OCAP Targets for Lahontan Reservoir are set by the Bureau of Reclamation for the end of each month.  The target is based primarily on the forecasted flow of the Carson River at Fort Churchill for the April through July period.  The average flow for the last 30 years at Fort Churchill is 178,000 acre-feet.  The Natural Resources Conservation Service (formerly known as the Soil Conservation Service) prepared a mid-December 2006 forecast of 100,000 acre-feet, which is 56 percent of average.  The January 2007 end of month storage target for Lahontan Reservoir is 215,200 acre-feet.  This includes 23,100 acre-feet of incentive credit in the reservoir, accumulated over the last six years by exceeding the required OCAP efficiency.  As of December 28 the storage in Lahontan Reservoir is 160,123 acre-feet.  Because the projected end of January storage will not reach the target without diversions from the Truckee River, diversions up to 44,100 acre-feet are allowed.  Base flows in the Truckee River for January produced by maintaining Floriston Rates at Farad of 400 cfs will result in only about 27,000 acre-feet available to divert.  TCID has elected to forego diversions to repay the recoupment debt with the incentive credit that has accumulated in Lahontan Reservoir.  It will take about 21 days to repay this amount.  As a result, diversions will be discontinued beginning January 1, 2007, and ending January 21, 2007.  After January 21, 2007, diversions to Lahontan will commence by diverting all the water that is in the river.  The table below will be updated throughout the 2007 season to show the revised targets and allowable diversions each month.
