Hello
My name's Tai . I want to calculate volume of water and depth of a lake. But i dont know method to do it. Would you mind teaching me method to do it in acrviewGis and Envi software, please ?
Thank you very much !

What kind of lake data do you have? Contours?
Have a look at this: http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?id=1226&pid=1221&topicname=Surface_Volume_(3D_Analyst)
and this: http://webhelp.esri.com/arcgisdesktop/9.3/index.cfm?id=1283&pid=1277&topicname=Cut/Fill_(3D_Analyst)

Those links give me a "Sorry, that topic cannot be found" error.

Hmmm, me too.
But if you click on the highlighted topic on the left, it reloads properly.

Didn't think of clicking that! Works for me now.

Hi ! Lady_Jane
Thank you very much for your help !. I only have a DEM of lake watershed, high points of land in lake watershed. I don't have any points in bottom of lake. If I want to do it with arcview 3.3 , can I finish it ?

You need bathymetry data for accurate calculation. Model the lake bottom to create a TIN surface then use the 3D Analyst to calculate the volume bellow surface. You can also do this with Spatial Analyst using raster data and the Cut and Fill tools. You could also assign an approximate depth to get a very rough volume estimate. To calculate volume this way you can extrude the lake polygon to the approximate depth then convert to multipatch feature. Once you have a closed multipatch feature, use the Add Z Information tool to calculate volume.
Not sure about ArcView 3.3. You will probably also need the legacy 3D Analyst extension to complete the volume calculations.

Well, I think this is little bit difficult to say exactly but I can say something about it. The amount of water required to cover of an area of one acre to the depth of one foot. One acre-foot of water is similar to almost 326,000 gallons.
