To the north of the mud volcano, run-off waters are now being diverted toward agricultural irrigation channels.
[1] Run-off waters are flowing over the North dam.
[2] A small retention basin to the north-west of the volcano is now submerged.
[3] Run-off waters are spilling over into an agricultural irrigation channel (highlighted in blue). Another channel to the south of the volcano is diverting waters toward the Bali Sea via the Porong River.
[4] The recently built retention basin north-east of the volcano backs onto another agricultural irrigation channel to control the discharge of run-off waters.
[5] New earthworks.

[1] Run-off waters have submerged the corner of the south dam. Mounds of earth torn away from the dam are still visible.
[2] Water in the south-east basin is being drained off by a canal into the Porong River. The river’s colour is no longer changed by the mudflow now that the south dam has been breached.

[1] Two large blue-grey basins north and south of the crater are holding back the mud.
[2] Mud in the white basin to the west is being dried out to solidify this side of the volcano. Run-off waters are pooling in the southern part of the basin.
[3] A channel has been dug along the dam of the large southern basin to drain off mud directly into the Porong River.
[4] Run-off waters are being held to the east of the volcano in two dark blue basins, one dammed off and the other still open on one side.

[1] A new dyke protects a railway bridge
[2] Channels have been dug in the southern basin. They drain off mud to an internal circular basin on the east side. With the channel dug along the western dam, a network is organized to control the draining of sludge into the river.

[1] The new dam started in June 2008 has been extended on the west side along the railway, and along a stream on the north side.
[2] The channel is silting up where it discharges into the Porong River. A white fan-shaped deposit of mud has formed and is choking up the river.
[3] The river changes colour after the old highway bridge. Mud is being pumped and drained away through a pipe on the roadway.
[4] The pumping station has been set up on the old highway overlooking the inner retention basin where the runoff water channels converge.

The mud is drying up in some places around the volcano. Several factors explain this change: the summer monsoon or dry monsoon contributes to evaporation, the pumping and the drainage into the river is effective, the eruption is decreasing in intensity.

[2] Sheets of mud around the volcano appears in white, displaying a recent drying up.

[1] The opening in the dyke is marked by two white structures.
[2] The centre of the south basin is drying up. The mud is flowing by two lateral canals.
