1 Niagara Escarpment…

1 Niagara Escarpment important recharge area in Melancth water surplus recharges the dolostone Aquifers upgradient of the 455 m asl contour Escarpment slope spring line. The local water surplus is equivalent to 30 to 40% of the dry season base flow at Wasaga Beach. The late summer dry weather flow observations in the Pine River Valley above Terra Nova are about 1,000 L/sec, further downstream at Everett at about 750 L/sec and in the Nottawasaga River at Edenvale upstream of Wasaga Beach at about 5,000 L/sec. Downstream losses on the Pine River valley are likely due to recharge and groundwater underflow at stream gauging stations and near Everett due to agricultural irrigation withdrawals.
