This study examined the potential for electrical
conductivity (EC) to serve as an indicator of groundwater-
driven wetland-stream connectivity in the Prairie Pothole
Region. Focus was on the Broughton
’
s Creek Watershed
(Manitoba, Canada) where thirteen wetlands and a creek were
monitored in 2013
–
2014. A connectivity index (CI), comput-
ed by incorporating EC data in a hyperbolic solute export
model, identified a potential for both shallow and deep
groundwater-driven wetland-stream connectivity to occur, al-
though shallower connections were rarer. Both raw EC and CI
values were strongly correlated to wetland volume capacity,
indicating the importance of storage and flow generation
processes for wetland-stream connectivity potential. The
proposed CI was instrumental in reaching that conclusion,
making it a simple yet physically-based metric of wetland
behavior that should be tested in multiple environments to
confirm or infirm its validity.
