Pool is VERY low! 2" of exposed sinter rim in front of the runoff channel. needless to say it is NOT in overflow. Pool is a milky (cloudy) opalescent turquoise blue color, has more and slightly bigger bubbles (golf ball-tennis ball sized) breaking the surface in the thumb and side closest to the boardwalk, also one area on the far side of the pool. |

clear, calm and runoff channel is damp but no obvious sign of overflow. I think the occational wind gust is forcing water over the ridges and into the channel. |

Pool us clear, greenish and mostly calm. it is slightly in overflow. It has a few occasional quarter sized bubbles that break the surface. they are mostly on the east edge of the pool by the thumb. The "3 trees" feature that is outside the pool toward the boardwalk is erupting 3" and putting a fair amount of water down Emeralds run off channel. |

30 May 2021 @ 0925 BEN VL EMERALD See Note under Steamboat
Emerald cloudy this morning (low wind) but cleared up quite a bit by the time I left. It seems like it has been alternating btwn clear and cloudy each day for a while. Echinus has also been alternating clear and murky each day. It seems that whenever ES is clear, Echinus has been that cloudy filthy brown color from last year, and visa versa. The one note where I saw something sort of interesting from a few days ago, ES was clear and Echinus was murky.

Pool was green but slightly cloudy and barely overflowing. There was a small bubbler near the edge of the pool on the side farther from the boardwalk. I saw it at 1000 and 1030 but it had stopped when we walked by at 1125. It resumed at about 1130 and the bubbles were very frequent (about 1 every 2 seconds). |

Emerald spring's pool is SLIGHTLY in overflow. It was not at around 1000. color is more aguamarine blue than green and it has some small bubbles that break the surface. The 2 bubblers in the 3 Trees area have increased in activity and are putting more water down ES runoff channel. |

color is still a cloudy milky turquoise blue. The pool has come up a bit but still not overflowing down the runoff channel. The bubbles have decreased is size and quantity. Just a few that break the surface in the "thumb" area and are the size of a Meyer 🍋 lemon! |

Emerald spring is still very cloudy, milky turquoise blue in color. Much like I've seen Cistern look like! It still has tennis ball-grape sized bubbles breaking the surface and sending out convection waves, mostly along the side closest to the boardwalk. pool is low and NOT in overflow. The 3 Trees feature on the side of Emerald, closest to the boardwalk, has 2 small vents erupting 2 - 3". I call it 3 Trees because there are 3 fallen dead trees and these vents are close to the base of those 3 dead trees. |

ES is milky turquoise blue in color with 3 areas, on the east side of the pool, that have ping pong ball - tennis ball sized bubbles that break the surface occationally and send out small convection waves. It is not in overflow. The small bubblers that I call "3 Trees" on the edge of the tree line to the south, now has 2 vents that erupt to 2 - 3" and put water down ES runoff channel. |

Emerald is very steamy this morning. It is calm, green/blue and overflowing. FYI: The small feature in the trees to the east of ES runoff channel (by where the boardwalk narrows) that I've referred to as "3 trees" has been active all summer and is really overflowing these past 3 weeks. |
