<br />Water Year 1989 <br /> <br />The projected plan o[ operation [or Fontenelle Reservoir [or <br />water year 1989 is to refill the reservoir by the end ofthe runoff <br />season. Due to the installation of a diaphragm wall located <br />along the centerline axis of the dam, some restrictions are set <br />on refilling the reservoir. Refilling recommendations are for <br />a maximum filling of 1 ft/day above elevation 6,480 feet, and <br />an unrestricted ruling rate below this elevation. <br /> <br />Based on reasonable maximum inflows, releases will average <br />about 550 cfs until the spring runoff when releases are <br />expected to peak between 4,500 and 5,000 cfs. Assuming <br />average inflows, releases will range from 400 cis to peak flows <br />of 2,500 cfs during maximum inflows. Under minimum <br />inflows, releases will be 400 cfs for October through April, and <br />800 cfs for the remainder of the water year. Fontenelle <br />Reservoir is expected to fill under the flfst two monthly inflow <br />scenarios, and fIll up to 75 percent under the last scenario. <br /> <br />FONTENELLE STORAGE <br /> <br />1000 ACFlE-FEET <br />010 <br /> <br /> <br />300 <br /> <br />... <br /> <br />.00 <br /> <br />,.. <br /> <br />"0 <br /> <br />00 N 0 ~ F W A M ~ ~ A 8 0 N D ~ F.U A U ~ ~ A 8 <br />ACTUAL 1988 AND PROJECTED 1989 <br /> <br />PROJECTED OPERATION 1989 <br />REASONABLE MAXIMUM RELEASES <br /> <br />1000 OF. <br />. <br /> <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />MOST PROBABLE RELEASES <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br /> <br />. <br /> <br />REASONABLE MINIMUM RELEASES <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br /> <br />N D J F M A M J JA S 0 <br /> <br />6 <br />
