Thank you all. Funny enough, I got grass to grow on the dam fairly well. All I did was take a stone rake to it to loosen the clay, threw down seed, and it took off. The trouble is my backyard. The contractor that dug the pond cleared the entire field (roughly 9000 sq ft), and it all washes into the pond every time it rains. I feel like it's going to take some serious work (and money) to fix everything.
I also don't feel like it's holding water very well, either, but that's a topic for another day.
