Will drains be properly accounted for in Zone Budget? I have a drain in a zone and the drains are discharging 6,269 cf/day according to the MODFLOW output file. Looking at the Zone Tab in Flow Budget, the drains category is showing 0 cf/day. Also, the Total Out in the MODFLOW output file is 12,652 cf/day, but it is only 1,249 cf/day in the Zones tab of the Flow Budget. If I run the USGS Zone Budget from the menu, The correct drain flow is shown in the budget, but the total out is only 8,853 cf/day which is different from both the previous two numbers. Which numbers are correct?
