still very high and overflowing. There are a number of small holes in the shallow part of the pool with bubbles coming to the surface everywhere, not just the boil in the main part of the pool. |

Full and overflowing steadily in a fairly wide overflow channel with yellow microbes growing in it. The area between Surging and the boardwalk that has acted as a mud pot in past years was almost covered by water from Surging - and more small openings have appeared there. I think this is the highest water level I've seen from Surging. A couple of very small trees on the berm between Surging and the Paint Pots area were dying or dead. |
