The material in my dam doesn't seem fit for grass of any kind. The cored up clay holds a little growth, but with more and more rainfall, I end up with fingernail sized rock, embedded in clay. The erosion isn't very bad, and there are no leaks, I'm finally 6' away from reaching my spillway. My germination and watering is left up to Mother Nature, hopefully the sooner or later something will take. Without watering, it's seems futile.
