I love it when it rains.  Actually, most desert-dwellers welcome the rain.  Believe it or not…the rain is a welcome change to bright, sunny days.

The park near my home is starting to fill up with water – this is supposed to happen.  Two previous storms this week have started the process, but we are expecting a very large storm to hit today which could bring 3 – 4 inches more (which is a lot for us).

I notice the park filling up when I took my children to school this morning, so I ran back home and got my camera and returned to take pictures.

Look around an urban desert landscape and you are likely to find examples of the above, which is known as a detention basin or dry pond.  The purpose is to hold large amounts of water from rainfall and keep it from flooding the streets.  

During the summer months, we often receive periodic torrential rains over a short period of time.  These dry ponds rapidly fill with water, which helps to prevent flooded streets.  The water in the pond is then slowly released via a small outflow opening.  Water usually stands in these basins for 24 – 48 after rainfall ends.

Most parks in our area are dual purpose; they serve as a park, but also as a detention basin.  The edges are raised up, forming a bowl shape, which allows them to hold water.

I snapped this photo this morning of a group of Mallard ducks taking advantage of our now wet ‘dry pond’.

Do you want to know what my favorite part is about the rain?
