Well, the flow varies as you reach the source, being about 7,000 M3/sec as it exits Lake Ontario. In any event, my intent is to have a tolerable degree of outflow diverted from the great lakes, esp in flood years during the melt, when many downstream areas are flooded when the melt is compressed in time by 2 hot spring weeks. Aquifers can be recharged at many permeable perimeters points and the Ogallala aquifer https://en.wikipedia.org/wiki/Ogallala_Aquifer https://en.wikipedia.org/wiki/Ogallala_Aquifer Has a number of places in it's East and North East that can be used as recharge areas. As you see from the wiki, it has been drawn down for decades. Canadians are full of 'not one drop' fanatics - who would prefer to see it go to the Atlantic - flooding each spring, along the way - instead of helping the US drought. My feeling is the peak snow melt could be diverted to the South and West towards suitable recharge points to mitigate this drawdown - it will take years to build and years to work, but in the end it needs to be done. The forces of warming climates over the next 50 years could make the great plains into the Great US central desert - where nothing either lives or grow. It is a bleak prospect, but we screwed the earth and we must live through it - one way or another - wetter is better.
