I purchased 30 acres of land with a tank this year. The land is mostly sandy soil with some 50 foot elevation change from one end to the other. The previous owner added a berm to a natural slope to create a tank but it does not hold water.

I'm looking for advice on how to best make the tank hold water. I'd also like to make it larger. I'd like to do the job property even if that means I need to save money to have help from someone with the proper equipment. I'm just not very experienced with this and could use some help.

This is the tank last March. I've not owned the land long but this is about as high as I've seen it.


This is the tank yesterday. I don't know how much water is left in the bottom but it is only about 2-3'. It was full as in the previous picture three months ago.


The bottom looks to be the same sandy soil that is all over the property. There are some areas where the bottom appears to be a large sheet of rock.
