Block 8 is used for water that is actively spreading and creating more water blocks, such as the advancing edge of water that has just been poured down a hill.
Block 9 is used for water blocks that are not actively spreading (and thus not creating new water blocks). So a waterfall that is flowing, but not creating any new water blocks, will be made entirely out of block 9.
Flowing: Whether or not the water is "flowing" (i.e. it has a moving texture, and a current that can push pickups) is unrelated to the block ID. Both block 8 and block 9 can be static (like a source block) or flowing (like a water fall). For both blocks (ID 8 and ID 9) a data value of "0" will make them static water, while data values of "1" through "7" will make them various depths of flowing water, and finally a data value of "10" will make both blocks falling water.
My test (from post #10):
Okay, I just tested it out, and yes, block 8 is used to track the actively spreading tips of water, after it was just poured, or otherwise prompted to spread in some fashion.
That is, block 8 is used whenever water is spreading or pouring in a way that creates new water blocks.
For example pouring water down a hill creates a growing snake of new water blocks. The advancing head of the snake is an "ID 8" block, while the body is all "ID 9" blocks. This is because the "ID 9" blocks are now stable, and don't have the opportunity to spread any farther. Once the head of the snake ("ID 8" block) reaches the bottom of the hill, and can no longer spread any farther, it too becomes an "ID 9" block, because it is now stable. So, when the entire waterfall is done spreading out, and is just sitting there on the side of the hill, all of it will be made of stable "ID 9" blocks.
I think the confusion came from the block names shown on the wiki. I was incorrectly thinking that "Stationary water" meant a water block with no water current, (the kind of water current that pushes pickups). However, "Stationary water" in this case doesn't mean that water current within the block is stationary, it means that the actual block of water is stable, and not attempting to spread out by creating new water blocks.
So, the reason I couldn't find any examples of block 8 in use was because unless you just poured out a bucket, most of the water blocks you encounter will have already settled into their stable state, transforming them into "ID 9" blocks.

It looks to me like water block 8 is never used, while water block 9 is used for all forms of water within Minecraft.
Can anyone else confirm this? Or am I maybe missing something?
I created a few maps, and inspected the blocks that make up water, lakes and waterfalls, and they are all block 9. (To inspect block properties, you can open a world in MCEdit, and mouse-over any type of water block while holding Alt.)
The only difference between source blocks in lakes and falling or flowing water is the data value.
A water source block is 9:0 (i.e. Block ID "9", and Data Value "0").
Flowing water blocks are 9:1 to 9:7, for the 7 levels of flowing water height, 7 being the shallowest.
Vertically falling water blocks are 9:10.
Strangely, on the Minecraft wiki, block 8 is titled "Water", and block 9 is titled "Stationary water", even though block 9 seems to be used for all types of water. http://www.minecraft...88175#Block_IDs
So, is the water block with the Block ID "8" just not used any more?
[edit] Here are some screenshots from MCEdit showing water block 9 being used for a range of water types:
Static Water Source Block - 9:0:
Static Water Source Block - 9:0: (A block at the bottom of a lake.)
Flowing water - 9:7: (Note that MCEdit renders all types of water as cubes.)
Block 08 is "flowing water" - this is what is placed by a water bucket. It updates immediately when it is placed. Block 09 is "stationary water" - it does not flow when placed (/give username 09 and then placing it will place the water source only). However, if you place a block next to the stationary water block, or update that block in any other way, the water will start to flow.
This goes for lava too: Block 10 is flowing lava and Block 11 is stationary lava.

What you described is what I initially thought, until I actually began inspecting Minecraft world data by hand.
What I'm trying to say in my first post, is that it looks like block 8 is never used to represent water at all.
Everywhere I found water of any kind, static, flowing, falling, or placed from a bucket, the block ID is always "9". Block "8" never seems to be used anywhere.
I'm aware that block 8 is titled "Water", and block 9 is titled "Stationary water", in the Minecraft wiki, which I linked to in my first post. That was actually the reason I found this so strange. The names, don't seem to accurately describe how the blocks are actually used. Maybe they did in an earlier version of Minecraft, or maybe I'm doing something wrong.
If you want to see what I'm talking about for yourself, open any modern Minecraft world in MCEdit, and mouse over a water block while holding Alt. An information popup should appear near your mouse pointer showing the properties of the current block. All water blocks are shown to have the ID "9". Only their data value changes depending on what the water is doing. Static water gets data value "0", flowing is "1" to "7", falling is "10".
Here are some screenshots from MCEdit showing water block 9 being used for a range of water types:
Static Water Source Block - 9:0:
Static Water Source Block - 9:0: (A block at the bottom of a lake.)

Falling water - 9:10:
I've also seen the same total absence of water block 8, using other world inspectors, so I don't think it's just some bug in MCEdit.
Again, I might be overlooking something, but I've tried several ways to find any examples of water block 8 being used in Minecraft, and I haven't seen any. Everything is block 9 from what I'm seeing.
That's pretty interesting, I guess I didn't carefully read your original post (sorry 'bout that). What I said was pretty much copied directly from the wiki, and although I'm sure the wiki data is consistent with the game code, I don't see how it can be consistent with the actual results. I'll do some tests with blocks 8 and 9 when I get home from school tomorrow and I'll let you know what I find.

No problem Shadowx4ffc.
Thanks in advance for checking it out on your end.
Maybe it's there just in case someone wants to use stationary water?
Non-enclosed air domes on the bottom of oceans would be cool for an Atlantis style adventure map.
A suspended underwater air environment is an interesting idea.
Though, that's what's so weird about the block titles. Block "9", the block used for all water, is the "Stationary water" block. It's the seemingly unused block "8" that's just named "Water".
I'm not sure I quite understand. Do you mean that an actively spreading waterfront is made of "ID 8" blocks, and that this spreading will leave behind a trail of "ID 9" blocks.
That is to say, "ID 9" blocks can make up waterfalls, but they are "stationary" in the sense that they are stable in their current position, and are not actively spreading out, as if just poured from a bucket?
This is the only other thing I could think of that "ID 8" blocks might represent. This could make sense from the perspective of programming water. This way, only the actively spreading tip blocks of water need to be handled by the game engine.
I think that makes sense, at least. I'll test it out soon.

If Block 8 refers to water that does not flow when placed, than I would say...
Melted ice. Ice blocks that melt turn into a single isolated block of water when placed next to a non-sunlight light source, so I'll go ahead and test this really quick.
