Changing climates will likely result in more frequent midwinter ice jams along many Canadian rivers, thereby increasing the likelihood of flood damage and environmental changes. Therefore, the possibility of more frequent ice jams has to be considered during the planning of flood damage reduction measures, the design of waterway structures, and the enactment of measures to protect the environment. As a case study of midwinter jamming, four winter breakup and jamming events that occurred along an upper stretch of the Saint John River during the 1990s are described and the implications of similar midwinter jamming are discussed.Key words: breakup, river ice, climate change, ice jamming, ice thickness, winter, winter thaw.

This case study of a 7200 ha. urban watershed illustrates the challenges involved in using sediment quality surveys to determine pollutant sources and trends. Trace metal and chlorinated hydrocarbon analyses were performed on sediment samples obtained from 33 stream, 24 street, and 1 lake (sediment core) locations. The stream and street sediment survey was initially conducted in 1973 and repeated in 1993. Consistent results across all sediment media indicate significant reductions in Pb, PCB, and DDT levels have occurred since the 1970's as a result of source controls. While streambed results indicate Hg and Mn levels have increased significantly since 1973, neither a spatial analysis of streambed results or a comparison to street concentrations indicate a source for the increase. A more detailed geo-chemical analysis and/or atmospheric contaminant survey may provide more conclusive source information.
