For those that don't know power-pole makes an anchoring system for shallow water. They are mainly used by bass guys and saltwater flats guys but some might have an interest up here. They make a few different models that can anchor in as deep as 10 fow and also make a kayak version as well.
More details on their website.

If anyone has interest in purchasing a power pole system let me know because I just won a $250 USD gift card in a fishing tournament and will be looking to sell it for a good deal.
