Table 1. Summary of alternative groundwater-management strategies evaluated, upper Klamath Basin, Oregon and California. 


[Shading used to emphasize the constraint limits that are changed from their base-case values. Constraint limits: OR, Oregon; CA, California; KRBA, Klamath Basin Restoration Agreement. DD_1 and DD_2, strategies with less restrictive drawdown limits at constraint locations in California; DD_3, strategy with more restrictive drawdown limits at all constraint locations; Drain_10 and Drain_05, strategies with more restrictive drains-constraint limits]
