BASIN ACCUMULATED OVERDRAFT VERSUS <br />STORAGE LOSSES TO ADJACENT BASINS <br />Is 40,000 <br />35,000 <br />30,000 <br />25,000 <br />20,000 <br />.� 15,000 <br />10,000 <br />5,000 <br />0 <br />0 100,000 200,000 300,000 400,000 485,000 <br />OCWD Accumulated Overdraft (AF) <br />Example Calculation: <br />Assuming Metropolitan had 60,000 AF stored in the OC v D basin and the basin's <br />accumulated overdraft was 400,000 AF. Metropolitan would incur storms losses of 0,6% or 360 <br />AF for the year. ((6,000 AF lost / 1.0 MAF) x 60,000 Ala = 360 AF'). Using the same example, <br />if the basin's accumulated overdraft was 200,000 AF, Metropolitan would incur losses of 2.1 % <br />or 1,260 AF. <br />First Amendment 7 Groundwater Storage <br />
