Summary appraisals of the nation's ground-water resources – Pacific Northwest region
Bruce L. Foxworthy
1979, Professional Paper 813-S
The Pacific Northwest Region's ground-water reservoirs are capable of providing large additional fresh-water supplies; these reservoirs become more important as undeveloped surface-storage sites and unapportioned surface-water supplies dwindle. Withdrawals of fresh water from all surface and underground sources are increasing; they may rise from the rate of 30 billion gallons...
