Pond Boss Forums POND CONSTRUCTION Selecting a site Examine my land please :)

I can only relate this observation.

I have sandy soil, with some clay mixed in that was dug out of the pond. Not enough clay to hold water, not even enough to make it "sticky" when wet. But, once the ground is soaked, I have surface runoff into my pond. The ground drops about 45 centimeters from the road to my pond, and that horizontal distance is about 140 meters. The water will run from up near the road all the way to the pond thru the grass.

Once it gets close to the pond, the drop increases slightly, and if there isn't any plants to hold the soil together, the water will cut a 30 centimeter deep channel in the ground. It doesn't take much of a slope to get the water to run in any one direction.
