I’ve been taking National Ground Water Awareness Week to think a little more than usual about groundwater. My KQED Quest blog post yesterday, on Bay area groundwater, mainly focused on the South Bay. Oakland’s not a big groundwater town.
The rancheros and early Anglo settlers here all dug wells, of course. As I understand it, Dunsmuir House still has an operating well, the Pardee Home has a water tower that suggests the presence of a well, and some of the other old properties must have them too. Some long-standing Oakland industries probably have wells, and maybe the golf courses too. I don’t know a lot about it.
But municipal water service from Oakland’s earliest days exploited local surface water, starting with Temescal Creek and ending with San Leandro Creek (see the two dams post). Lion Creek supplied laundries in the area near Mills College once called Laundry Canyon. Today we’re all served by East Bay MUD with clean Sierra runoff from the Mokelumne River watershed. In Oakland, surface water rules.
Today groundwater is off the radar here. Sure, we have to clean it up where old gas-station tanks used to leakthis monitoring well is from one of those. It seems to me that the aquifer west of Chabot Dam, in the alluvial fan crossed by San Leandro Creek in far East Oakland, must have good potential, and so would Fruitvale and Temescal. San Francisco is opening up its formerly used aquifers to serve emergency purposes; we ought to look into that too. Why go to such expense to clean up the groundwater and not get some sustainable use out of it at the same time?
