I left my watch and phone in the car but Lakeshore appears to still be erupting about every 4-5 minutes with heights of 1-2 feet. I only observed 3 eruptions. |

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). |

Overflowed and heavily upwelled.
An attempted fill occurred at 1715, but winds have kicked up on the lake and waves are splashing cupfulls of water into the crater repeatedly. |

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. |

At 1154, the large/left vent erupted to 2 feet or slightly more. At 1155, water rose in both vents, but then just paused before dropping to the level seen after eruptions. Aborted eruption. |

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 was trying to erupt with minors about every 4-5 minutes but somewhat less than half resulted in an eruption. The others showed heaver overflow and some bubbling only. |

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. |

Lakeshore is cycling and very close to having bona-fide minors. Surges are reaching 1' at the peak of the cycle but it's erratic and varies in strength. |

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. |

Eastern vent engaged in very low to low splashing from a low pool immediately following the 1802-1803 eruption. This continued to 1808, when a brief pause occurred. Resumed low pool low splashing at 1808 to 1811. Pool higher , with roiling and occasional low splashes at 1812. Resumed low pool low to very low splashing at 1812 to 1814. |

Pressure pool (large vent) is above water and lightly boiling when during overflows which are occurring every ~5 minutes. There is still a trickle of lake water overflowing into the main vent so it is not bubbling, but the water level rises in conjunction with the pressure pool. |

Main vent was observed to be boiling 6-12" high today with the feature doing temporary overflows. It was not boiling yesterday.
I will check it out early this evening. |

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. |

Main vent was taking on more water from wave action. The one cycle I watched still had boiling to 1-2 feet in the pressure pool, but the main vent only overflowed, no bubbles. |

Both vents cycling about every 3 minutes. Pressure pool would overflow briefly, then drop about 4 inches and boil to 1-2 feet. Main vent was taking in some water from small wave action, but cycled up to overflow with variable bubbling to as much as 4-6 inches. Low water level was about 3-4 inches below rim. |

Lakeshore is now exposed from the lake. The main vent only had an occasional small trickle flowing into it from the periodical wave.
Currently cycling up and down on 4-5 minute cycles. At peak of the cycle, pressure pool will have boiling/splashing 1-1.5 feet high. No boiling from the main vent at this time. |

At 1013, the smaller vent on Lakeshore Geyser made a valiant effort to possibly erupt, with a few decent splashes. But at 1015 the water levels dropped to below overflow and the bubbling lessened (but didn't completely stop). The larger vent was splashing and rising up a foot or so on occasion as it has been doing since the water level of the lake dropped enough. |
