There is also the Consumnes River which crosses I-5 north of Stockton. It's the last uncontrolled river in the state. Depending on how much WW you want to deal with paddling a good chunk of that then into the delta and eventually the bay would be a nice trip.
FWIW, the Sac runs high enough for human powered craft year round.
