Why does Google Maps API show more detail than

I went to fish lake today, found the lake info on this URL, it uses google maps API.

I went to, and it doesnt have the lake, the road is a little different, and the Topo info isnt the same zoom level.,+-121%C2%B0+3%27+54.00%22

Any ideas why they are different? I noticed yahoo and microsoft are also missing updated info on lakes in the areas.

Google Maps uses data from NAVTEQ, while the API serves up data provided by TeleAtlas, presumably because of licensing issues. Nathan Torkington has a post on O’Reilly Radar entitled "Google Maps and Their Data Providers" discussing exactly this issue. In fact, the TeleAtlas FAQ specifically mentions the Google API functionality.

Note that the API isn't always more detailed; in tracing the route of the Boston Marathon last year, I noticed that there were areas where had more detail, and other areas where the API provided the best detail. It's a bit insane, actually; there are clearly reasons for the need for two map data providers, but it's a need Google should work to eliminate.

Anecdotally, in every instance I've ever come across where they differ, it's always been showing more accurate information than the API version.
