OWASA Updated Operations • If one reservoir is full and the other is drawn down,
withdraw from the full reservoir • Split withdrawal when both reservoirs are full, and also split the first 100 MG withdrawn • After the reservoirs are drawn down 50 MG each, withdraw the majority from Cane Creek, less 1 MGD from University Lake • Only withdraw from quarry when supplemental flow is needed to meet demands –
