I wouldn worry too much, but there is always that one exception. How close to the drainage ditch is the house?
Most of the time when a dam fails, it's because of erosion and water running over it. This creates a trench that gets deeper and deeper as the water cuts through the dam. The water is rushing out, but just at that one location.
The odds of the entire dam failing at once and all the water coming out are very, very slim.
What I want to know is why would you want to live below the dam and have that for your view? Is the house already built? Whatever it costs, it's worth it to have the view of the water instead of the dam.
