Since the cost of alternative water supplies avail 10 able to the Metropolitan Water District at the present time 11 is about $150 per acre-foot. And this alternative water suppl 12 is our water supply from the State Water Project, and this 13 data $150 per acre-foot represents the cost that is given by 14 the Department of Water Resources to us, or for alternative 15 waters fr an that source. 16 This $15D per acre-foot, would mean that each I 17 acre-feet of reservoir capacity, which is now reserved for fl 18 control regulation purposes, could result in a loss of water 19 worth a hundred and fifty million dollars, and this is as far 20 as the Metropolitan Water District is concerned. 21 The effects of lesser amounts of storage space bein 22 reserved for flood cmtrol purposes can be offset by increase 23 in downstream channel capacity. Such increases in channel 24 capacity would not only reduce damages due to high river flows 25 during flood events, but would also permit .... .,pid .......'1. , ,
