Table 3. Calculated quarterly withdrawals by pumping region and year based on analysis of less restrictive drawdown-constraint limits in the California part of the groundwater-management model for scenario DD_1, upper Klamath Basin, Oregon and California, 1970–2004. 


[Scenario DD_1. Seasonal drawdown limit is 37.5 feet and year-to-year drawdown limit is 4.5 feet at constraint locations in California. 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]
