Patagonia Lake Dam

In 2009, with cooperation from ASP, HGI instrumented the face of the dam with 533 resistivity electrodes, placed along four HRR transects. The dam was characterized for the baseline survey, from which all subsequent surveys will be compared. Decreases in resistivity indicate an increase in saturation and it is anticipated that problems deep in the dam’s core can be detected long before they manifest at the surface.
