The reconstruction of the Oroville Dam Spillway has been a lengthy task.

The DWR met their goal of having the new spillway constructed by November first, but the work still isn't finished.

The construction of the new spillway was just the first phase of the project.

Crews are still finishing the sealing of the concrete slab joints and drain lines behind the main spillway.

Now workers are ready to begin phase two.

Crews will be focusing on completing the underground pile wall work around the emergency spillway.

Last week the DWR began doing controlled blasts in the areas between the pile wall and the emergency spillway.

They'll be excavating more rock, preparing the foundation, and placing a roller-compacted concrete splash-pad.

The DWR says the controlled blasts are expected to be done every other day, but that is subject to change as needed.

This phase of the project is estimated to be completed by the end of December. There will be about another month and a half of work.

The DWR says they're expecting this second phase of the reconstruction project to be finished by the end of January 2018.
