If you look at Kakariko Village in
TP you will notice there are a couple areas of water, one of them is being fed by a waterfall from a misterious water source...
if you look at this map of kakariko village you will see what i'm talking about
Now look at a picture that shows where the land is higher (sorta like a topographical map)
The King Zora Grave Site is fed by waterfall, so where does this water come from? lets say there is a small fresh water spring here--
ok, so we figured out where the water comes from, now look what happens if you create a larger water soure --it over flows, creating a river

^^now if you look at the higher levels of land you will see the water has to follow the path to hyrule field, and into zoras river like i showed in the picture
now if you have a larger water source, theres a possibility it may find another path downhill. lets say the large water source finds a path to Kakariko Gorge then it would look like this
now if you block off the northern part of Kakariko from the southern part like this, and increase the flow/amount of water..
it would (possibly) cause the village to flood creating a lake/pond like this
So, is it just me, or does this look (slightly) like Zoras Domain/river from
OoT?
It would make sence if it was zoras domain, because King Zora is buried there, it has a passage to lake hylia, and it is a "Sacred place" for the zoras..
so if this is Zoras Domain, what happend? well obviously the fresh water spring that provided all the water shrank causing the river to dry up, and forcing the zoras to migrate somewhere else.
--also i would like to make a note that i made all of these pics in about 5 minutes, so if they're crappy, i'm sorry--
