Knots for paddlers:

There are four knots leaders should know: the bowline (loop knot), the figure-8 (loop and stopper), the truckers' hitch (ties boats to cars) and the constrictor knot (no-slip knot ties to water bottles and other gear).

Advanced: Knots needed for swiftwater rescue include the water knot (joins ends of flat webbing), the double or triple fishermans knot (used to make Prusik loops), and the Prusik knot and the girth hitch (used to make adjustiable haul lines).

All of these and many more are fully shown at the excellent website animatedknots.com.
