I have 2 naturally running springs in different locations on my property that I am thinking either both combined or one of them would put out enough water to build a small pond. I am talking about a very small pond (somewhere around 10' x 16' or so and somewhere around 4-6 ft deep). I want to have some nice landscaping around it, but nothing fancy because it will be in a natural area which stays fairly shady because of the trees around it. I am willing to lose maybe 3-4 small trees but nothing larger for privacy reasons. I want it to stay fairly clean as well. I was thinking of lining the bottom w/ some sort of large rock for looks. Has anyone done anything smaller like this that was more of a clean garden pond using a natural spring. I don't want a lake or muddy pond. I would probably try to use a small bit of algacide occasionally, but it would be a small enough amount to not harm a few fish in there to help clean it up (I have seen this done before). What do I need to find out about the soil? What type of rock? What are some easy ways to lay out the boundaries and figure out where the edges would be w/ a dam? Any tips on building a dam? Thanks.
