Sugar Pine Dam

Blackburn Consulting prepared an Initial Instrumentation Report for this 205 ft high, 6,920 acre-feet, zoned earthfill dam constructed by the US Bureau of Reclamation (USBR) in 1982. The dam is now owned by the Foresthill Public Utilities District under the jurisdiction of the state Division of Safety of Dams. The report includes an evaluation of all instrumentation, including embankment measuring points; concrete structures deformation; extensometers; inclinometers; rock slope deformation; twin-tube, pneumatic and porous-tube piezometers; seepage monitoring; and earth pressure monitoring. Recommendations included elimination of some instruments from future monitoring, and continued monitoring of other instruments for future performance evaluation. Annual Instrumentation Reports will be based on this report.
