Conditions look good this week, with relatively low flows and low tide during the day. SumCo spent the morning pulling back rubble left from demolition of the center spillway, and is now back at work continuing the demolition of the south spillway. This section of the dam is much more massive than the last; its demolition should take the better part of the week--if we don't get any rain and flows stay low. Following the demolition, SumCo will remove all concrete rubble from the river, filling steel containers to be hauled out by crane. Here's what it looks like now. The orange turbidity curtain is in place to prevent concrete dust from the demolition from moving downstream with the current.
