RESEARCH PROBLEM The Canadian Boreal Forest is one of the world’s major repositories of northern forests. Increasing demands for natural resources have resulted in about 50% of the Canadian Boreal Forest being allocated for timber harvesting and for oil and gas exploration Global Forest Watch Canada, 2002]. Such activities may have direct impacts on aquatic systems [e.g., blockage of amphibian and/or fish migration corridors] or indirect impacts on aquatic systems [e.g., increases in water, sediment, and nutrient transport from cut blocks to surface waters]. While recent research activities have focused on assessing the effects of these disturbances on aquatic systems, the research needs to be conducted on the hydrological processes that control water, sediment, and/or nutrient transport from forested areas and the implications of disturbances on these processes Buttle et al., 2000; Buttle et al., Submitted]. This research project address this research need by using a combination of ground- and satellite-based methods to: [1] Characterize hydrologic linkages between land and lakes; and [2] Establish the relation between hydrologic linkages and the nutrient status of a lake. A third objective, that focused on exploring the relation between potential of hydrologic linkages between land and lakes, the nutrient status of a lake defined by “bottom up” controls and the nutrient status of a lake defined by “top down” controls as defined by the fish community in the lake was not funded and is not presented.
