This is an increase from last August <br />by 458 AF or a drop in conservation of 6.2%. Weather conditions showed drier patterns for rainfall <br />with 0.39" less of rainfall with respect to August 2017. August of 2018 was slightly cooler by about <br />0.22 degrees compared to last year. RPU is still within the historical production range from 2013 <br />to 2017 as shown in Figure 1. Figure 1 also shows that RPU's projected annual urban water <br />production in 2018 is 65,400 AF which is below the compliance target specified in SB X7-7 (i.e. <br />20% reduction by 2020). The projections for the 2018 urban water production is based on current <br />trends of increased consumption and can be affected by the permanent water prohibitions <br />implemented by the State and/or the return of drought conditions. The projected annual urban <br />water production is also below RPU's current potable rights, which potentially can maximize <br />RPU's passive assets by 6,500 AF through wholesale to Western Municipal Water District. <br />Basin Groundwater Levels <br />Groundwater levels in the Bunker Hill, Rialto -Colton, and Riverside North basins are continuing <br />to show a long-term declining trend, while groundwater levels in the Riverside South Basin remain <br />relatively stable as shown in Figure 2. Groundwater levels in the Bunker Hill Basin are continuing <br />their annual summer descent, and will soon be approaching their seasonal low point for the year. <br />Water levels in Bunker Hill are approximately 2 feet lower as compared to August of last year. <br />Water levels in the Rialto -Colton and Riverside North basins are 20 and 15 feet lower as compared <br />to August of last year, respectively. The Riverside South Basin is approximately 2 feet lower as <br />compared to August of last year. <br />Page 117 <br />
