Pond Boss Forums POND CONSTRUCTION Soil questions How to get grass established on clay?

I've had a soil test done. Tilled in the fertilizer per A&M instructions. I even tried putting out some sod this year. The Bermuda sod took in a few places but not much. I don't want to be discouraging but I have had absolutely no luck. I even built a pvc sprinkler system to water on the weekends. I wanted the grass for aesthetics but mainly to try to help clean up the muddy water. I can't leave anything undone so I'll just keep plugging away. I do think a compost mixture or topsoil with something on top to keep it moist as the others here suggested is the way to go. I'll have to try that in the spring I guess. Definitely start with a soil test.
