About a mile to the NW of Eisenhower Lock lays a small chain of islands connected by road causeways and collectively they form an extensive wooded camping area.
It is possible to anchor in just about any of the southern coves between the islands but the cove on the south eastern side of Hoople Island appears to be the best option. Anchor in about 7-8m of water with good holding in mud. This is a very peaceful area, well out of the main stream of the St Lawrence and the campsite is large and dispersed enough that you will probably not even see the tents from the anchorage.
