Basin Spring appears to be boiling with occasional bigger boils to 6 inches to over a foot about once a minute. No eruptions seen however. Yet. |

In low to very low eruption (viewed from Three Sisters Spring overlook). Appeared to be engaged in the same cyclic behavior as on 2 August 2019. |

No eruptions from Basin Spring. Receiving a trickle of runoff from Three Sisters Spring. Basin Spring's water level cycles up & down (Examples: high water, almost at rim, at 1248 & 1301 & 1312-1315; high water event, but not very close to rim, at 1327). Some high water level events are accompanied by slight to semi-decent overflow from the southwestern arm/corner of pool. A sustained high water event occurred from 1335 to 1357, accompanied by overflow. Slight bubbling at 1353 & 1356 & 1358 from next to the western edge of the pool. Low water levels appeared to be ~0.5 to 0.75 feet below the rim/border of the pool. |
