the effects of a forest fires on water flow and quality in lakes surrounding a northern ontario mine
abstract
water quality and quantity can be greatly impacted following a forest fire, but fire impacts
can vary based on fire intensity, watershed topography, and post-fire precipitation events. forest
fires are an important contributor to the natural regeneration of forests. watershed monitoring is
important for gaining a greater understanding of forest fire impacts on water resources, thus
helping to improve interpretations of overall fire effects. the aim of this study was to reveal fire
disturbance impacts on water quality characteristics surrounding a mine site. the forest fire likely
resulted in increases in dissolved organic carbon and ammonia concentrations, especially
downstream of the mine site. however, no increased metal concentrations occurred after the fire.
increased flows and frequency of peak flow events in the watershed following the fire did occur,
which can impact water quality in ways that were not measured.
