Some people are wondering about Lakeport sewage water being piped to the Geysers geothermal field to recharge the project.

But I think the subdivision in trouble is north of point A in this map, and the water is being injected in the Geysers area near point B, so even if subsidence was being caused by the loss of local water, how can the mysterious water that is bubbling up in the subdivision area itself be explained?

I'm wondering about the missing seismic energy here:
PRELIMINARY INVESTIGATION OF AN ASEISMIC 'DOUGHNUT HOLE' REGION IN THE NORTHWEST GEYSERS, CALIFORNIA

That's a big mystery when predicted energy from fluid injection goes missing. Had it been transferred elsewhere?

Normally increased seismic activity is thought to cause groundwater to sink, not rise. Water is mysteriously disappearing in the Lassen Peak volcanic area.

Underground water in eastern Shasta County mysteriously disappears

Stephen Wolf thinks something strange is happening underground in eastern Shasta County and it is draining water wells and maybe even causing sinkholes and subsiding pavement.

A retired marine geologist with the U.S. Geological Survey, Wolf said he has seen what is happening in eastern Shasta County before. After the 1989 Loma Prieta earthquake, water well levels in the area of the quake fell significantly, he said...

This is quite a distance from Mount Konocti.

The water in Lakeport might not be a geological mystery, after all. A consultant found that a couple of county water pipes were leaking at a rate of 20-30 gallons a minute back in March. The county denies this would produce enough water to be causing the problem, but that sounds like a big leak to residents.
