Outlet: (Satellite)
The existing irrigation canal was cut into the side of steep Sierra foothills, and it is at risk for landslides and rockfalls falling into the canal and cutting off the water supply. The video contains scenes of workers removing rock from above the canal.
The Canyon Tunnel is yet another water supply project in California.
The tunnel will be 12,000' (3.7km) long. The collapse was 200' (61m) into the tunnel. [modesto]
The worker who was killed was 35-year-old engineering advisor Twyla Capurro. She is survived by two children.
This scene is at the outlet.

I've read before that the rock in California is "incompetent" because of all of the earthquakes. It seems that a risk of a tunnel collapse would be worse than the risk of a landslide in terms of the impact on the water flow. I hope they don't spend $84m in vain.
