    Do not add sand to clay!For 1 thing it will wash out of the bank and for two clay + sand = cement!Broadcast compost.
    This will make my 2000th post pat me on the back

    I agree with sheshovel (pat pat pat) organic material is what you need to build in the profile, topdressed after aeration for many moons to come. watch your water and depth of topdressing to make sure that you don't create host for more fungal probs, but otherwise, load up a fine screened compost and have at it!

    If you aerate the area well, IMHO there is absolutely nothing wrong with topdressing with a 50/50 mixture of organic material and sand.

    The sand would actually help improve the drainage of the clay.

    I was always given this mental picture to think about: Think about putting some marbles in a jar full of flour. The sand represents the marbles, the four represents the clay. As you can "see" the sand is going to no nothing at all to improve the aeration of the soil, nor is it going to help it hold or shed water better. You would need a to be able to amend the soil till there was a much higher ratio of sand to clay to achieve any benefits.

    Golf courses and athletic fields use sand to top-dress only because greens and athletic fields are built on a sand (or at least a 75%) sand base.

    The only way to ammend soils that are primarily loam and clay is to use organic material and aeration.
