"Am I seeing wet spots on the shot-create vertical wall at the end of the broken spillway?"
The wet spots are from the drilling activity. There are multiple drill locations that had spill coming over the concrete lip and down the face of the shotcrete. Indicators are there have been at least seven drillings in an "array" pattern.
The water in middle section of the spillway is the same type: water running off of the surface of the lip of the spillway and onto the face of the shotcrete. They may have drilled at that location too, but the zoom does not show any residual indicator (other than an orange safety cone).
"That wall is not going to hold up if they did not put in proper drainage."
White PVC type drain pipe was emplaced into the backside rock before the shotcrete was applied. The drain pipe has been cut flush since then and is less visible unless you have a good resolution pic to zoom with (even then the flush cut ends are pixellated). The pic in the FRpost below shows four of these pipes protruding under the scaffolding. This is before they were cut flush to the shotcrete surface. (zoom indicates near six total pipes installed).

Regarding the "bids" and awarding. Post summary information indicate that the award went to the lowest bid cost of $776,055.00.
Close in view of emplaced drain pipe in shotcrete repair (end of damaged main spillway)
Here's the drain pipe that was emplaced in the bedrock prior to coating a layer of shotcrete. The last photo referenced (posts 2,432 & 2,433) was at an angle where the drain pipe appeared to be truncated to the wall surface. This new shot proves the pipe has not been cut flush.
note to the curious: This piping is to allow any water- that may penetrate from within the bedrock - to drain beyond the shotcrete repair/re-inforcement. While the spillway is in operation, the water could develop a "pressurized" force via the water pushing against the shotcrete inner wall and risk compromising the shotcrete repair.
