I have an existing 5500 gal pond that we put in 2 years ago. Of course I have the fever and now want to add a smaller pond with a connected stream. My question is what is the necessary slope of the land to support this idea. My property has a gentle slope to it with the large pond about half way down the property. I was hoping to have a smaller pond at the top with a stream connecting to the larger pond. I was hoping to have the water drop into the larger pond however depending on how deep the stream needs to be there may not be enough slope. How do you calculate something like that and is there anything you can do if the slope is not great enough? Thanks
