Looking for some good internet sources for maps of China with a fair bit of detail.
Any suggestions?

If you go to Google, and put in 'china map', you will get a plethora of sites.

But my choice would be <b>http://encarta.msn.com/encnet/features/mapcenter/map.aspx</b> for all the info you could want.

Thanks for pointing me in the right direction Jed. I have in fact found out that multmap.com gives slightly better results, although I'm still having difficulty find some places, possibly due to dubious spelling.
Can anybody locate Lijia as in Lijia Gorge Hydropower Station in Qinghai province?

Lijia is a small town on the Yellow River. Looking at my atlas, it's about 300km SSW of Xining, on a secondary road that goes all the way down to Sichuan.

The Yellow River flows Southeast to Northwest over there.

The closest bigger city is called Maxin (or something like that).

Great stuff rkkwan!
I've now got the general area but still can't quite pinpoint it yet. If you've got nothing better to do ;-) would you try and give me the approx longitude and latitude on your atlas?
Much appreciated, Mark.

Smalley - The previous information I gave you was not right. I was looking at the wrong place.

Now, the actual real stuff. The name of the dam is Lijiaxia. Xia means gorge, and there isn't a town just called Lijia near it.

It is about 55km due south from Xining, and the elevation of the river there is about 7,200ft.

Firing up my Google Earth program, the best coordinates I can give you is this:

36 07 05N
101 48 31E

The dam is visible on Google Earth.

I'm glad you use Google Earth rkkwan, because I was looking with it also. I'm still a bit confused though, because your coordinates refer to another dam to the west of the one due south of Xining. Here's a link to the screenshot I saved to illustrate: http://www.flickr.com/photos/marksmalley/tags/china/, but I assume you mean the easten one.
The reason for all this interest in such an unknown place is that it's on an itinerary that someone has suggested to us, with a boat trip across the lake to a nunnery and a temple.

Smalley - I copied the coordinates directly from the Google Earth, but rounded to the closest &quot;second&quot;. I will double check.

But anyways, from your screenshot, there are two dams. The one on the west which created a huge reservoir is Longmenxia. Lijiaxia is the one that's directly south of Xining, creating a much smaller lake. The height of the dams are similar, I believe.

If you pan to the east, there's another large dam close to Lanzhou in Gansu. That's Liujiaxia.

Sorry, the large one to the west is Longyangxia. Got the name trasnlation mixed up again.

Thanks again rkkwan.

I just got home and checked Google Earth. The dam for Longyangxia, which formed that very large lake is at:

36 07 21N
100 55 10E

The previous coordinates are correct.
