Summary Hearing local community concerns, University of Saskatchewan researchers wanted to understand how the nutrient and potential contaminant (mercury and other trace metals) levels of wetlands in the Slave River Delta are influenced by how often they are flooded by the River. To do this, we worked collaboratively with the Deninu Kųę́ First Nation, Fort Resolution Métis Government, and the Government of the Northwest Territories.We found that the frequency of flooding does influence the water and sediment chemistry of the wetlands. But less frequent flooding does not mean that levels of mercury or other metals will increase in food webs.
Local Relevance This research investigates the effects on the frequency of flooding in the Slave River Delta.
