreviations: P = Main stem of Presumpscot River, BB = Baker Brook, BL = Black Brook, CW = Colley Wright Brook, DG = Douglas Brook, DB = Ditch Brook, IN = Inkhorn Brook, L = Little River, M = Mill Brook, N = Nason Brook, OB = Otter Brook, PI = Piscataqua River (not the same as one at ME-NH border), PL = Pleasant River, TA = Tannery Brook.
The "% complete" column indicates the number of samples actually
collected compared to the number of samples intended for collection. PRW has
8 sampling events per season, so if only 4 samples were collected for the season
the completion rate would be 50%.
