Pattern of solute movement from snow into an Upper Michigan stream
Stottlemyer R and Toczydlowski D. 1990. Pattern of solute movement from snow into an Upper Michigan stream. Canadian Journal of Fisheries and Aquatic Sciences. 47(2):290-300
Precipitation, snowpack, snowmelt, and streamwater samples were collected in a small gauged watershed (Calumet, MI) draining into Lake Superior during winter 1987-1988 to assess the importance of snowmelt patterns and meltwater pathways in the occurrence of solute pulses in streamwater. For those ions with concentrations higher in the snowpack than in the premelt streamwater, K+, NH4, and H+, the earliest snowmelt pulses had the greatest influence on streamwater chemistry. Peak winter streamwater ANC reduction was caused principally by spring melt dilution of base cations and associated alkalinity, constant high SO4 levels, and an increase in NO3.
