I DON'T KNOW but the dredge that was ancord in Stockton was probably either the Sacramento or the liberty, they were all steelconstruction and were owned by Dutra. A better description of the tecniqe of swining and controling the long boom dredge in on p.s 94 & 95 of T Thompson and Dutra's Tule Breakers book.The dredge Francis is located in McArthur.

Thank you all for sharing these early facts. I lived in the south bay area for 13 years, fished all around where tthe Mallare II worked. Lived there in the 60's-70's and spent many an hour fishing the South Bay! I have also seen one in West Sacramento, not far from where the hwy 80 and 50 split, it was on the south side of the freway, you could see the boom for miles. I have to get a copy of that book to read, again thanks for sharing.

I have often seen Dutra barges filled with rip rap/huge rock up and down the Sacramento river along Walnut Grove to Freeport. Interesting services they provide. JM

Found them, There are 2 steel clam barges, one crane barge probably with the 88B on board and several rock barges in the Rio Vista Dutra yard
