When you get the top off, can you take a picture of the dams in place and post it here?
You need to upload the picture to PhotoBucket(free registration) then copy the URL link to the picture, then make two of the following in the in this message box; [img], then copy the link in between the two of them.

After you sign up in Photobucket and before you 'upload' the picture from your harddrive, be sure to select 640x480 in the 'reduce to' box at the bottom of the 'upload' box. Otherwise the picture will be too big for the computer screen and cause one to have to scroll up and across to see the whole picture.
