Teachers! This is an opportunity for you to use Google Earth 3d to your advantage in the classroom. The basics of canal design can be demonstrated by looking at these satellite views of Lock 19 and its vicinity.
In the view above, the camera is looking west. Water flow is from right to left and from the top to bottom. How do you know that? (Your students may ask.) Look for the white of water flowing through the lock gates near the center of the picture and the white water flowing over the flood control dam where Sterling Creek joins the canal.
