Table 5. Calculated quarterly withdrawals by pumping region and year based on analysis of more restrictive drawdown-constraint limits for scenario DD_3, upper Klamath Basin, Oregon and California, 1970–2004. 


[Scenario DD_3. Seasonal drawdown limit is 20 feet, year-to-year drawdown limit is 2 feet, and 10-year drawdown limit is 20 feet at all constraint locations. 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]
