“…Stewart and Kantrud (1972) and Millar (1976) distinguished between freshwater ponds (EC, < 500 µS cm −1 ), moderately brackish ponds (EC between 500-5000 µS cm −1 ) and brackish-saline ponds (EC > 5000 µS cm −1 ). The reasons for these differences in salinity are understood to be a function of how the ponds interact with the groundwater and surface runoff.…”

Abstract. The glaciated plains of the North American continent, also known as the "prairies", are a complex hydrological system characterized by hummocky terrain, where wetlands, containing seasonal or semi-permanent ponds, occupy the numerous topographic depressions. The prairie subsoil and many of its water bodies contain high salt concentrations, in particular sulfate salts, which are continuously cycled within the closed drainage basins. The period between 2000 and 2012 was characterized by an unusual degree of climatic variability, including severe floods and droughts, and this had a marked effect on the spatial distribution, water levels and chemical composition of wetland ponds. Understanding the geochemical and hydrological processes under changing environmental conditions is needed in order to better understand the risk and mitigate the impacts of future soil and water salinization.Here we explore salt dynamics in the prairies using field observations from St. Denis, Saskatchewan, taken mostly over the last 20 years. Measurements include meteorological data, soil moisture, soil salinity, groundwater levels and pond water volume, salinity, and chemical composition. The record includes periods of exceptional snow (1997, 2007) and periods of exception rainfall (2010, 2012), both of which resulted in unusually high pond water levels. Measurements indicated that severe pond salinization only occurred in response to extreme summer rainfall. It is hypothesized that since rainfall water infiltrates through the soil towards the depressions, while snowmelt water flows mainly as surface water over frozen soils, they have markedly different impacts on salt transport and pond salinization. Whilst this hypothesis is consistent with our conceptual understanding of the system, it needs to be tested further at a range of field sites in the prairies.

“…Landform position and plant communities were excellent indicators of the water regime and sodic content of the soil (Seelig et al, 1990). Vegetation changes associated with soil gradients have been documented for other wetlands (Stewart and Kantrud, 1972;Cowardin et al, 1979;Richardson et al, 1994). As reported by Seelig et al (1990), the highest ESPs in the study area were found in soils located at intermediate positions, whose plant communities were dominated by Distichlis spicata spp.…”

“…About 450 of these wetlands were within the federally managed bounds. All wetlands were categorized as fresh to slightly brackish ponds and classified according to an early version (Stewart and Kantrud, written commun., 1963) of the Stewart and Kantrud (1971) wetland classification system. The dominant vegetation surrounding each wetland was classified once in each decade (early 1960s, 1970s, and 1980s).…”
