A precision gravity network consisting of approximately 50 stations was established to monitor the Lassen geothermal system. The network was surveyed during the summer of 1982 and tied to a similar network established in 1981. Measurements yielded relative gravity values at the network stations with average uncertainties of 0.007 mGal (1 computed standard error).
