Many isolated wetlands connect to the 1050 m 3 /s river during flood events Sagin et al. 2015
Wetlands that connect to the river (category “1”) have higher oxygen, and lower ammonia than those that don’t get flushed as often Ammonia Dissolved Oxygen 4 15 3 10 2 5 1 0 0 1 2 3 4 5 1 2 3 4 5 Windy Lake Ben’s Lake Mackinnon et al. 2015

Two major changes: Seasonal and Daily flows Not enough water in spring & summer Hydropeaking creates havoc for Too much water in winter wildlife and for transportation Mostly due to Gardiner Dam Due to EB Campbell Dam • Mimic the natural pattern of water flow • In spring and summer, increase Flood the delta in the spring and summer • minimum flow In late fall and winter, decrease • EB Campbell can only do so much maximum flow

Our Rivers Depend on Reconciliation “Reconciliation means finding the courage to look at our past with eyes wide open, unafraid to see our country at its worst, and then, humbly, take steps to heal the damage done.” (Ry Moran – Director the National Center for Truth and Reconciliation University of Manitoba
