    You can't. It's a Source limitation (yay for old engine). Only one level of water is allowed that can be seen at any given time. If you have multiple levels of water that can be seen and are rendered at the same time that both have reflections (real-time or cubemapped) and refractions they instantly break each other.

    I think lunarpumpkin is saying that he has a water brush above another water brush like the left-image shown below, and that when he swims from the lower brush into the above-one he sees the top of the water of the lower brush in the wrong spot:

    Compared to the image on the right which is how he could want to make the water brushes instead?

    The only way I've been able to do this is to make an invisible water texture, and have an animated water overlay above that(a refract texture). Basically, take your water, and put $alpha 0 in it. It works best on those old DX7 water textures without any refraction.

    Sadly, as a result, you won't have any above water fog.

    Yea, you can't have water on two separate levels in the same area(or at any angle besides it being a top face). You'll have to find a way to separate them with an area portal, or do what I said in my post above.

    The water setup shown in Egan's right image is how many underwater routes are created in official maps, so that's not the problem. However I can't really help considering two out of three images make no sense to me. I mean, what am I looking at?

    The exact rule is that you can not have expensive water at two different heights in the same PVS. So either break PVS or substitute cheap water.
