Jon boat anchor

[Brian4618]

I have a 10lb mushroom anchor that I use in lakes and ponds, but im gonna be going to a small river soon where there is more current and im not sure how well the anchor I have will hold up. What is a good anchor to keep me from floating down the river? Ill be in a 14' jon, Thanks.
