Chris Ferrar's Groundwater Assessment Protocol

The Word file gives a description of one possible way of handling the scoring of ground water use, storage, and recharge. The Excel file shows graphs of the example data. This is focused on one well. To score for multiple wells, one approach would just sum the individual scores and divide by the number to get an average for each group (perhaps the median would be more robust). The grouping of wells could be geographic or depth, or aquifer, or some mix of these criteria. The relative area monitored by a particular well could be accounted for by the method Alex showed us at the last meeting, but should only include wells for a particular group. As far as groups go, Sonoma could be divided by upper valley (Glen Ellen to Kenwood) and lower valley or split lower valley in two (this might be important for looking at the saline water intrusion problem and to separate out the City from rural areas). Napa is bigger and maybe more complicated, but certainly MST and Carneros could be treated individually, then maybe an upper and lower valley division but that might not be needed. If DWR has aquifers for each well in their network that could be used for Napa Valley. --Chris
