Starting in August 2019...

After seeing the kids at Vesper break their backs shoveling out a couple cubic feet of silt...Anyone ever use one of these?

The real dredging might experience a bit of a delay... barges wedged under the Chestnut St bridge.
The Schuylkill crested 2.5 ft over flood stage combined with a high tide early this AM wreaked havoc.

the miles of pipe seem to be a bit worse for wear too (especially below the falls)

This is a question for other Philly people, does anybody have any confidence at all in the contractors they got to do the dredging? They've been there for two months and it looks like they've achieved nothing. Dredging boathouse row was supposed to be done by September, that seemed unlikely even before their barge broke loose and the pipes went over the falls--seems impossible now. Is there a chance these guys will spend a bunch of money, achieve nothing, give up, and leave us with no dredging and a lot less money?

After watching the Cooper, which was ostensibly an easier job & the timeline and cost overruns they had, i was expecting worse with the Schuylkill.

Atlantic Subsea seems competent, http://www.atlanticsubsea.com/

But i think the scale of the project as well as the location/access leads to both different size companies & different types of equipment being used.
Whats going on now looks just like the maintenance dredging that the USACE does on the channel of the lower Schuylkill (downstream of the Fairmount Dam) but this is like a fresh dig rather than maintenance, so there are debris issues (and pandemic and now hurricanes)





For comparison - the USACE fact sheet on the Schuylkill dredging project (60,000 cubic yards) vs the Delaware shipping channel dredge (20 million cubic yards)

To the point of how much silt is stuck down there...
Recently the city christened a new "park" which exists where boats used to moor.
