Fluid has odd shape

I can’t figure out how to get the fluid shape to look more like fluid/water.
I realized I wasn’t descriptive enough to say what part is odd. Where the water contacts the floor/ground, it has and edge above the floor/ground - that to me seems odd.

I’ve changed the settings in various ways and can’t get it any better than this.

Any ideas?
