We completed our post-drainage site visit on 24 July, roughly one week after completion of the lake drainage.
The lake started overtopping the dam on Sunday 7 July in the morning and reached its maximum level shortly thereafter.
The water in Suicide Basin has gone up by 8.25 m over the last week.
The water in Suicide Basin has gone up by 7 m (~1 m per day) since our last site visit on 21 June.
The water in Suicide Basin has gone up by 14 m (~1 m per day) since our last site visit on 7 June.
We drilled in a new melt wire at the basin entrance, deployed the drone, surveyed the lowest point in the dam, and deployed additional air temperature sensors higher up in the basin.
Using the drone-based elevations models from last year, we derived an approximate vertical scale for the rock face on the north side of the basin.
We installed the non-telemetered water level gauges, webcam, temperature and precipitation gauges, and the on-ice GPS.
We were up in the basin on Monday and Tuesday to survey points, fly the drone and recover some of our instruments.
