25369 09 May 2023 @ 1000 09 May 2023 @ 1055 Tara Water level out of sight, a rough guess would be that it's about 1.5 feet below the rim at its lowest. Appeared to be fluctuating up and down with boils at the peaks every 1-2 minutes. The boils varied in height but never reached above the rim during my observation. I saw water 1-2 feet above the rim from the OFI parking lot at 0944; due to the more sustained nature of that activity I think it was an eruption but I didn't catch it in the act from up close.
25305 30 Apr 2023 @ 1935 --- SantaFe108 Water level was out-of-sight at 1420. Now it is ~6 inches below the rim and gurgling.
25096 12 Mar 2023 @ 1315 --- Janet Jones Gently steaming. Looked post-eruptive by some hours - no water seen in person or in photos taken.
21861 09 Jun 2022 @ 0911 --- SantaFe108 Boiling and down about 2 inches from the rim.
21456 24 May 2022 @ 0701 --- Micah Kipple Within 2 inches of the rim and boiling.
17058 12 May 2021 @ 1037 --- Micah Kipple Within 6 inches of the rim and boiling. I'd be watching for Little Squirt.
14589 11 Jun 2020 @ 0749 --- K.Cooper 6 inches below overflow, strong boiling
14238 26 May 2020 @ 1052 --- Janet Jones Water level is still in sight with nice boils up to a foot high that don’t clear the rim top. Little Squirt ie and “Pygmy” is noisily sputtering and steaming.
14218 19 May 2020 @ 1312 --- Janet Jones Silver Spring's water level rose since yesterday to about an inch below the back catch basin. No boiling seen.
14201 18 May 2020 @ 1437 --- Janet Jones Water was visible with boiling, but water level was about 8" below the "back catch basin." Little Squirt was dry.
14168 10 Apr 2020 @ 0936 --- CraigC Steam seemed to be significantly heavier than observed previously. It was intermittent between heavy and what I would consider regular. No vertical water was observed, but visibility was not ideal. This activity was observed for about 30 minutes on the webcam.
13955 17 Oct 2019 @ 1440 --- JarnoO Ever since around the time Little Squirt was first observed, I've been seeing intermittent bursts of steam lasting about <=1m occurring from Silver Spring at a frequency of about once every 2-5 minutes or so. Never saw any water, but I think it might be actual eruptive activity which never makes it out of the crater.
10679 29 Oct 2018 @ 1232 --- udo superheated edge boil and doming to 4 inches on far side of pool
10284 18 Sep 2018 @ 1125 --- Micah Kipple Periodic heavy boils above ground level.

8807 20 Jun 2018 @ 0741 --- mhreed ~2 inches below overflow. Gently pulsing.
8109 04 May 2018 @ 1126 --- Janet Jones Water 3-4" from top of the rim. Water in the back "catch basin" (for lack of a better term).
8071 03 May 2018 @ 1649 --- Micah Kipple Within 10 cm of the rim.
4059 05 May 2017 @ 1620 --- Janet Jones While Little Squirt was still erupting, Silver Spring didn't drain and erupt. Instead, the water level had dropped to about 4-6" below the rim top and was occasionally splashing from the center of the pool.
4058 05 May 2017 @ 1140 --- Janet Jones Water overflowing the crater including overflowing from back catch basin.
