Table 6. Calculated quarterly withdrawals by pumping region and year based on analysis of more restrictive drain-constraint limit for scenario Drain_10, upper Klamath Basin, Oregon and California, 1970–2004. 


[Scenario Drain_10. Drain-Discharge constraint limit is 10 percent. Shading used to emphasize years in which groundwater demand is not met. All withdrawal volumes are in acre-ft. Abbreviations: KLV, Klamath Valley wells; NTL northern Tule Lake wells; STL, southern Tule Lake wells; LKL, Lower Klamath Lake wells; KLR, Klamath River wells; Q3, third quarter; Q4, fourth quarter]
