Shasta County, CA: the closest actual trend
The closest qualifying well to Shasta County is 63 miles away in Siskiyou County, CA, where the trend runs declining faster than most declining counties.
Shasta County itself has no monitoring well with enough history to call its own trend, so treat this as a regional estimate, not Shasta County's own number. If you own a well here, comparing your own depth log against this regional figure is worth doing before assuming either way. See Siskiyou County, CA's full page. See the no-data guide for why a county this close to a qualifying well still doesn't get its own number.
