Create some walls

In this example, I made this little rectangular pool, but you can also use differently shaped structures.

Fill in your water

Draw a brush that is going to be your water volume and texture it with common/nodraw

[It has now been recommended that nodraw solid be used instead of nodraw as sometimes the water fails to function. - Fidcal]

Create the entity

In DarkRadiant: Select your brush, RMB -> Create Entity -> func_liquid

In the Entity Inspector you can see that the classname is now func_liquid, and the name func_liquid_1 (or a higher number if there are also other water sources present) It should also have a blue outline in the orthographic view (The XZ Front in this case)

Texture the surface

Select the face that is going to be the surface (Ctrl - Shift - LMB) and texture it with a nice water texture, for example Water_source/water_clear.

Do not assign the water texture to the whole brush, or you will see this: (You can also get rid of that z-fighting by dragging the brush into the wall so that it insersects with it.)

Test your water

And there it is!
