While waiting for sunset, after everyone had left and it was very quiet I realized the waterfall at the end of the runoff was cycling between landing on the talus and then landing out into the lake. Runoff is apparently cycling, but I can’t visually see it in the channel. |

Black Pool is a clear bright blue. On May 10 I made a note that it was Blue-green, leaning more toward blue than green. Today all notion of green was gone. |

In overflow and brilliant blue. Amount of overflow seems to change based on runoff channels. |

Really a lovely sapphire green color. Overflowing with some channels partially dry as was often seen when normally overflowing before - part of what I’m guessing is a cyclical bit of extra overflow. |

Overflowing from three spots: a trickle from two spots on the south end and a bit more than that from one spot on the north end. Dry patches in one of the small south runoff channels may indicate rising and falling of the pool over time, but in the ten minutes I was here, I did not observe any visible changes in the amount of overflow or the pool water level. |

Black Pool is back in overflow. Just a trickle, but it’s there. |
