Conclusions1. Groundwater Occurs in Both “Basin-Fill” and “Basalt” Units
2. Groundwater in Deep vs. Shallow Water-Bearing Zones is Connected
3. Groundwater & Surface Water are Connected: Seepage & Springs
4. Groundwater Pumping Causes Surface Water Depletion
5. Depletion Seasonal Magnitude & Duration Variesa. Depletion via Springs is More Acute than via Seepageb. Depletion is Less Acute with Distance c. Depletion is Less Acute with Greater Well Seal Depth
6. Depletion Total Volume Remains the Same Over Time

Water Resource Management Consideration1. Recognize & Decide
a. Recognize Total Depletion Volume Over Time Remains the Sameb. Recognize Maximum Rate & Duration of Depletion Can Varyc. Decide What to Manage
2. Managing Acuteness of Depletion Rate & Durationa. Continuous Well Casing & Seal Through “Basin-Fill” Into “Basalt” b. Greater Distance Between Wells & Surface Water c. Avoid Depletion via Springs as Much as Possible
3. Managing Depletion Maximum Rate & Volumea. Determine Maximum Monthly Depletion Acceptable b. Determine Maximum Monthly GW Pumping Rate Acceptablec. Determine Maximum Annual GW Pumping Volume Acceptable
