The goal of this project was to investigate the influence of a large inland lake onadjacent coastal freshwater peatlands. The specific aim was to determine the source ofgroundwater for three differently formed peatlands located on the southern shore ofLake Superior. The groundwater study was conducted at Bete Grise, a peatlandcomplex in a dune-swale system; Pequaming, a peatland developed in the swale of atombolo; and Lightfoot Bay, a peatland developed in a barrier beach wetlandcomplex.To determine the source of groundwater in the peatlands, transects of sixgroundwater monitoring wells were established at each study site, covering distinctlydifferent vegetation zones. At Pequaming and Lightfoot Bay the transects monitoredtwo vegetation zones: transition zone from upland and open fen. At Bete Grise, thetransects monitored dunes and swales. Additionally, at all three sites, uplandgroundwater was monitored using three wells that were installed into the adjacentupland forest. Biweekly measurements of well water pH and specific conductancewere carried out from May to October of 2010. At each site, vegetation cover, peatdepths and surface elevations were determined and compared to Lake Superior waterlevels. From June 14 – 17, July 20 – 21 and September 10 – 12, stable isotopes ofoxygen (18O/16O) ratios were measured in all the wells and for Lake Superior water. Amixing model was used to estimate the percentage of lake water influencing each sitebased on the oxygen isotope ratios.During the sampling period, groundwater at all three sites was supportedprimarily by upland groundwater. Pequaming was approximately 80 % uplandgroundwater supported and up to 20 % Lake water supported in the uppermost 1 mlayer of peat column of the transition zone and open fen. Bete Grise and LightfootBay were 100 % upland groundwater supported throughout the season. The height ofLake Superior was near typical levels in 2010. In years when the lake level is higher,Lake water could intrude into the adjacent peatlands. However, under typicalhydrologic conditions, these coastal peatlands are primarily supported by uplandgroundwater.
