We had a question today about anchoring in the Delta: Is one Danforth anchor enough?
The simplified answer is probably not.
On Stink Eye, we have two Danforths, a lightweight 'lunch hook' or racing anchor, and another heavier Danforth. We also have an extra long line for tying off to a tree. Currents can be strong and will switch around in the middle of the night, so one anchor is not usually enough unless you are in a big anchorage with plenty of room to swing (rare in the Delta). For a really good night's sleep, a three-point tie-off is the most secure (hence, two anchors plus a bowline to a tree).
The bottom will be soft mud, or mud with grassy weeds. The weeds can sometimes give a 'false set'. Jonathan says, "Back down hard to make it bite," and "Bigger is better."
Here is a good primer on anchoring:
