Reservoir <br />operation studies, based on historical flows of the Florida River, indicate <br />that water supplies available from project facilities will be adequate to <br />meet this requirement in all but exceptionally dry years. The average water <br />supply available for delivery to farmers during a period of years comparable <br />to the 1928-56 study period (which includes the driest series of years on <br />record) would be 94 percent of estimated requirements. An average of seven <br />out of ten years would have a water supply adequate to meet all crop require- <br />ments. The project water supply and requirements are summarized in table 8. <br /> <br />- 17 - <br />
