Water on the lake was decently calm and lake water was starting to overtake the smaller vent and lapping at the larger vent. Bubbles rising in the larger vent on occasion, but I think it's done for the summer. |

Water levels in both Lakeshore and the side pool would drop after an eruption, further after strong minors but never out of sight, and the side pool would start superheated boiling to 1 to 1½ feet which would die down through the interval. The side pool's pencil vent would splash during Lakeshore's overflows/eruptions with a fun chugging sound. Often Lakeshore would push and get to overflow but then subside, usually 1-2 minutes before the next event. Once in my observation at least two of these pushes happened in a roe, causing that interval between events to be longer. |

Fill and drain. Per Micah's notes I don't think the last eruptions I logged on 7/25 were true eruptions. On this cycle the main (back right) vent overflowed much more water than the previous one. Again, both vents are bubbling strongly when low and quiet when in overflow (right vent) or at the rim (left vent). |

Both vents are fully exposed out of the water. Cycle seems to be near constant boil in both vents and a slow fill, then a more vigorous boil that causes right vent to overflow/erupt, then both vents drain to ~8" below the rim. This cycle seems to be about 3-4 minutes long. Peak overflows observed at 06:43, 06:46, 06:49, 06:53, 06:57. |

Had a nice splash from a lower water level in the small/right vent and the water dropped a bit lower, but was back seconds later to the 4-6" below rim top. Possibly an aborted eruption. |

At 1222, there was a momentary pause in boiling in the small/right vent for 3-5 seconds. At this time the boiling in the large/right vent increased.
At 1224, there was a rise in the water level, but no eruption or overflow occurred. This was followed by the normal drop in water levels seen after eruptions with boiling resuming within a minute as had been seen most of the hour I spent here. |

1349 Walked up to Lakeshore Geyser in heavy overflow. No bubbling in larger vent until the water began to drop. No bubbles seen in smaller vent. | 1353 Overflow began. D< 1 minute. No bubbles or boiling in smaller vent, large vent stopped boiling during overflow, but vigorous boiling started on the boardwalk side of the vent as soon as the overflow stopped. | 1357 overflow began. D< 1 minute. No bubbles, just smooth overflow. | 1401 overflow began. D= 37 seconds. One bubble rose in the smaller vent. Left vent behaved as before with no boiling or bubbles during overflow, but boiling began the moment the water level dropped. | 1405 Overflow began. D= 27 seconds. No bubbles rising in smaller vent. | 1406 left the area. |

Lakeshore continues to have minor eruptions of 6” to 18” with intervals between 4-6 minutes. Both vents are active and once reaching overflow drain between 4”-6” starting a new cycle. Largest minors occurred at 15:31, 15:55, 16:14 and 16:21. |

Both pools full and light bubbling from Pressure Pool at 0953. Receded to low pools and 12-18" splashing from Pressure Pool at 0955. 1000 both pools filled before receding to low pool with bubbling and light splashing in Pressure Pool at 1002. Water levels in both pools were relatively equal throughout observation. No bubbling or splashing from Lakeshore Geyser proper. 1005 Pressure Pool back to full with splashing along rim. 1006 receded again. 1007 rolling boils and splashing. 1008 calmer with light splashing, bubbling. 1009 full pool. 1010 receded again. 1012 full to overflow with splashing along rim. 1013 low pool splashing to 12-18" height began. 1019 filled to overflow with bubbling, quickly receded to low pool with splashing after about 30 sec. Splashes to about 1ft height. 1023 filled to overflow with bubbling, light splashing at rim. It then receded to low pool at 1024 and resumed splashing. |

Western vent had frequent periods of relatively calm, light roiling-boiling-spitting, and very low to low to moderately low erupting. Water level was higher during eastern vent's overflow events and minor eruption events. Thermal imaging (FLIR) of Lakeshore Geyser's two vents measured a maximum of 204° Fahrenheit. |

Observed overflows occurred 7-9 minutes apart. This change was apparent at least 3 days ago, today was the first chance I had to confirm that overflows were less frequent than the 4-5 minute overflow cycles of 2 weeks ago.
Main vent was placid; it was only reflecting the water level change in the system. The pressure pool was boiling 1-2 feet high. Highest boils occurred 1-2 minutes after overflow was reached. |
