Not sure about any dredging but a few years ago we took a great trip to Petaluma. We left Rio Vista and went towards San Francisco, hung a right by the Mothball Fleet and went north up the Petaluma River. Great cruise up the Petaluma River, called the bridge tender at the D Street bridge and ended up in the Petaluma turning basin. Spent the night in the basin, visited many of the American Grafitti movie sites and walked around Petaluma....great little town...lots of history. A wonderful cruise...watch the tides
