Water

Here in Phoenix at the local parks (and some people do it at their houses), they water by a technique called flood irrigation.   Basically, they flood the area they want watered. 

This is how it looks at the park where those Easter eggs were chalked on the sidewalk in my Neighborhood post about 10 days ago.  

The ducks (and Canadian geese) like it when it is flooded.  You might be able to see a duck in the middle of this picture.

It looks like a lake in the middle of a park.  But it is just temporary.  

This is about a week later.  You can see the water in some placed has receded.

But not in all of the areas yet.  Usually takes about 2 weeks for it all to recede.

This one was taken Saturday April 23rd.  I kind of like the sky effect in this one.

And these last two from yesterday, April 26th.  Water all dried up.  

First time I saw the park covered with water (they do sections at a time), I thought a water pipe had broken.  It took me awhile to learn about flood irrigation.  A lot of new people to the area also are shocked when they first see it until they too learn about it.  From what I read, it is more effective for watering with less evaporation because of the heat we have here.  

They have been doing it for years so I guess it works.

I just found it odd when I first saw it.
