I use a mesh onion bag filled with rocks that I get at the launch site. Tied off with some good 1/4 in. limp nylon rope with the "top" crimped so if you really had to pull hard the rope would slip off - leaving the mesh bag with rocks on the bottom. Then go to shore and do up another bag of rocks. Usually travel with two extra bags (we eat a lot of onions). Cheaper than an anchor or dumbells at Walmart - and on a lake it works just fine. On a river with some quick water - just use heavier rocks.
