Sitting behind the Westside Recreation Center/Galatzen Park, on Wallenberg drive, is a large drainage basin formed by the earthen dam between Sunland Park Mall and I-10:

I went back to walk around the wash basin and kill some time at lunch. The area is quite green despite the lack of rainfall.
Parallel to a walking path that rings the area is an arroyo fed by the termination of a large drainage ditch that snakes through the westside. Its all downhill and by the time water reaches this area it can very forceful as evidenced in the great flood of 06, washing out part of Mesa Hills.
I didn’t notice it before but there is a mini canyon in the arroyo that looks like it holds water year round:
I saw quite a few birds around as well as a fox, who darted into his den on the side wall of the canyon. It might be a good area to do some bird or animal watching if you had the time.
The walls are very steep with lots of loose rocks so you have to be careful if you approach it from the side. The pond can be reached by walking down the rocky arroyo from one end or by walking down to the wash basin.
The shopping cart helps give you a sense of the scale. The pond had lots of tadpoles in it so the foxes may be here to feed on frogs or birds. Its an interesting, self contained ecosystem carved by what little rain we get throughout the year. A few more pics can be found below:
